Detailed Description

This class is a light wrapper for a couple of plain old data structures, so that they can be utilized in a MetaDataDictionary.

The class is designed to be intialized from a chuck of bytes that are read in from a file. Verification is performed to ensure that the bytes appear to be the correct format for the headers.

The POD structures a publicly avaible without access methods.

This code was contributed in the Insight Journal paper: "A Streaming IO Base Class and Support for Streaming the MRC and VTK File Format" by Lowekamp B., Chen D. http://www.insight-journal.org/browse/publication/729 https://hdl.handle.net/10380/3171

Member Function Documentation

virtual::itk::LightObject::Pointer itk::MRCHeaderObject::CreateAnother ( ) const

virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::LightObject.

void itk::MRCHeaderObject::DeepCopy

(

ConstPointer

h

)

SizeValueType itk::MRCHeaderObject::GetExtendedHeaderSize

(

)

const

the expected number of bytes in the extended header, this is only valid after a successful call to SetHeader.

const Header& itk::MRCHeaderObject::GetHeader

(

)

const

SizeValueType itk::MRCHeaderObject::GetHeaderSize ( ) const

inline

the expected number of bytes in the header

Definition at line 274 of file itkMRCHeaderObject.h.

virtual const char* itk::MRCHeaderObject::GetNameOfClass ( ) const

virtual

Run-time type information (and related methods).

Reimplemented from itk::LightObject.

bool itk::MRCHeaderObject::IsOriginalHeaderBigEndian

(

)

const

returns true if the original header from SetHeader was big endian.

static Pointer itk::MRCHeaderObject::New ( )

static

Method for creation through the object factory.

void itk::MRCHeaderObject::PrintSelf ( std::ostream &  os, Indent  indent  ) const

overrideprotectedvirtual

Prints loads of information from the header

Reimplemented from itk::LightObject.

bool itk::MRCHeaderObject::SetExtendedHeader

(

const void *

buffer

)

After SetHeader is called GetExtendedHeaderSize contains the extected size of the buffer argument. This buffer is expected to be the bytes which follow the header in the file.

The return value indicates if the extended header buffer is valid and known. If false is returned then extended header information is not available.

bool itk::MRCHeaderObject::SetHeader

(

const Header *

buffer

)

Parameters

buffer

is assumed to point to a 1024 block of memory which has the header

The return value indicates if buffer appears valid. If false is returned then the header member varible is in an undefined state.

If the byte order of the header then byte swapping will be performed.

void itk::MRCHeaderObject::swapHeader ( bool  bigEndian )

protected

Methods to fix the order of a set header
