Constructor & Destructor Documentation

◆ DicomModifyBase() [1/2]

ml::DicomModifyBase::DicomModifyBase	(	DCMTree::TagId	tagId = `DCMTree::TagId()`,
		const std::string &	modStrVal = `""`
	)

Constructor setting the tag ID and the string value for modifications.

◆ DicomModifyBase() [2/2]

ml::DicomModifyBase::DicomModifyBase ( const DicomModifyBase & )

default

Default copy constructor.

◆ ~DicomModifyBase()

virtual ml::DicomModifyBase::~DicomModifyBase ( )

virtual

Virtual destructor.

Member Function Documentation

◆ addTag()

DCMTree::TagPtr ml::DicomModifyBase::addTag	(	DCMTree::TreePtr	dcmTree,
		std::string *	errStr = `nullptr`,
		bool	setValue = `true`,
		bool	splitValue = `false`
	)		const

Add the tag with ID getTagId() to tree dcmTree and value _modificationStringValue; requires a valid non nullptr dcmTree.

Parameters

dcmTree	The DICOM tree to which the tag shall be added.
errStr	If nullptr then potential errors will be posted as ML_PRINT_ERROR, otherwise the error description will be appended to *errStr.
setValue	If true then the value is set from the given string, otherwise no value is set.
splitValue	If true then the value is decomposed at backslashes, otherwise one value is set/added.

Returns: A null tag pointer on failure or the pointer to the created tag.

◆ applyModifications()

virtual std::string ml::DicomModifyBase::applyModifications	(	DCMTree::TreePtr	dcmTree,
		const FieldContainer *	treeInfos = `nullptr`
	)

virtual

Apply a change to the given dcmTree.

If this is overwritten in derived classes, this base class version should be called first, because it sets up tag values for subsequent operations.

Parameters

dcmTree The DICOM tree to be modified.

treeInfos

A FieldContainer which - if not nullptr - can contain additional user defined information fields about dcmTree. Special field values:

String field with name "modificationStringValueReplacement" replaces the value returned by getModificationStringValue() until applyModifications is called the next time or it is set again with set[TagIdAnd]ModificationStringValue().
String field with name "modificationTagIdReplacement" replaces the value returned by getTagId() until applyModifications is called the next time or it is set again with setTagId[AndModificationStringValue]().

Returns: An empty string on success, otherwise a cumulative descriptive string of all problems.

Reimplemented in ml::DicomModifyOrdinary, ml::DicomModifyOtherTagOperations, ml::DicomModifyPrivateAdd, ml::DicomModifyPrivateRemove, and ml::DicomModifySequence.

◆ getModificationStringValue()

const std::string & ml::DicomModifyBase::getModificationStringValue ( ) const

Returns the string which is used to manipulate tag value(s) (might be temporarily overridden by a "modificationStringValueReplacement" field in treeInfos parameter of applyModifications()).

◆ getModificationStringValueAsMLInt()

bool ml::DicomModifyBase::getModificationStringValueAsMLInt ( MLint & retVal ) const

If the modificationStringValue() can be interpreted as an integer value then true is returned and the string is converted to that integer and returned in retVal; otherwise false is returned and retVal is left unchanged.

The conversion is performed with bool StringConversion::readFromString(value, intVal);

◆ getTagId()

DCMTree::TagId ml::DicomModifyBase::getTagId ( ) const

Returns the id of the tag to be modified (might be temporarily overridden be a "modificationTagIdReplacement" field in treeInfos parameter of applyModifications()).

◆ getTagIfItExists()

DCMTree::TagPtr ml::DicomModifyBase::getTagIfItExists	(	DCMTree::TreePtr	dcmTree,
		std::string *	errStr = `nullptr`
	)		const

Parameters

dcmTree	The DCMTree in which the tag shall be searched; must be non nullptr.
errStr	If nullptr then potential errors will be posted as ML_PRINT_ERROR, otherwise the error description will be appended to *errStr.

Returns: the tag with currently given getTagId() if it exists, otherwise return nullptr without considering this as an error.

◆ operator=()

DicomModifyBase & ml::DicomModifyBase::operator= ( const DicomModifyBase & )

default

Default assignment operator.

◆ removeTag()

void ml::DicomModifyBase::removeTag ( DCMTree::TreePtr dcmTree ) const

Remove the tag with the ID getTagId() if it exists, otherwise do nothing; (if dcmTree member is nullptr the call is ignored).

Parameters

dcmTree The DICOM tree from which the tag shall be removed.

◆ setModificationStringValue()

void ml::DicomModifyBase::setModificationStringValue ( const std::string & modStrVal )

Set the string value to be used for the tag modification if not overridden by a treeInfos-"modificationStringValueReplacement" entry as described in applyModifications.

◆ setTagId() [1/2]

void ml::DicomModifyBase::setTagId ( const std::string & tagIdStr )

Set the id (as std::string) of the tag to be modified; invalid ids will cause an ML_ERROR_PRINT, empty strings shall be ignored by specification and will set an id (0000,0000).

◆ setTagId() [2/2]

void ml::DicomModifyBase::setTagId ( DCMTree::TagId tagId )

Set the id of the tag to be modified.

◆ setTagIdAndModificationStringValue()

void ml::DicomModifyBase::setTagIdAndModificationStringValue	(	DCMTree::TagId	tagId,
		const std::string &	modStrVal
	)

Calls setTagId(tagId) and setModificationStringValue(modStrVal).

◆ setTagValue()

void ml::DicomModifyBase::setTagValue	(	DCMTree::TreePtr	dcmTree,
		std::string *	errStr = `nullptr`,
		const DICOMTagTools::ValueModifyModes	modMode = `DICOMTagTools::Replace`,
		bool	splitValue = `false`
	)		const

Sets the value of tag with getTagId() in dcmTree with new value _modificationStringValue.

Requires a valid non nullptr dcmTree.

Parameters

dcmTree	The DICOM tree in which the tag value shall be set.
errStr	If nullptr then potential errors will be posted as ML_PRINT_ERROR, otherwise the error description will be appended to *errStr.
splitValue	If true then the value is decomposed at backslashes, otherwise one value is set/added.
modMode	The way how the tag value shall be modified.

◆ tagExists()

bool ml::DicomModifyBase::tagExists ( DCMTree::TreePtr dcmTree ) const

Parameters

dcmTree The DCMTree in which the tagId shall be searched (false is returned if dcmTree is nullptr).

Returns: true if dcmTree is valid and it contains a tag with ID getTagId(), otherwise false is returned.
