Detailed Description

the representation of a Print Management SCP.

This class implements most of the DIMSE behaviour of a DICOM Print SCP and uses Stored Print and Hardcopy Grayscale objects to store received print jobs in the local database.

Member Function Documentation

void DVPSPrintSCP::setDimseLogPath

(

const char *

fname

)

activates or deactivates dumping of the DIMSE communication in DICOM file format.

This method should be called prior to association negotiation with negotiateAssociation().

Parameters:

fname

full path name of the file into which a log of the DIMSE communication is written after association release. NULL disables the DICOM DIMSE dump completely.

DVPSAssociationNegotiationResult DVPSPrintSCP::negotiateAssociation

(

T_ASC_Network &

net

)

performs association negotiation for the Print SCP.

Depending on the configuration file settings, Basic Grayscale Print and Presentation LUT are accepted with all uncompressed transfer syntaxes. If association negotiation is unsuccessful, an A-ASSOCIATE-RQ is sent and the association is dropped. If successful, an A-ASSOCIATE-AC is prepared but not (yet) sent.

Parameters:

net

DIMSE network over which to receive the association request

Returns:

result indicating whether association negotiation was successful, unsuccessful or whether termination of the server was requested.

void DVPSPrintSCP::handleClient

(

)

confirms an association negotiated with negotiateAssociation() and handles all DIMSE communication for the Print SCP.

Returns after the association has been released or aborted.

int DVPSPrintSCP::errorCond	(	OFCondition	cond,
		const char *	message
	)			[private]

if the given condition indicates an error, prints the given string to the error log and returns true (nonzero), otherwise returns false.

Parameters:

	cond	condition to be checked
	message	to be printed, must not be NULL

Returns:

nonzero if cond indicates error, zero otherwise.

OFCondition DVPSPrintSCP::refuseAssociation

(

OFBool

isBadContext

)

[private]

sends A-ASSOCIATION-RQ as the result of an unsuccesful association negotiation.

Parameters:

isBadContext

defines the reason for the A-ASSOCIATE-RQ. true indicates an incorrect application context, false sends back an unspecified reject with no reason and is used when termination of the server application has been initiated.

Returns:

ASC_NORMAL if successful, an error code otherwise.

OFCondition DVPSPrintSCP::handleNGet	(	T_DIMSE_Message &	rq,
