Method Detail

excessHeapSizeExcludingData

public long excessHeapSizeExcludingData()

Specified by:

excessHeapSizeExcludingData in interface CellName

Overrides:

excessHeapSizeExcludingData in class SimpleSparseCellName

unsharedHeapSize

public long unsharedHeapSize()

Specified by:

unsharedHeapSize in interface IMeasurableMemory

Overrides:

unsharedHeapSize in class SimpleSparseCellName

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 CellName copy(CFMetaData cfm,
            AbstractAllocator allocator)

Specified by:

copy in interface CellName

Specified by:

copy in interface Composite

Overrides:

copy in class SimpleSparseCellName
