Interface IOLongUnaryOperator

Functional Interface:

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

@FunctionalInterface
public interface IOLongUnaryOperator

Represents an operation on a single long-valued operand that produces a long-valued result. This is the primitive type specialization of IOUnaryOperator for long.

This interface is similar to LongUnaryOperator except that it is allowed to throw an IOException.

Method Details

applyAsLong

long applyAsLong(long operand)
          throws IOException

This method is the same as LongUnaryOperator.applyAsLong(long), but with a support for IOException.

Parameters:

operand - The operand.

Returns:

The operator result.

Throws:

IOException - if there is an I/O error performing the operation.

compose

default IOLongUnaryOperator compose(@Nonnull
 IOLongUnaryOperator before)
                             throws IOException

This method is the same as LongUnaryOperator.compose(LongUnaryOperator), but with a support for IOException.

Parameters:

before - The operator to apply before this operator is applied.

Returns:

A composed operator that applies the before operator first and then this operator.

Throws:

IOException - if there is an I/O error performing the operation.

andThen

default IOLongUnaryOperator andThen(@Nonnull
 IOLongUnaryOperator after)
                             throws IOException

This method is the same as LongUnaryOperator.andThen(LongUnaryOperator), but with a support for IOException.

Parameters:

after - The operator to apply after this operator is applied.

Returns:

A composed operator that applies this operator first and then the after operator.

Throws:

IOException - if there is an I/O error performing the operation.

• compose(IOLongUnaryOperator)

identity

static IOLongUnaryOperator identity()
                             throws IOException

This method is the same as LongUnaryOperator.identity(), but with a support for IOException.

Returns:

A unary operator that always returns its input argument.

Throws:

IOException - if there is an I/O error performing the operation.
