Detailed Description

The feature descriptor datatype interface.

This interface is not defined.

Member Function Documentation

virtual const char* DriveEngine::IDescriptor::GetBuffer ( ) const

pure virtual

Gets the buffer of descriptor.

The buffer can be null. If it is null then it was not initialized.

Exception safety : No-throw guarantee. This member function never throws exceptions.

virtual Size DriveEngine::IDescriptor::GetBufferSize ( ) const

pure virtual

Gets the buffer size.

Exception safety : No-throw guarantee. This member function never throws exceptions.

virtual const char* DriveEngine::IDescriptor::GetType ( ) const

pure virtual

Gets the descriptor type.

The type is unknown at framework level. It is the responsability of developper to establish the type of descriptor.

Exception safety : No-throw guarantee. This member function never throws exceptions.

virtual void DriveEngine::IDescriptor::SetBuffer	(	const char *	content,
		Size	length
	)

pure virtual

Sets buffer.

The content of buffer can be of different formats. Actually the feature extractor and matching algorithmes must know the intern format of the buffer.

Exception safety : Strong exception safety. This member function throws exceptions.

Parameters

content	The content of buffer of descriptor.
length	The size of content.
