If this is the case, OFTrue will be returned, else OFFalse.

Parameters:

calledApplicationEntityTitlev

The application entity title which shall be checked for support. Valid pointer expected.

Returns:

OFTrue, if the called application entity title is supported, OFFalse, if the called application entity title is not supported or it is not given.

unsigned long WlmFileSystemInteractionManager::DetermineMatchingRecords

(

DcmDataset *

searchMask

)

This function determines the records from the worklist files which match the given search mask and returns the number of matching records.

Also, this function will store the matching records in memory in the array member variable matchingRecords.

Parameters:

searchMask

- [in] The search mask.

Returns:

Number of matching records.

unsigned long WlmFileSystemInteractionManager::GetNumberOfSequenceItemsForMatchingRecord	(	DcmTagKey	sequenceTag,
		WlmSuperiorSequenceInfoType *	superiorSequenceArray,
		unsigned long	numOfSuperiorSequences,
		unsigned long	idx
	)

For the matching record that is identified through idx, this function returns the number of items that are contained in the sequence element that is referred to by sequenceTag.

In case this sequence element is itself contained in a certain item of another superior sequence, superiorSequenceArray contains information about where to find the correct sequence element.

Parameters:

	sequenceTag	The tag of the sequence element for which the number of items shall be determined.
	superiorSequenceArray	Array which contains information about superior sequence elements the given sequence element is contained in.
	numOfSuperiorSequences	The number of elements in the above array.
	idx	Identifies the record from which the number of sequence items shall be determined.

Returns:

The number of items that are contained in the sequence element that is referred to by sequenceTag and that can be found in sequence items which are specified in superiorSequenceArray.

void WlmFileSystemInteractionManager::GetAttributeValueForMatchingRecord	(	DcmTagKey	tag,
		WlmSuperiorSequenceInfoType *	superiorSequenceArray,
		unsigned long	numOfSuperiorSequences,
		unsigned long	idx,
		char *&	value
	)

This function determines an attribute value of a matching record and returns this value in a newly created string to the caller.

Parameters:

	tag	Attribute tag. Specifies which attribute's value shall be returned.
	superiorSequenceArray	Array which contains information about superior sequence elements the given element is contained in.
	numOfSuperiorSequences	The number of elements in the above array.
	idx	Identifies the record from which the attribute value shall be retrieved.
	value	Pointer to a newly created string that contains the requested value. If value was not found an emtpy string will be returned.

void WlmFileSystemInteractionManager::ClearMatchingRecords

(

)

This function frees the memory which was occupied by matchingRecords.

It shall be called when the matching records are no longer needed.
