Interface RandomOperator

All Superinterfaces:

Function<RandomVariable,RandomVariable>, UnaryOperator<RandomVariable>

Functional Interface:

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

Method Summary

Modifier and Type	Method and Description
default RandomOperator	andThen(RandomOperator after) Returns a composed function that first applies this function to its input, and then applies the after function to the result.
RandomVariable	apply(RandomVariable value) Applies this function to the given argument.
default RandomOperator	compose(RandomOperator before) Returns a composed function that first applies the before function to its input, and then applies this function to the result.
static RandomOperator	identity() Returns a function that always returns its input argument.

Method Detail

apply

RandomVariable apply(RandomVariable value)

Applies this function to the given argument.

Specified by:

apply in interface Function<RandomVariable,RandomVariable>

Parameters:

value - the function argument

Returns:

the function result

compose

default RandomOperator compose(RandomOperator before)

Returns a composed function that first applies the before function to its input, and then applies this function to the result. If evaluation of either function throws an exception, it is relayed to the caller of the composed function.

Parameters:

before - the function to apply before this function is applied

Returns:

a composed function that first applies the before function and then applies this function

Throws:

NullPointerException - if before is null

Function.andThen(Function)

andThen

default RandomOperator andThen(RandomOperator after)

Returns a composed function that first applies this function to its input, and then applies the after function to the result. If evaluation of either function throws an exception, it is relayed to the caller of the composed function.

Parameters:

after - the function to apply after this function is applied

Returns:

a composed function that first applies this function and then applies the after function

Throws:

NullPointerException - if after is null

See Also:

Function.compose(Function)

identity

static RandomOperator identity()

Returns a function that always returns its input argument.

Specified by:

identity in interface Function<RandomVariable,RandomVariable>

Specified by:

identity in interface UnaryOperator<RandomVariable>

Returns:

a function that always returns its input argument
