Member Function Documentation

deserialize()

void Clone_Desc_Locator::deserialize	(	const byte *	desc_loc,
		uint	desc_len,
		Chunk_Info *	chunk_info
	)

Deserialize the descriptor.

Parameters

[in]	desc_loc	serialized locator
[in]	desc_len	locator length
[in,out]	chunk_info	chunk information

init()

void Clone_Desc_Locator::init	(	uint64_t	id,
		uint64_t	snap_id,
		Snapshot_State	state,
		uint	version,
		uint	index
	)

Initialize clone locator.

Parameters

[in]	id	Clone identifier
[in]	snap_id	Snapshot identifier
[in]	state	snapshot state
[in]	version	Descriptor version
[in]	index	clone index

match()

bool Clone_Desc_Locator::match

(

Clone_Desc_Locator *

other_desc

)

Check if the passed locator matches the current one.

Parameters

[in]

other_desc

input locator descriptor

Returns

true if matches

serialize()

void Clone_Desc_Locator::serialize	(	byte *&	desc_loc,
		uint &	len,
		Chunk_Info *	chunk_info,
		mem_heap_t *	heap
	)

Serialize the descriptor.

Caller should pass the length if allocated.

Parameters

[out]	desc_loc	serialized descriptor
[in,out]	len	length of serialized descriptor
[in]	chunk_info	chunk information to serialize
[in]	heap	heap for allocating memory
