Method Detail

unit

public TimeUnit unit()

Returns the TimeUnit associated with this Delay.

Returns:

the time unit.

calculate

public abstract long calculate(long attempt)

This method is to be implemented by the child implementations and depending on the params that were set during construction time.

Parameters:

attempt - the attempt to calculate the delay from.

Returns:

the calculate delay.

fixed

                          TimeUnit unit)

Creates a new FixedDelay.

Parameters:

delay - the time of the delay.

unit - the unit of the delay.

Returns:

a created FixedDelay.
