Interface IntUnaryOperator
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
Represents an operation on a single 
int-valued operand that produces
 an int-valued result.  This is the primitive type specialization of
 UnaryOperator for int.
 This is a functional interface
 whose functional method is applyAsInt(int).

Method SummaryModifier and TypeMethodDescriptiondefault IntUnaryOperatorandThen(IntUnaryOperator after) Returns a composed operator that first applies this operator to its input, and then applies theafteroperator to the result.intapplyAsInt(int operand) Applies this operator to the given operand.default IntUnaryOperatorcompose(IntUnaryOperator before) Returns a composed operator that first applies thebeforeoperator to its input, and then applies this operator to the result.static IntUnaryOperatoridentity()Returns a unary operator that always returns its input argument.

Method Details- 
applyAsIntint applyAsInt(int operand) Applies this operator to the given operand.- Parameters:
- operand- the operand
- Returns:
- the operator result
 
- 
composeReturns a composed operator that first applies thebeforeoperator 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 beforeoperator and then applies this operator
- Throws:
- NullPointerException- if before is null

andThenReturns a composed operator that first applies this operator to its input, and then applies theafteroperator 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 afteroperator
- Throws:
- NullPointerException- if after is null

identityReturns a unary operator that always returns its input argument.- Returns:
- a unary operator that always returns its input argument
