◆ OrthancPluginIncomingCStoreInstanceFilter

typedef int32_t(* OrthancPluginIncomingCStoreInstanceFilter) (uint16_t *dimseStatus, const OrthancPluginDicomInstance *instance)

Signature of a callback function that is triggered whenever Orthanc receives a new DICOM instance using DICOM C-STORE, and that answers whether this DICOM instance should be accepted or discarded by Orthanc. If the instance is discarded, the callback can specify the DIMSE error code answered by the Orthanc C-STORE SCP.

Note that the metadata information is not available (i.e. GetInstanceMetadata() should not be used on "instance").

Warning: Your callback function will be called synchronously with the core of Orthanc. This implies that deadlocks might emerge if you call other core primitives of Orthanc in your callback (such deadlocks are particularly visible in the presence of other plugins or Lua scripts). It is thus strongly advised to avoid any call to the REST API of Orthanc in the callback. If you have to call other primitives of Orthanc, you should make these calls in a separate thread, passing the pending events to be processed through a message queue.

Parameters

dimseStatus	If the DICOM instance is discarded, DIMSE status to be sent by the C-STORE SCP of Orthanc
instance	The received DICOM instance.

Returns: 0 to discard the instance, 1 to store the instance, -1 if error.

◆ OrthancPluginIncomingDicomInstanceFilter

typedef int32_t(* OrthancPluginIncomingDicomInstanceFilter) (const OrthancPluginDicomInstance *instance)

Signature of a callback function that is triggered whenever Orthanc receives a new DICOM instance (e.g. through REST API or DICOM protocol), and that answers whether this DICOM instance should be accepted or discarded by Orthanc.

Note that the metadata information is not available (i.e. GetInstanceMetadata() should not be used on "instance").

Warning: Your callback function will be called synchronously with the core of Orthanc. This implies that deadlocks might emerge if you call other core primitives of Orthanc in your callback (such deadlocks are particularly visible in the presence of other plugins or Lua scripts). It is thus strongly advised to avoid any call to the REST API of Orthanc in the callback. If you have to call other primitives of Orthanc, you should make these calls in a separate thread, passing the pending events to be processed through a message queue.

Parameters

instance The received DICOM instance.

Returns: 0 to discard the instance, 1 to store the instance, -1 if error.

◆ OrthancPluginIncomingHttpRequestFilter

typedef int32_t(* OrthancPluginIncomingHttpRequestFilter) (OrthancPluginHttpMethod method, const char *uri, const char *ip, uint32_t headersCount, const char *const *headersKeys, const char *const *headersValues)

Signature of a callback function that is triggered whenever Orthanc receives an HTTP/REST request, and that answers whether this request should be allowed. If the callback returns "0" ("false"), the server answers with HTTP status code 403 (Forbidden).

Pay attention to the fact that this function may be invoked concurrently by different threads of the Web server of Orthanc. You must implement proper locking if applicable.

Parameters

method	The HTTP method used by the request.
uri	The URI of interest.
ip	The IP address of the HTTP client.
headersCount	The number of HTTP headers.
headersKeys	The keys of the HTTP headers (always converted to low-case).
headersValues	The values of the HTTP headers.

Returns: 0 if forbidden access, 1 if allowed access, -1 if error.

Deprecated:: Please instead use OrthancPluginIncomingHttpRequestFilter2()

◆ OrthancPluginIncomingHttpRequestFilter2

typedef int32_t(* OrthancPluginIncomingHttpRequestFilter2) (OrthancPluginHttpMethod method, const char *uri, const char *ip, uint32_t headersCount, const char *const *headersKeys, const char *const *headersValues, uint32_t getArgumentsCount, const char *const *getArgumentsKeys, const char *const *getArgumentsValues)

Signature of a callback function that is triggered whenever Orthanc receives an HTTP/REST request, and that answers whether this request should be allowed. If the callback returns "0" ("false"), the server answers with HTTP status code 403 (Forbidden).

Pay attention to the fact that this function may be invoked concurrently by different threads of the Web server of Orthanc. You must implement proper locking if applicable.

Parameters

method	The HTTP method used by the request.
uri	The URI of interest.
ip	The IP address of the HTTP client.
headersCount	The number of HTTP headers.
headersKeys	The keys of the HTTP headers (always converted to low-case).
headersValues	The values of the HTTP headers.
getArgumentsCount	The number of GET arguments (only for the GET HTTP method).
getArgumentsKeys	The keys of the GET arguments (only for the GET HTTP method).
getArgumentsValues	The values of the GET arguments (only for the GET HTTP method).

