Interface State

All Superinterfaces:

Comparable<State>

All Known Implementing Classes:

NdnChronoState

public interface State
extends Comparable<State>

An object representing a value in time. States are matchable (see matches(State)) so that we can determine which states can be compared against each other; states are comparable so that we can determine which instance is the latest/newest/greatest (and likely should be retained).

Method Detail

matches

boolean matches(State other)

Check if a state matches another state. States may change over time: e.g. the state of a counter may increment by one. In this case, we want to understand that the new state instance (e.g. counter == 1) matches the previous one (e.g. counter == 0) and should replace it. The same Java instance may be used for both states and this method then must return true.

Parameters:

other - another state

Returns:

true if the states match

toBytes

byte[] toBytes()

Returns:

the bytes representing this state
