Detailed Description

Low-level buffer object.

Constructor & Destructor Documentation

NCollection_Buffer::NCollection_Buffer ( const Handle< NCollection_BaseAllocator > &  theAlloc, const Standard_Size  theSize = 0, Standard_Byte *  theData = NULL  )

inline

Default constructor. When theData is NULL but theSize is not 0 than buffer of specified size will be allocated.

Parameters

theAlloc	memory allocator
theSize	buffer size
theData	buffer data allocated by theAlloc

NCollection_Buffer::~NCollection_Buffer ( )

inline

Destructor.

Member Function Documentation

bool NCollection_Buffer::Allocate ( const Standard_Size  theSize )

inline

Allocate the buffer.

Parameters

theSize

buffer length in bytes

const Handle< NCollection_BaseAllocator >& NCollection_Buffer::Allocator ( ) const

inline

Returns

buffer allocator

Standard_Byte* NCollection_Buffer::ChangeData ( )

inline

Returns

buffer data

const Standard_Byte* NCollection_Buffer::Data ( ) const

inline

Returns

buffer data

void NCollection_Buffer::Free ( )

inline

De-allocate buffer.

bool NCollection_Buffer::IsEmpty ( ) const

inline

Returns

true if buffer is not allocated

void NCollection_Buffer::SetAllocator ( const Handle< NCollection_BaseAllocator > &  theAlloc )

inline

Assign new buffer allocator with de-allocation of buffer.

Standard_Size NCollection_Buffer::Size ( void  ) const

inline

Return buffer length in bytes.