Returns: 0 if forbidden access, 1 if allowed access, -1 if error.

◆ OrthancPluginJobsUnserializer

typedef OrthancPluginJob*(* OrthancPluginJobsUnserializer) (const char *jobType, const char *serialized)

Signature of a callback function that unserializes a job that was saved in the Orthanc database.

Parameters

jobType	The type of the job, as provided to OrthancPluginCreateJob().
serialized	The serialization of the job, as provided by OrthancPluginJobGetSerialized.

Returns: The unserialized job (as created by OrthancPluginCreateJob()), or NULL if this unserializer cannot handle this job type.

See also: OrthancPluginRegisterJobsUnserializer()

◆ OrthancPluginReceivedInstanceCallback

typedef OrthancPluginReceivedInstanceAction(* OrthancPluginReceivedInstanceCallback) (OrthancPluginMemoryBuffer64 *modifiedDicomBuffer, const void *receivedDicomBuffer, uint64_t receivedDicomBufferSize, OrthancPluginInstanceOrigin origin)

Signature of a callback function that is triggered whenever Orthanc receives a new DICOM instance (through DICOM protocol or REST API), and that specifies an action to be applied to this newly received instance. The instance can be kept as it is, can be modified by the plugin, or can be discarded.

This callback is invoked immediately after reception, i.e. before transcoding and before filtering (cf. OrthancPluginRegisterIncomingDicomInstanceFilter()).

Warning: Your callback function will be called synchronously with the core of Orthanc. This implies that deadlocks might emerge if you call other core primitives of Orthanc in your callback (such deadlocks are particularly visible in the presence of other plugins or Lua scripts). It is thus strongly advised to avoid any call to the REST API of Orthanc in the callback. If you have to call other primitives of Orthanc, you should make these calls in a separate thread, passing the pending events to be processed through a message queue.

Parameters

modifiedDicomBuffer	A buffer containing the modified DICOM (output). This buffer must be allocated using OrthancPluginCreateMemoryBuffer64() and will be freed by the Orthanc core.
receivedDicomBuffer	A buffer containing the received DICOM (input).
receivedDicomBufferSize	The size of the received DICOM (input).
origin	The origin of the DICOM instance (input).

Returns: OrthancPluginReceivedInstanceAction_KeepAsIs to accept the instance as is,
OrthancPluginReceivedInstanceAction_Modify to store the modified DICOM contained in modifiedDicomBuffer,
OrthancPluginReceivedInstanceAction_Discard to tell Orthanc to discard the instance.

◆ OrthancPluginRefreshMetricsCallback

typedef void(* OrthancPluginRefreshMetricsCallback) ()

Signature of a callback function that is called by Orthanc whenever a monitoring tool (such as Prometheus) asks the current values of the metrics. This callback gives the plugin a chance to update its metrics, by calling OrthancPluginSetMetricsValue() or OrthancPluginSetMetricsIntegerValue(). This is typically useful for metrics that are expensive to acquire.

See also: OrthancPluginRegisterRefreshMetrics()

◆ OrthancPluginStorageCreate

typedef OrthancPluginErrorCode(* OrthancPluginStorageCreate) (const char *uuid, const void *content, int64_t size, OrthancPluginContentType type)

Signature of a callback function that is triggered when Orthanc writes a file to the storage area.

Parameters

uuid	The UUID of the file.
content	The content of the file.
size	The size of the file.
type	The content type corresponding to this file.

Returns: 0 if success, other value if error.

◆ OrthancPluginStorageRead

typedef OrthancPluginErrorCode(* OrthancPluginStorageRead) (void **content, int64_t *size, const char *uuid, OrthancPluginContentType type)

Signature of a callback function that is triggered when Orthanc reads a file from the storage area.

Parameters

content	The content of the file (output).
size	The size of the file (output).
uuid	The UUID of the file of interest.
type	The content type corresponding to this file.

Returns: 0 if success, other value if error.

Deprecated:: New plugins should use OrthancPluginStorageRead2

Warning: The "content" buffer must have been allocated using the "malloc()" function of your C standard library (i.e. nor "new[]", neither a pointer to a buffer). The "free()" function of your C standard library will automatically be invoked on the "content" pointer.

◆ OrthancPluginStorageReadRange

typedef OrthancPluginErrorCode(* OrthancPluginStorageReadRange) (OrthancPluginMemoryBuffer64 *target, const char *uuid, OrthancPluginContentType type, uint64_t rangeStart)

Signature of a callback function that is triggered when Orthanc reads a portion of a file from the storage area. Orthanc indicates the start position and the length of the range.

