Constructor & Destructor Documentation

◆ DcmPolymorphOBOW()

DcmPolymorphOBOW::DcmPolymorphOBOW	(	const DcmTag &	tag,
		const Uint32	len = `0`
	)

constructor

Parameters

tag	attribute tag
len	length of the attribute value

Member Function Documentation

◆ clone()

virtual DcmObject* DcmPolymorphOBOW::clone ( ) const

inlinevirtual

clone method

Returns: deep copy of this object

Reimplemented from DcmOtherByteOtherWord.

Reimplemented in DcmPixelData, and DcmOverlayData.

◆ compare()

virtual int DcmPolymorphOBOW::compare ( const DcmElement & rhs ) const

virtual

Comparison operator that compares the normalized value of this element with a given element of the same type (e.g.

an DcmPolymorphOBOW with a DcmPolymorphOBOW). The tag of the element is also considered as the first component that is compared, followed by the object types (VR, i.e. DCMTK'S EVR). The DcmPolymorphOBOW implementation checks then whether the length of both elements are equal and if so continues comparing the values serialized to Little Endian using memcpy.

Parameters

rhs	the right hand side of the comparison

Returns: 0 if the object values are equal. -1 if this element has fewer components than the rhs element. Also -1 if the value of the first component that does not match is lower in this object than in rhs. Also returned if rhs cannot be casted to this object type or both objects are of different VR (i.e. the DcmEVR returned by the element's ident() call are different). 1 if either this element has more components than the rhs element, or if the first component that does not match is greater in this object than in rhs object.

Reimplemented from DcmOtherByteOtherWord.

Reimplemented in DcmPixelData.

◆ copyFrom()

virtual OFCondition DcmPolymorphOBOW::copyFrom ( const DcmObject & rhs )

virtual

Virtual object copying.

This method can be used for DcmObject and derived classes to get a deep copy of an object. Internally the assignment operator is called if the given DcmObject parameter is of the same type as "this" object instance. If not, an error is returned. This function permits copying an object by value in a virtual way which therefore is different to just calling the assignment operator of DcmElement which could result in slicing the object.

Parameters

rhs	- [in] The instance to copy from. Has to be of the same class type as "this" object

Returns: EC_Normal if copying was successful, error otherwise

Reimplemented from DcmOtherByteOtherWord.

Reimplemented in DcmPixelData, and DcmOverlayData.

◆ createUint16Array()

virtual OFCondition DcmPolymorphOBOW::createUint16Array	(	const Uint32	numWords,
		Uint16 *&	words
	)

virtual

create an empty Uint16 array of given number of words and set it.

All array elements are initialized with a value of 0 (using 'memzero'). This method is only applicable to OW data.

Parameters

numWords	number of words (16 bit) to be created
words	stores the pointer to the resulting buffer

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

Reimplemented from DcmOtherByteOtherWord.

Reimplemented in DcmPixelData.

◆ createUint8Array()

virtual OFCondition DcmPolymorphOBOW::createUint8Array	(	const Uint32	numBytes,
		Uint8 *&	bytes
	)

virtual

create an empty Uint8 array of given number of bytes and set it.

All array elements are initialized with a value of 0 (using 'memzero'). This method is only applicable to certain VRs, e.g. OB.

Parameters

numBytes	number of bytes (8 bit) to be created
bytes	stores the pointer to the resulting buffer

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

Reimplemented from DcmOtherByteOtherWord.

Reimplemented in DcmPixelData.

◆ getUint16Array()

virtual OFCondition DcmPolymorphOBOW::getUint16Array ( Uint16 *& val )

virtual

get a pointer to the element value of the current element as type Uint16.

Requires element to be of corresponding VR, otherwise an error is returned. This method does not copy, but returns a pointer to the element value, which remains under control of this object and is valid only until the next read, write or put operation.

Parameters

val	pointer to value returned in this parameter upon success

Returns: EC_Normal upon success, an error code otherwise

Reimplemented from DcmOtherByteOtherWord.

◆ getUint8Array()

virtual OFCondition DcmPolymorphOBOW::getUint8Array ( Uint8 *& val )

virtual

get a pointer to the element value of the current element as type string.

