Method Detail

element

public static <I,E> Parser<Stream<I>,I,E> element(P1<E> e)

Returns a parser that produces an element from the stream if it is available and fails otherwise.

Parameters:

e - The error to fail with if no element is available.

Returns:

A parser that produces an element from the stream if it is available and fails otherwise.

element

public static <I,E> Parser<Stream<I>,I,E> element(E e)

Returns a parser that produces an element from the stream if it is available and fails otherwise.

Parameters:

e - The error to fail with if no element is available.

Returns:

A parser that produces an element from the stream if it is available and fails otherwise.

satisfy

public static <I,E> Parser<Stream<I>,I,E> satisfy(P1<E> missing,
                                  F<I,E> sat,
                                  F<I,java.lang.Boolean> f)

Returns a parser that produces an element from the stream that satisfies the given predicate, or fails.

Parameters:

missing - The error if no element is available.

sat - The error if the element does not satisfy the predicate.

f - The predicate that the element should satisfy.

Returns:

A parser that produces an element from the stream that satisfies the given predicate, or fails.

satisfy

public static <I,E> Parser<Stream<I>,I,E> satisfy(E missing,
                                  F<I,E> sat,
                                  F<I,java.lang.Boolean> f)

Returns a parser that produces an element from the stream that satisfies the given predicate, or fails.

Parameters:

missing - The error if no element is available.

sat - The error if the element does not satisfy the predicate.

f - The predicate that the element should satisfy.

Returns:

A parser that produces an element from the stream that satisfies the given predicate, or fails.
