Interface LongSupplierWithThrowable<E extends Throwable>

Type Parameters:

E - The extension

All Superinterfaces:

LongSupplier

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 LongSupplierWithThrowable<E extends Throwable>
extends LongSupplier

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

Parameters:

longsupplierwiththrowable - The interface instance

Returns:

the cast interface

aLongSupplierThatUnsafelyThrowsUnchecked

static <E extends Throwable> LongSupplier aLongSupplierThatUnsafelyThrowsUnchecked(LongSupplierWithThrowable<E> longsupplierwiththrowable)
                                                                            throws E extends Throwable

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

Type Parameters:

E - The type this interface is allowed to throw

Parameters:

longsupplierwiththrowable - The interface instance

Returns:

the cast interface

Throws:

E - the original Exception from longsupplierwiththrowable

E extends Throwable

asLongSupplierWithThrowable

static <E extends Throwable> LongSupplierWithThrowable<E> asLongSupplierWithThrowable(LongSupplier longsupplier)

Utility method to convert LongSupplierWithThrowable

Type Parameters:

E - The type this interface is allowed to throw

Parameters:

longsupplier - The interface instance

Returns:

the cast interface

getAsLong

default long getAsLong()

Overridden method of LongSupplierWithThrowable that will call getAsLongWithThrowable, but catching any exceptions.

Specified by:

getAsLong in interface LongSupplier

Returns:

the value

getAsLongWithThrowable

long getAsLongWithThrowable()
                     throws E extends Throwable

the value

Throws:

E - some exception

E extends Throwable

thatReturnsOnCatch

default LongSupplier thatReturnsOnCatch(long 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
