Method Detail

size

public int size()

Specified by:

size in interface Composite

Overrides:

size in class CompoundSparseCellName

get

public java.nio.ByteBuffer get(int i)

Specified by:

get in interface Composite

Overrides:

get in class CompoundSparseCellName

collectionElement

public java.nio.ByteBuffer collectionElement()

Description copied from interface: CellName

The value of the collection element, or null if the cell is not part of a collection (i.e. if !isCollectionCell()).

Specified by:

collectionElement in interface CellName

Overrides:

collectionElement in class CompoundSparseCellName

isCollectionCell

public boolean isCollectionCell()

Specified by:

isCollectionCell in interface CellName

Overrides:

isCollectionCell in class CompoundSparseCellName

copy

public CellName copy(CFMetaData cfm,
            AbstractAllocator allocator)

Specified by:

copy in interface CellName

Specified by:

copy in interface Composite

Overrides:

copy in class CompoundSparseCellName

unsharedHeapSize

public long unsharedHeapSize()

Specified by:

unsharedHeapSize in interface IMeasurableMemory

Overrides:

unsharedHeapSize in class CompoundSparseCellName

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.

unsharedHeapSizeExcludingData

public long unsharedHeapSizeExcludingData()

Specified by:

unsharedHeapSizeExcludingData in interface CellName

Overrides:

unsharedHeapSizeExcludingData in class CompoundSparseCellName
