public ByteArrayCacheable(byte[] buf)

Method Detail

heapSize

public long heapSize()

Specified by:

heapSize in interface HeapSize

Returns:

Approximate 'exclusive deep size' of implementing object. Includes count of payload and hosting object sizings.

Returns the length of the ByteBuffer required to serialized the object. If the object cannot be serialized, it should return 0.

Specified by:

getSerializedLength in interface Cacheable

Returns:

int length in bytes of the serialized form or 0 if the object cannot be cached.

serialize

public void serialize(java.nio.ByteBuffer destination)

Description copied from interface: Cacheable

Serializes its data into destination.

Specified by:

serialize in interface Cacheable

Parameters:

destination - Where to serialize to

getDeserializer

public CacheableDeserializer<Cacheable> getDeserializer()

Description copied from interface: Cacheable

Returns CacheableDeserializer instance which reconstructs original object from ByteBuffer.

Specified by:

getDeserializer in interface Cacheable

Returns:

CacheableDeserialzer instance.

getBlockType

public BlockType getBlockType()

Specified by:

getBlockType in interface Cacheable

Returns:

the block type of this cached HFile block
