Interface DoubleSupplierWithThrowable<E extends Throwable>

Type Parameters:

E - The extension

All Superinterfaces:

DoubleSupplier

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 DoubleSupplierWithThrowable<E extends Throwable>
extends DoubleSupplier

Generated from DoubleSupplier Extends java.util.function.DoubleSupplier to allow for a checked exception.

Method Detail

castDoubleSupplierWithThrowable

static <E extends Throwable> DoubleSupplierWithThrowable<E> castDoubleSupplierWithThrowable(DoubleSupplierWithThrowable<E> doublesupplierwiththrowable)

Utility method to mark lambdas of type DoubleSupplierWithThrowable

Type Parameters:

E - The type this interface is allowed to throw

Parameters:

doublesupplierwiththrowable - The interface instance

Returns:

the cast interface

aDoubleSupplierThatUnsafelyThrowsUnchecked

static <E extends Throwable> DoubleSupplier aDoubleSupplierThatUnsafelyThrowsUnchecked(DoubleSupplierWithThrowable<E> doublesupplierwiththrowable)
                                                                                throws E extends Throwable

Utility method to unwrap lambdas of type DoubleSupplier and withUncheckedThrowable any Exception

Type Parameters:

E - The type this interface is allowed to throw

Parameters:

doublesupplierwiththrowable - The interface instance

Returns:

the cast interface

Throws:

E - the original Exception from doublesupplierwiththrowable

E extends Throwable

asDoubleSupplierWithThrowable

static <E extends Throwable> DoubleSupplierWithThrowable<E> asDoubleSupplierWithThrowable(DoubleSupplier doublesupplier)

Utility method to convert DoubleSupplierWithThrowable

Type Parameters:

E - The type this interface is allowed to throw

Parameters:

doublesupplier - The interface instance

Returns:

the cast interface

getAsDouble

default double getAsDouble()

Overridden method of DoubleSupplierWithThrowable that will call getAsDoubleWithThrowable, but catching any exceptions.

Specified by:

getAsDouble in interface DoubleSupplier

Returns:

the value

getAsDoubleWithThrowable

double getAsDoubleWithThrowable()
                         throws E extends Throwable

Functional method that will throw exceptions.

Returns:

the value

Throws:

E - some exception

E extends Throwable

thatReturnsOnCatch

default DoubleSupplier thatReturnsOnCatch(double defaultReturnValue)

Parameters:

defaultReturnValue - A value to return if any throwable is caught.

Returns:

An interface that returns a default value if any exception occurs.

thatUnsafelyThrowsUnchecked

default DoubleSupplier thatUnsafelyThrowsUnchecked()
                                            throws E extends Throwable

Returns:

An interface that is only returned if no exception has been thrown.

Throws:

E - if an exception E has been thrown, it is rethrown by this method

E extends Throwable

An interface that will log exceptions on global logger

onException

default DoubleSupplierWithThrowable<E> onException(Consumer<Throwable> consumer)

Parameters:

consumer - An exception consumer.

Returns:

An interface that will log all exceptions to given logger
