and

default FailableIntPredicate<E> and(FailableIntPredicate<E> other)

Returns a composed FailableIntPredicate like IntPredicate.and(IntPredicate).

Parameters:

other - a predicate that will be logically-ANDed with this predicate.

Returns:

a composed FailableIntPredicate like IntPredicate.and(IntPredicate).

Throws:

NullPointerException - if other is null

negate

default FailableIntPredicate<E> negate()

Returns a predicate that negates this predicate.

Returns:

a predicate that negates this predicate.

or

default FailableIntPredicate<E> or(FailableIntPredicate<E> other)

Returns a composed FailableIntPredicate like IntPredicate.and(IntPredicate).

Parameters:

other - a predicate that will be logically-ORed with this predicate.

Returns:

a composed FailableIntPredicate like IntPredicate.and(IntPredicate).

Throws:

NullPointerException - if other is null

test

boolean test(int value)
      throws E

Tests the predicate.

Parameters:

value - the parameter for the predicate to accept.
