Represents an operation on a single long-valued operand that produces
a long-valued result. This is the primitive type specialization of
UnaryOperator for long.
This is a functional interface
whose functional method is applyAsLong(long).

Public Methods
public LongUnaryOperator andThen (LongUnaryOperator 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
afteroperator
Throws
| NullPointerException | if after is null |
|---|
See Also
public abstract long applyAsLong (long operand)
Applies this operator to the given operand.
Parameters
| operand | the operand |
|---|
Returns
- the operator result
public LongUnaryOperator compose (LongUnaryOperator 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
beforeoperator and then applies this operator
Throws
| NullPointerException | if before is null |
|---|

public static LongUnaryOperator identity ()
Returns a unary operator that always returns its input argument.
Returns
- a unary operator that always returns its input argument
