Method Summary

Modifier and Type	Method	Description
default SerializableDoubleUnaryOperator	andThen(SerializableDoubleUnaryOperator after)	Returns a composed operator that first applies this operator to its input, and then applies the after operator to the result.
default SerializableDoubleUnaryOperator	compose(SerializableDoubleUnaryOperator before)	Returns a composed operator that first applies the before operator to its input, and then applies this operator to the result.
static SerializableDoubleUnaryOperator	identity()	Returns a unary operator that always returns its input argument.

Method Detail

compose

default SerializableDoubleUnaryOperator compose(SerializableDoubleUnaryOperator before)

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

Parameters:

before - the operator to apply before this operator is applied

Returns:

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

Throws:

java.lang.NullPointerException - if before is null

andThen(SerializableDoubleUnaryOperator)

andThen

default SerializableDoubleUnaryOperator andThen(SerializableDoubleUnaryOperator after)

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

Parameters:

after - the operator to apply after this operator is applied

Returns:

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

Throws:

java.lang.NullPointerException - if after is null

compose(SerializableDoubleUnaryOperator)

identity

static SerializableDoubleUnaryOperator identity()

Returns a unary operator that always returns its input argument.

Returns:

a unary operator that always returns its input argument
