OFCondition DVPSPrintMessageHandler::abortAssociation ( )

aborts the current association.

Returns:: a status code that can be checked with the SUCCESS() macro.

OFCondition DVPSPrintMessageHandler::actionRQ	(	const char *	sopclassUID,

sopinstanceUID	the requested SOP instance UID
actionTypeID	the action type ID
actionInformation	the action information dataset, may be NULL.
status	the response message status code is passed back in this parameter if the method returns with success status. Content is undefined otherwise.
actionReply	a pointer to the action reply dataset returned by the SCP is passed back in this parameter if the method returns with success status. Content is undefined otherwise. May return NULL if the SCP has not returned an attribute list. If a DICOM dataset is returned, it must be deleted by the caller.

Returns:: DIMSE_NORMAL if successful (e.g. no protocol failure), an error code otherwise.

status	the response message status code is passed back in this parameter if the method returns with success status. Content is undefined otherwise.
attributeListOut	a pointer to the attribute list returned by the SCP is passed back in this parameter if the method returns with success status. Content is undefined otherwise. May return NULL if the SCP has not returned an attribute list. If a DICOM dataset is returned, it must be deleted by the caller.

Parameters:

Returns:: DIMSE_NORMAL if successful (e.g. no protocol failure), an error code otherwise.

void DVPSPrintMessageHandler::dumpNMessage	(	T_DIMSE_Message &	msg,
		DcmItem *	dataset,

outgoing	OFTrue if message is outgoing, OFFalse if incoming.

T_ASC_PresentationContextID DVPSPrintMessageHandler::findAcceptedPC ( const char * sopclassuid ) [private]

looks for an accepted presentation context for the given SOP class.

If the SOP class is one of the Basic Grayscale Print Management Meta classes, looks for a presentation context for the meta SOP class.

Parameters:

sopclassuid SOP Class UID for which a presentation context is searched

Returns:: presentation context if found, 0 otherwise.

OFCondition DVPSPrintMessageHandler::getRQ	(	const char *	sopclassUID,
		const char *	sopinstanceUID,
		const Uint16 *	attributeIdentifierList,
		size_t	numShorts,
		Uint16 &	status,
		DcmDataset *&	attributeListOut
	)

sends an N-GET-RQ message and receives response.

Any event report requests incoming before the expected response message are handled.

Parameters:

sopclassUID	the requested SOP class UID, must be one of the supported print classes.
sopinstanceUID	the requested SOP instance UID
attributeIdentifierList	the list of DICOM attributes to get, may be NULL. The attributes should be coded in pairs along the array (e.g. {g,e,g,e,g,e,...}).
numShorts	the number of Uint16 values in the array (not the number of pairs).
status	the response message status code is passed back in this parameter if the method returns with success status. Content is undefined otherwise.
attributeListOut	a pointer to the attribute list returned by the SCP is passed back in this parameter if the method returns with success status. Content is undefined otherwise. May return NULL if the SCP has not returned an attribute list. If a DICOM dataset is returned, it must be deleted by the caller.

Returns:: DIMSE_NORMAL if successful (e.g. no protocol failure), an error code otherwise.

opens a DICOM association to a remote printer.

The Basic Grayscale Print Management Meta SOP Class and Presentation LUT SOP Class are requested. The association is only accepted if the remote printer supports at least the Basic Grayscale Print Management Meta SOP Class.

Parameters:

sends a DIMSE-N request (any type except N-EVENT-REPORT) and waits for a response.

Any event report requests incoming before the expected DIMSE-N-RSP are handled. If an event handler is registered, it is called for each received event report request.

Parameters:

presId	presentation context ID
request	DIMSE-N request message to be sent. All fields except DataSetType must be filled in.
rqDataSet	DICOM dataset to be sent with the request message, e.g. N-Set modification list, N-Action action information, or N-Create attribute list. Not applicable to N-Get or N-Delete.
response	the received response is passed back in this parameter if the method returns with success status. Content is undefined otherwise.
statusDetail	the status detail dataset of the received response is passed back in this parameter if the method returns with success status. Content is undefined otherwise.
rspDataset	the received response dataset is passed back in this parameter if the method returns with success status. Content is undefined otherwise.

Returns:: DIMSE_NORMAL if successful, an error code otherwise.

void DVPSPrintMessageHandler::setEventHandler ( DVPSPrintEventHandler * handler ) [inline]

registers an event handler object for incoming N-EVENT-REPORTs.

handler pointer to the new handler object. May be NULL.

OFCondition DVPSPrintMessageHandler::setRQ	(	const char *	sopclassUID,
		const char *	sopinstanceUID,
		DcmDataset *	modificationList,
		Uint16 &	status,
		DcmDataset *&	attributeListOut

sopclassUID	the requested SOP class UID, must be one of the supported print classes.
sopinstanceUID	the requested SOP instance UID
modificationList	the modification list dataset, must not be NULL.
status	the response message status code is passed back in this parameter if the method returns with success status. Content is undefined otherwise.
attributeListOut	a pointer to the attribute list returned by the SCP is passed back in this parameter if the method returns with success status. Content is undefined otherwise. May return NULL if the SCP has not returned an attribute list. If a DICOM dataset is returned, it must be deleted by the caller.
