Method Details

unsharedHeapSize

public long unsharedHeapSize()

Specified by:

unsharedHeapSize in interface IMeasurableMemory

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 Clustering<byte[]>

make

public static ArrayClustering make(byte[]... values)
