Detailed Description

This class defines loader class which is used with AdvCachedStorage.

Member Function Documentation

virtual AutoPtr<StorageLoader> Celartem::StorageLoader::duplicate ( ) const

pure virtual

Duplicate the instance.

virtual Time Celartem::StorageLoader::getLastUpdateTime ( ) const

pure virtual

This method returns the last update time of the file.

virtual uint64_t Celartem::StorageLoader::getSize ( ) const

pure virtual

Return the size of the storage.

Returns: The size of the storage.
If the size is not known, this method should return 0xffffffffffffffff.

virtual String Celartem::StorageLoader::getStorageId ( ) const

pure virtual

Return the identifier of the storage.

virtual StorageRange Celartem::StorageLoader::load	(	Storage *	inStorage,
		uint64_t	inPos,
		size_t	inSize
	)

pure virtual

Load a range of storage which contains the range specified by inPos and inSize.

Parameters

inStorage	Storage to written on.
inPos	The position of the storage range.
inSize	The size of the storage range.

virtual void Celartem::StorageLoader::setBufferingSize ( size_t inSize = 1024 )

pure virtual

Set the buffering size. The buffering size has very large impact on the networking performance.

Parameters

inSize Buffering size in bytes. The default is 1024 bytes.

virtual void Celartem::StorageLoader::setCallback	(	DuplicateStreamCallback	inCallback,
		void *	inContext
	)

pure virtual

Set the callback which is called when calls to load take long.

Parameters

inCallback	Pointer to a callback function.
inContext	Context for the callback function.