Parameters

target	Memory buffer where to store the content of the range. The memory buffer is allocated and freed by Orthanc. The length of the range of interest corresponds to the size of this buffer.
uuid	The UUID of the file of interest.
type	The content type corresponding to this file.
rangeStart	Start position of the requested range in the file.

Returns: 0 if success, other value if error.

	)

This function checks whether the version of the Orthanc server running this plugin, is above the given version. Contrarily to OrthancPluginCheckVersion(), it is up to the developer of the plugin to make sure that all the Orthanc SDK services called by the plugin are actually implemented in the given version of Orthanc.

Parameters

context	The Orthanc plugin context, as received by OrthancPluginInitialize().
expectedMajor	Expected major version.
expectedMinor	Expected minor version.
expectedRevision	Expected revision.

Returns: 1 if and only if the versions are compatible. If the result is 0, the initialization of the plugin should fail.

◆ OrthancPluginRegisterOnChangeCallback()

void OrthancPluginRegisterOnChangeCallback	(	OrthancPluginContext *	context,
		OrthancPluginOnChangeCallback	callback
	)

This function registers a callback function that is called whenever a change happens to some DICOM resource.

Warning: Your callback function will be called synchronously with the core of Orthanc. This implies that deadlocks might emerge if you call other core primitives of Orthanc in your callback (such deadlocks are particularly visible in the presence of other plugins or Lua scripts). It is thus strongly advised to avoid any call to the REST API of Orthanc in the callback. If you have to call other primitives of Orthanc, you should make these calls in a separate thread, passing the pending events to be processed through a message queue.

Parameters

context	The Orthanc plugin context, as received by OrthancPluginInitialize().
callback	The callback function.

◆ OrthancPluginRegisterOnStoredInstanceCallback()

void OrthancPluginRegisterOnStoredInstanceCallback	(	OrthancPluginContext *	context,
		OrthancPluginOnStoredInstanceCallback	callback
	)

This function registers a callback function that is called whenever a new DICOM instance is stored into the Orthanc core.

Warning: Your callback function will be called synchronously with the core of Orthanc. This implies that deadlocks might emerge if you call other core primitives of Orthanc in your callback (such deadlocks are particularly visible in the presence of other plugins or Lua scripts). It is thus strongly advised to avoid any call to the REST API of Orthanc in the callback. If you have to call other primitives of Orthanc, you should make these calls in a separate thread, passing the pending events to be processed through a message queue.

Parameters

context	The Orthanc plugin context, as received by OrthancPluginInitialize().
callback	The callback function.

◆ OrthancPluginRegisterReceivedInstanceCallback()

OrthancPluginErrorCode OrthancPluginRegisterReceivedInstanceCallback	(	OrthancPluginContext *	context,
		OrthancPluginReceivedInstanceCallback	callback
	)

This function registers a custom callback to keep/discard/modify incoming DICOM instances received by Orthanc from any source (C-STORE or REST API).

Warning: Contrarily to OrthancPluginRegisterIncomingCStoreInstanceFilter() and OrthancPluginRegisterIncomingDicomInstanceFilter() that can be called by multiple plugins, OrthancPluginRegisterReceivedInstanceCallback() can only be used by one single plugin.

Parameters

context	The Orthanc plugin context, as received by OrthancPluginInitialize().
callback	The callback.

Returns: 0 if success, other value if error.

◆ OrthancPluginRegisterRefreshMetricsCallback()

See also: OrthancPluginRegisterRestCallbackNoLock()

Note: The regular expression is case sensitive and must follow the Perl syntax.

◆ OrthancPluginRegisterRestCallbackNoLock()

void OrthancPluginRegisterRestCallbackNoLock	(	OrthancPluginContext *	context,
		const char *	pathRegularExpression,
		OrthancPluginRestCallback	callback
	)

This function registers a REST callback against a regular expression for a URI. This function must be called during the initialization of the plugin, i.e. inside the OrthancPluginInitialize() public function.

Contrarily to OrthancPluginRegisterRestCallback(), the callback will NOT be invoked in mutual exclusion. This can be useful for high-performance plugins that must handle concurrent requests (Orthanc uses a pool of threads, one thread being assigned to each incoming HTTP request). Of course, if using this function, it is up to the plugin to implement the required locking mechanisms.

Parameters

context	The Orthanc plugin context, as received by OrthancPluginInitialize().
pathRegularExpression	Regular expression for the URI. May contain groups.
callback	The callback function to handle the REST call.

See also: OrthancPluginRegisterRestCallback()
