Detailed Description

Interface class for a Storage Service Class Provider (SCP).

This class supports C-STORE and C-ECHO messages as an SCP. The received datasets are always stored as DICOM files with the same Transfer Syntax as used for the network transmission. Both the generation of the directory structure and the filenames can be configured by the user.

Note: The current implementation always requires to load a so-called association negotiation profile from a configuration file, which specifies the list of Presentation Contexts (i.e. combination of SOP Class and Transfer Syntaxes) to be supported by this Storage SCP. If no association negotiation profile is loaded, the SCP will only support the Verification SOP Class (with Default Transfer Syntax, i.e. C-ECHO with Implicit VR Little Endian), which is required for all DICOM Service Class Providers.

◆ checkAndProcessSTORERequest()

virtual Uint16 DcmStorageSCP::checkAndProcessSTORERequest	(	const T_DIMSE_C_StoreRQ &	reqMessage,
		DcmFileFormat &	fileformat
	)

protectedvirtual

check the given C-STORE request and dataset for validity.

This method is called by handleIncomingCommand() before sending the response in order to determine the DIMSE status code to be used for the response message. If this check has been passed successfully, the received dataset is stored as a DICOM file.

Parameters

reqMessage	C-STORE request message data structure to be checked and processed
fileformat	DICOM fileformat structure containing the C-STORE request dataset to be checked and processed

Returns: DIMSE status code to be used for the C-STORE response

◆ generateDirAndFilename()

		OFString &	directoryName,
		OFString &	sopClassUID,
		OFString &	sopInstanceUID,
		DcmDataset *	dataset = `NULL`
	)

protectedvirtual

generate a directory and file name for a DICOM dataset that has been received.

The naming scheme can be specified by the methods setDirectoryGenerationMode(), setFilenameGenerationMode() and setFilenameExtension(). Please note that this method only generates the names but neither creates the directory structure nor the DICOM file.

Parameters

filename	reference to variable that will store the resulting filename
directoryName	reference to variable that will store the resulting directory name (including the main output directory)
sopClassUID	SOP Class UID of the DICOM object. This is both an input and output parameter. If an empty value is passed to this method, the value of the data element SOP Class UID (0008,0016) is determined from the DICOM dataset.
sopInstanceUID	SOP Instance UID of the DICOM object. This is both an input and output parameter. If an empty value is passed to this method, the value of the data element SOP Instance UID (0008,0018) is determined from the dataset.
dataset	pointer to dataset for which the directory and file name is to be generated (optional)

Returns: status, EC_Normal if successful, an error code otherwise

◆ generateSTORERequestFilename()

virtual OFCondition DcmStorageSCP::generateSTORERequestFilename	(	const T_DIMSE_C_StoreRQ &	reqMessage,
		OFString &	filename
	)

protectedvirtual

generate a directory and file name for a DICOM dataset that will be received.

The naming scheme can be specified by the methods setDirectoryGenerationMode(), setFilenameGenerationMode() and setFilenameExtension(). Please note that this method also creates the directory structure (if needed).

Parameters

reqMessage	C-STORE request message data structure used to generate the filename (depending on the specified options)
filename	reference to variable that will store the resulting filename

Returns: status, EC_Normal if successful, an error code otherwise

◆ getDatasetStorageMode()

E_DatasetStorageMode DcmStorageSCP::getDatasetStorageMode ( ) const

get the mode specifying whether and how to store the received datasets

Returns: current mode specifying whether and how to store the received datasets (see DcmStorageSCP::E_DatasetStorageMode)

◆ getDirectoryGenerationMode()

E_DirectoryGenerationMode DcmStorageSCP::getDirectoryGenerationMode ( ) const

get the mode for generating subdirectories used to store the received datasets

Returns: current mode for generating subdirectories (see DcmStorageSCP::E_DirectoryGenerationMode)

◆ getFilenameExtension()

get the filename extension that is appended to the generated filenames

Returns: current filename extension that is appended to the generated filenames

◆ getFilenameGenerationMode()

E_FilenameGenerationMode DcmStorageSCP::getFilenameGenerationMode ( ) const

get the mode for generating filenames for the received datasets

Returns: current mode for generating filenames (see DcmStorageSCP::E_FilenameGenerationMode)

◆ getOutputDirectory()

const OFString& DcmStorageSCP::getOutputDirectory ( ) const

get the output directory to be used for the storage of the received DICOM datasets.

Depending on the current mode for generating subdirectories (see getDirectoryGenerationMode()), further substructures are created automatically.

Returns: name of the output directory that is used for storing the received DICOM datasets

◆ handleIncomingCommand()

virtual OFCondition DcmStorageSCP::handleIncomingCommand	(	T_DIMSE_Message *	incomingMsg,
		const DcmPresentationContextInfo &	presInfo
	)

protectedvirtual

handler that is called for each incoming command message.

This handler supports C-ECHO and C-STORE requests. All other messages will be reported as an error. After a valid C-STORE request has been received, the request and associated dataset will be checked and further processed by checkAndProcessSTORERequest().

Parameters

incomingMsg	pointer to data structure containing the DIMSE message
presInfo	additional information on the Presentation Context used

Returns: status, EC_Normal if successful, an error code otherwise

Reimplemented from DcmSCP.

◆ loadAssociationConfiguration()

OFCondition DcmStorageSCP::loadAssociationConfiguration	(	const OFString &	filename,
		const OFString &	profile
	)

load an association negotiation profile from a configuration file.

This profile specifies which Presentation Contexts (i.e. combination of SOP Class and Transfer Syntaxes) are supported by this Storage SCP. If no association negotiation profile is loaded, the SCP will only support the Verification SOP Class (with Default Transfer Syntax, i.e. C-ECHO with Implicit VR Litte Endian), which is required for all DICOM Service Class Providers. The format and semantics of this configuration file are described in asconfig.txt file.

Parameters
