public DoubleUnaryOperatorChainer(ThrowingDoubleUnaryOperator throwing)

Method Detail

doApplyAsDouble

public double doApplyAsDouble(double operand)
                       throws Throwable

Specified by:

doApplyAsDouble in interface ThrowingDoubleUnaryOperator

Throws:

Throwable

orTryWith

public DoubleUnaryOperatorChainer orTryWith(ThrowingDoubleUnaryOperator other)

Description copied from class: Chainer

Try with another throwing instance if the first instance fails

Specified by:

orTryWith in class Chainer<DoubleUnaryOperator,ThrowingDoubleUnaryOperator,DoubleUnaryOperatorChainer>

Parameters:

other - the other throwing instance

Returns:

a new chain

orThrow

public <E extends RuntimeException> ThrowingDoubleUnaryOperator orThrow(Class<E> exclass)

Description copied from class: Chainer

Rethrow the exception using a custom (unchecked!) exception class if this throwing instance fails

Your custom exception class must have a constructor accepting a single Throwable as an argument.

The original exception thrown will be the cause of the generated exception.

All instances of Error or RuntimeException thrown by the instance are thrown as is.

Specified by:

orThrow in class Chainer<DoubleUnaryOperator,ThrowingDoubleUnaryOperator,DoubleUnaryOperatorChainer>

Type Parameters:

E - type parameter of the exception class

Parameters:

exclass - the exception class

Returns:

a throwing instance

fallbackTo

public DoubleUnaryOperator fallbackTo(DoubleUnaryOperator fallback)

Description copied from class: Chainer

Fall back to a non throwing instance if this instance fails

Specified by:

fallbackTo in class Chainer<DoubleUnaryOperator,ThrowingDoubleUnaryOperator,DoubleUnaryOperatorChainer>

Parameters:

fallback - the fallback instance

Returns:

a non throwing instance

sneakyThrow

public DoubleUnaryOperator sneakyThrow()

Description copied from class: Chainer

Sneaky throw of the exception thrown by the instance

This code was inspited by the Lombok project.

Specified by:

sneakyThrow in class Chainer<DoubleUnaryOperator,ThrowingDoubleUnaryOperator,DoubleUnaryOperatorChainer>

orReturn

public DoubleUnaryOperator orReturn(double retval)

orReturnSelf

public DoubleUnaryOperator orReturnSelf()
