Field Detail

asDo

public final Do<I> asDo

This chain, typed as a Do (sideeffect).

Method Detail

chain

public static <I,O> FnChain<I,O> chain(Fn<I,O> first)

then

public abstract <Y> FnChain<I,Y> then(Fn<? super O,Y> next)

Append a function to the chain.

Parameters:

next - The next function.

Returns:

the resulting new chain with the function appended.

then

public abstract FnChain<I,O> then(Do<? super O> sideeffect)

Append a Do (sideeffect) on the output from the last Fn in the chain. The chain may still be chained with further Fns or Dos. The chain yields the result from the last Fn as usual, after it has been passed to the given Do. If you need the resulting chain as a Do, use asDo.

Parameters:

sideeffect - The Do to apply on the output from the last Fn in the chain.

Returns:

The resulting new chain.
