Class SafeWritableBuffer

  • All Implemented Interfaces:
    org.apache.datasketches.memory.BaseBuffer, org.apache.datasketches.memory.BaseState, org.apache.datasketches.memory.Buffer, org.apache.datasketches.memory.WritableBuffer
    public class SafeWritableBuffer
extends SafeWritableBase
implements org.apache.datasketches.memory.WritableBuffer
    Safety first! Don't trust something whose contents you locations to read and write stuff to, but need a Buffer or WritableBuffer? use this!

    Delegates everything to an underlying ByteBuffer so all read and write operations will have bounds checks built in rather than using 'unsafe'.