Requires element to be of corresponding VR, otherwise an error is returned. This method does not copy, but returns a pointer to the element value, which remains under control of this object and is valid only until the next read, write or put operation.

Parameters

val	pointer to value returned in this parameter upon success

Returns: EC_Normal upon success, an error code otherwise

Reimplemented from DcmOtherByteOtherWord.

◆ operator=()

DcmPolymorphOBOW& DcmPolymorphOBOW::operator= ( const DcmPolymorphOBOW & obj )

copy assignment operator

Parameters

obj	element to be copied

Returns: reference to this object

Referenced by DcmOverlayData::operator=().

replace the element value by a copy of the given Uint16 array (which is possibly multi-valued).

Requires element to be of corresponding VR, otherwise an error is returned.

Parameters

vals	new attribute value
num	number of values in array vals

Returns: EC_Normal upon success, an error code otherwise

Reimplemented from DcmOtherByteOtherWord.

Reimplemented in DcmPixelData.

◆ putUint8Array()

virtual OFCondition DcmPolymorphOBOW::putUint8Array	(	const Uint8 *	vals,
		const unsigned long	num
	)

virtual

replace the element value by a copy of the given Uint8 array (which is possibly multi-valued).

		const E_TransferSyntax	ixfer,
		const E_GrpLenEncoding	glenc,
		const Uint32	maxReadLength
	)

virtual

This function reads the data value of an attribute which is captured in the input stream and captures this information in this.

If not all information for an attribute could be read from the stream, the function returns EC_StreamNotifyClient. Note that if certain conditions are met, this function does not actually load the data value but creates and stores an object that enables us to load this information later.

Parameters

inStream	The stream which contains the information.
ixfer	The transfer syntax which was used to encode the information in inStream.
glenc	Encoding type for group length; specifies what will be done with group length tags.
maxReadLength	Maximum read length for reading an attribute value.

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

Reimplemented from DcmElement.

Reimplemented in DcmPixelData.

◆ transferEnd()

virtual void DcmPolymorphOBOW::transferEnd ( )

virtual

finalize the transfer state of this object.

This method must be called when reading/writing this object from/to a stream has been completed.

Reimplemented from DcmObject.

◆ transferInit()

virtual void DcmPolymorphOBOW::transferInit ( )

virtual

initialize the transfer state of this object.

This method must be called before this object is written to a stream or read (parsed) from a stream.

Reimplemented from DcmElement.

Reimplemented in DcmPixelData.

◆ write()

virtual OFCondition DcmPolymorphOBOW::write	(	DcmOutputStream &	outStream,
		const E_TransferSyntax	oxfer,
		const E_EncodingType	enctype,
		DcmWriteCache *	wcache
	)

virtual

This function writes this element's value to the outstream which was passed.

When writing information, the byte ordering (little or big endian) of the transfer syntax which was passed will be accounted for. In case the outstream does not provide enough space for all bytes of the current element's value, only a certain part of the value will be written to the stream. This element's transfer state indicates if the all bytes of value have already been written to the stream (ERW_ready), if the writing is still in progress and more bytes need to be written to the stream (ERW_inWork) or if the writing of the bytes of this element's value has not even begun yet (ERW_init). The member variable fTransferredBytes indicates how many bytes (starting from byte 0) of this element's value have already been written to the stream. This function will return EC_Normal, if the entire value of this element has been written to the stream, it will return EC_StreamNotifyClient, if there is no more space in the buffer and not all bytes of this element's value have been written, and it will return some other (error) value if there was an error.

Parameters

outStream	The stream the information will be written to.
oxfer	The transfer syntax which shall be used.
enctype	encoding types (undefined or explicit length) (actually unused)
wcache	pointer to write cache object, may be NULL

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

◆ writeSignatureFormat()

virtual OFCondition DcmPolymorphOBOW::writeSignatureFormat	(	DcmOutputStream &	outStream,
		const E_TransferSyntax	oxfer,
		const E_EncodingType	enctype,
		DcmWriteCache *	wcache
	)

virtual

special write method for creation of digital signatures

Parameters

outStream	DICOM output stream
oxfer	output transfer syntax
enctype	encoding types (undefined or explicit length)
wcache	pointer to write cache object, may be NULL

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