Method Detail

copy	back to summary
public Memoable copy() Implements org.bouncycastle.util.Memoable.copy. Doc from org.bouncycastle.util.Memoable.copy. Produce a copy of this object with its configuration and in its current state. The returned object may be used simply to store the state, or may be used as a similar object starting from the copied state.
