Interface Action.Continuation<R,S,M,O>

Type Parameters:

R - the input type of parsing results

S - the output type of parsing results

M - the type of diagnostic messages

O - the type of obstructions to continuation

All Superinterfaces:

Function<R,Action<S,M,O>>

All Known Implementing Classes:

Parser, Update

Enclosing class:

Action<R,M,O>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public static interface Action.Continuation<R,S,M,O>
extends Function<R,Action<S,M,O>>

Functional interface for continuations.

Method Summary

Modifier and Type	Method and Description
default Action<S,M,O>	apply(R arg) Applies this continuation, ignoring any recyclable leaf node.
Action<S,M,O>	apply(R arg, Success<?,M,O> recyclable) Applies this continuation, possibly using a recyclable leaf node.
static <R,S,M,O> Action.Continuation<R,S,M,O>	forget(Function<? super R,? extends Action<S,M,O>> fun) Lifts a monadic function on parsing results to a continuation.
static <R,S,M,O> Action.Continuation<R,S,M,O>	map(Function<? super R,? extends S> fun) Lifts a function on parsing results to a monadic continuation.

Method Detail

apply

Action<S,M,O> apply(R arg,
                    Success<?,M,O> recyclable)

Applies this continuation, possibly using a recyclable leaf node.

Parameters:

arg - the input parsing result

recyclable - a recyclable leaf node, or null if not available

Returns:

a leaf node with a newly computed parsing result; either recyclable if available or new.

Action.succeed(Object, Success)

apply

default Action<S,M,O> apply(R arg)

Applies this continuation, ignoring any recyclable leaf node.

Specified by:

apply in interface Function<R,Action<S,M,O>>

Parameters:

arg - the input parsing result

Returns:

a leaf node with a newly computed parsing result

forget

static <R,S,M,O> Action.Continuation<R,S,M,O> forget(Function<? super R,? extends Action<S,M,O>> fun)

Lifts a monadic function on parsing results to a continuation.

Parameters:

fun - the function

Returns:

a continuation that applies the function

Throws:

IllegalArgumentException - if fun == null

map

static <R,S,M,O> Action.Continuation<R,S,M,O> map(Function<? super R,? extends S> fun)

Lifts a function on parsing results to a monadic continuation.

Parameters:

fun - the function

Returns:

a continuation that applies the function

Throws:

IllegalArgumentException - if fun == null
