Method Details

identity

static <E extends Throwable>
FailableIntUnaryOperator<E> identity()

Returns a unary operator that always returns its input argument.

Type Parameters:

E - The kind of thrown exception or error.

Returns:

a unary operator that always returns its input argument

nop

static <E extends Throwable>
FailableIntUnaryOperator<E> nop()

Gets the NOP singleton.

E - The kind of thrown exception or error.

Returns:

The NOP singleton.

andThen

default FailableIntUnaryOperator<E> andThen(FailableIntUnaryOperator<E> after)

Returns a composed FailableDoubleUnaryOperator like IntUnaryOperator.andThen(IntUnaryOperator).

Parameters:

after - the operator to apply after this one.

Returns:

a composed FailableIntUnaryOperator like IntUnaryOperator.andThen(IntUnaryOperator).
