element

protected final java.nio.ByteBuffer element

Method Detail

size

public int size()

public java.nio.ByteBuffer get(int i)

withEOC

public Composite withEOC(Composite.EOC newEoc)

Specified by:

withEOC in interface Composite

Overrides:

withEOC in class AbstractComposite

toByteBuffer

public java.nio.ByteBuffer toByteBuffer()

Specified by:

toByteBuffer in interface Composite

Overrides:

toByteBuffer in class AbstractComposite

unsharedHeapSize

public long unsharedHeapSize()

Returns:

the amount of on-heap memory retained by the object that might be reclaimed if the object were reclaimed, i.e. it should try to exclude globally cached data where possible, or counting portions of arrays that are referenced by the object but used by other objects only (e.g. slabbed byte-buffers), etc.

copy

public Composite copy(CFMetaData cfm,
                      AbstractAllocator allocator)
