Method Detail

invoke

public abstract T invoke(ITimeBasedState state)

A callback to compute some value from a ITimeBasedState.

Ensure that this callback is thread-safe and does not close over any instances of objects that may cause problems with cloning, such as evaluators.

Parameters:

state - The state to compute values from.

Returns:

A value computed from the state.

@Nonnull
public static <T> ComputeValueFromState<T> of(@Nonnull
                                                        ComputeValueFromState.Function<T> f)

Create a delegate for the given interface. This can be used to create a delegate from a lambda expression.

Parameters:

f - The function which will be invoked.

Returns:

A new delegate that will invoke the given function.
