Member Function Documentation

virtual IXferBytes* IMemoryStreamData::GetXferBytes ( ) const

pure virtual

Return a pointer to the associated XferBytes object.

Returns

A pointer to the current XferBytes object, or nil.

virtual bool16 IMemoryStreamData::IsOwnedXferBytes ( ) const

pure virtual

Determine whether we are responsible for the lifetime of the current XferBytes object, if any.

Returns

kTrue if we are responsible, kFalse if we are not (or if there is no associated XferBytes object).

virtual void IMemoryStreamData::Set ( IXferBytes *  underlyingXferBytes, bool16  takeOwnership = kFalse  )

pure virtual

Set the stream's associated XferBytes object. If the XferBytes object was dynamically allocated, responsibility for its lifetime may be assigned to IMemoryStreamData.

Parameters

underlyingXferBytes	IN A pointer to the XferBytes object.
takeOwnership	IN kTrue if IMemoryStreamData should take ownership of the XferBytes object, kFalse if not.
