Detailed Description

Accept or reject DcmItem objects by comparing a specific attribute to a set of values.

DcmAttributeFilter objects can be used to compare a specific attribute with one or more values - or to accept any DcmItem if no attribute is specified. DcmAttributeFilter objects can be used like any function taking a DcmItem& or a DcmFileFormat& object as parameter and returning a boolean value.

Constructor & Destructor Documentation

template<typename Iterator >

DcmAttributeFilter::DcmAttributeFilter	(	const DcmTagKey &	tag,
		const Iterator &	begin,
		const Iterator &	end
	)

inline

construct a DcmAttributeFilter object from two iterators defining the range of values.

Note: each value should be comparable with an object of type OFString.

Template Parameters

Iterator a type matching the STL's ForwardIterator concept.

Parameters

tag	a DcmTagKey object determining which attribute of a DcmItem should be compared with the range of values.
begin	an iterator referring to the first element in the range of values.
end	an iterator referring to one past the end in the range of values.

template<typename Container >

DcmAttributeFilter::DcmAttributeFilter	(	const DcmTagKey &	tag,
		const Container &	container
	)

inline

construct a DcmAttributeFilter object from a container containing the range of values.

Note: each value should be comparable with an object of type OFString.

Template Parameters

Container a class matching the STL's Container concept.

Parameters

tag	a DcmTagKey object determining which attribute of a DcmItem should be compared with the range of values.
container	a container containing the range of values.

DcmAttributeFilter::DcmAttributeFilter	(	const DcmTagKey &	tag,
		const OFString &	value
	)

construct a DcmAttributeFilter object that compares the attribute with one specific value.

Parameters

tag	a DcmTagKey object determining which attribute of a DcmItem should be compared with the value.
value	an OFString that is to be compared with the actual value stored in the DcmItem the filter is invoked on.

DcmAttributeFilter::DcmAttributeFilter	(	const DcmTagKey &	tag,
		const char *const	value
	)

construct a DcmAttributeFilter object that compares the attribute with one specific value.

Parameters

tag	a DcmTagKey object determining which attribute of a DcmItem should be compared with the value.
value	a character string that is to be compared with the actual value stored in the DcmItem the filter is invoked on.

Member Function Documentation

OFBool DcmAttributeFilter::apply ( DcmItem & item ) const

apply the filter on a DcmItem.

Parameters

item	a DcmItem the filter should accept or reject.

Returns: OFTrue if the filter accepts the item, OFFalse otherwise.

OFBool DcmAttributeFilter::apply ( DcmFileFormat & dcmfile ) const

apply the filter on a DICOM file (represented by a DcmFileFormat instance).

Parameters

dcmfile a DcmFileFormat object the filter should accept or reject.

Returns: OFTrue if the filter accepts the DICOM file, OFFalse otherwise.

template<typename Iterator >

static IteratorBasedFilter<Iterator>* DcmAttributeFilter::createIteratorBasedFilter	(	const Iterator &	begin,
		const Iterator &	end
	)

inlinestaticprivate

helper function to deduce the Iterator type from a container's begin() and end() method.

Template Parameters

Iterator a type matching the STL's ForwardIterator concept.

Parameters

begin	an iterator referring to the first element in the range of values.
end	an iterator referring to one past the end in the range of values.

Returns: a pointer to a newly created IteratorBasedFilter object.

OFBool DcmAttributeFilter::operator() ( DcmItem & item ) const

convenience function to enable using DcmAttributeFilter as a functor.

Parameters

item	a DcmItem the filter should accept or reject.

Returns: OFTrue if the filter accepts the item, OFFalse otherwise.

OFBool DcmAttributeFilter::operator() ( DcmFileFormat & dcmfile ) const

convenience function to enable using DcmAttributeFilter as a functor.

Parameters

dcmfile a DcmFileFormat object the filter should accept or reject.

Returns: OFTrue if the filter accepts the DICOM file, OFFalse otherwise.
