Method Detail

fillSlice

public void fillSlice(BytesRef b,
                      long start,
                      int length)

Gets a slice out of PagedBytes starting at start with a given length. Iff the slice spans across a block border this method will allocate sufficient resources and copy the paged data.

Slices spanning more than two blocks are not supported.

fill

public void fill(BytesRef b,
                 long start)

Reads length as 1 or 2 byte vInt prefix, starting at start.

Note: this method does not support slices spanning across block borders.

ramBytesUsed

public long ramBytesUsed()

Returns approximate RAM bytes used
