Detailed Description

a class representing the DICOM file meta information header

Definition at line 53 of file dcmetinf.h.

Constructor & Destructor Documentation

DcmMetaInfo::DcmMetaInfo

(

const DcmMetaInfo &

old

)

copy constructor

Parameters

old	item to be copied

Member Function Documentation

virtual Uint32 DcmMetaInfo::calcElementLength ( const E_TransferSyntax  xfer, const E_EncodingType  enctype  )

virtual

calculate the length of this DICOM element when encoded with the given transfer syntax and the given encoding type for sequences.

For elements, the length includes the length of the tag, length field, VR field and the value itself, for items and sequences it returns the length of the complete item or sequence including delimitation tags if applicable. Never returns undefined length.

Parameters

xfer	transfer syntax for length calculation
enctype	sequence encoding type for length calculation

Returns

length of DICOM element

Reimplemented from DcmItem.

OFBool DcmMetaInfo::checkAndReadPreamble ( DcmInputStream &  inStream, E_TransferSyntax &  newxfer  )

private

check if the next 132 bytes in the input stream are a preamble followed by the DICOM "magic word" DICM.

If so, try to determine the transfer syntax of the meta-header and return in parameter newxfer. If not, reset stream to start position.

Parameters

inStream	input stream, should be at start position
newxfer	as input parameter contains the expected transfer syntax, as output parameter returns the real transfer syntax of the meta-header as determined heuristically

Returns

true if meta-header found and read, false otherwise

virtual DcmObject* DcmMetaInfo::clone ( ) const

inlinevirtual

clone method

Returns

deep copy of this object

Reimplemented from DcmItem.

Definition at line 80 of file dcmetinf.h.

References DcmMetaInfo().

virtual OFCondition DcmMetaInfo::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 DcmItem.

E_TransferSyntax DcmMetaInfo::getOriginalXfer

(

)

const

return the transfer syntax in which this dataset was originally read.

Returns

transfer syntax in which this dataset was originally read, EXS_Unknown if the dataset was created in memory

virtual DcmEVR DcmMetaInfo::ident ( ) const

virtual

get type identifier

Returns

type identifier of this class (EVR_item)

Reimplemented from DcmItem.

virtual

load object from a DICOM file

Parameters

fileName	name of the file to load
readXfer	transfer syntax used to read the data (auto detection if EXS_Unknown)
groupLength	flag, specifying how to handle the group length tags
maxReadLength	maximum number of bytes to be read for an element value. Element values with a larger size are not loaded until their value is retrieved (with getXXX()) or loadAllDataElements() is called.

Returns

status, EC_Normal if successful, an error code otherwise

OFBool DcmMetaInfo::nextTagIsMeta ( DcmInputStream &  inStream )

private

peeks into the input stream and checks whether the next element is group 0002, i.e.

belongs to the meta-header

Returns

true if next element is part of meta-header, false otherwise
