Method Detail

process

protected void process(java.nio.ByteBuffer bb)

Description copied from class: AbstractStreamingHashFunction.AbstractStreamingHasher

Processes the available bytes of the buffer (at most chunk bytes).

Specified by:

process in class AbstractStreamingHashFunction.AbstractStreamingHasher

processRemaining

protected void processRemaining(java.nio.ByteBuffer bb)

Description copied from class: AbstractStreamingHashFunction.AbstractStreamingHasher

This is invoked for the last bytes of the input, which are not enough to fill a whole chunk. The passed ByteBuffer is guaranteed to be non-empty.

This implementation simply pads with zeros and delegates to AbstractStreamingHashFunction.AbstractStreamingHasher.process(ByteBuffer).

Overrides:

processRemaining in class AbstractStreamingHashFunction.AbstractStreamingHasher

makeHash

public HashCode makeHash()

Specified by:

makeHash in class AbstractStreamingHashFunction.AbstractStreamingHasher
