Member Function Documentation

virtual AutoPtr<StorageLoader> Celartem::StorageLoader::duplicate

(

)

const [pure virtual]

Duplicate the instance.

Returns:

The newly created StorageLoader instance.

virtual Time Celartem::StorageLoader::getLastUpdateTime

(

)

const [pure virtual]

This method returns the last update time of the file.

Returns:

The last update time.

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.

Returns:

The identifier (usually an URI).

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.

Returns:

The range actually loaded by this call.

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.
