putTo

public void putTo(com.google.common.hash.PrimitiveSink sink)

Description copied from interface: PrimitiveSinkable

Dump the state of this object into a PrimitiveSink (e.g., a Hasher) for the purpose of computing a strong hash. Equality contract: Equal objects must dump the equal data into the sink, non-equal objects must dump different data into the sink. Please see the interface documentation of PrimitiveSink for more details and caveats/traps.

Specified by:

putTo in interface PrimitiveSinkable

Parameters:

sink - the sink to dump the object state into.
