Detailed Description

Low-level buffer object.

Constructor & Destructor Documentation

◆ NCollection_Buffer()

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::~NCollection_Buffer ( )

inline

Destructor.

Member Function Documentation

◆ Allocate()

bool NCollection_Buffer::Allocate ( const Standard_Size theSize )

inline

Allocate the buffer.

Parameters

theSize buffer length in bytes

◆ Allocator()

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

inline

Returns: buffer allocator

◆ ChangeData()

Standard_Byte* NCollection_Buffer::ChangeData ( )

inline

Returns: buffer data

◆ Data()

const Standard_Byte* NCollection_Buffer::Data ( ) const

inline

Returns: buffer data

virtual void NCollection_Buffer::DumpJson	(	Standard_OStream &	theOStream,
		Standard_Integer	theDepth = `-1`
	)		const

inlinevirtual

Dumps the content of me into the stream.

Reimplemented in Graphic3d_Buffer, Graphic3d_IndexBuffer, and Graphic3d_BoundBuffer.

◆ Free()

void NCollection_Buffer::Free ( )

inline

De-allocate buffer.

◆ IsEmpty()

inline

Assign new buffer allocator with de-allocation of buffer.

◆ Size()

Standard_Size NCollection_Buffer::Size ( void ) const

inline

Return buffer length in bytes.
