Interface ToIntFunctionWithThrowable<T,E extends Throwable>

Type Parameters:

T - some generic flag

E - The extension

All Superinterfaces:

ToIntFunction<T>

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 ToIntFunctionWithThrowable<T,E extends Throwable>
extends ToIntFunction<T>

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

Method Detail

castToIntFunctionWithThrowable

static <T,E extends Throwable> ToIntFunctionWithThrowable<T,E> castToIntFunctionWithThrowable(ToIntFunctionWithThrowable<T,E> tointfunctionwiththrowable)

Utility method to mark lambdas of type ToIntFunctionWithThrowable

Type Parameters:

T - Generic that corresponds to the same generic on ToIntFunction

E - The type this interface is allowed to throw

Parameters:

tointfunctionwiththrowable - The interface instance

Returns:

the cast interface

aToIntFunctionThatUnsafelyThrowsUnchecked

static <T,E extends Throwable> ToIntFunction<T> aToIntFunctionThatUnsafelyThrowsUnchecked(ToIntFunctionWithThrowable<T,E> tointfunctionwiththrowable)
                                                                                   throws E extends Throwable

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

Type Parameters:

T - Generic that corresponds to the same generic on ToIntFunction

E - The type this interface is allowed to throw

Parameters:

tointfunctionwiththrowable - The interface instance

Returns:

the cast interface

Throws:

E - the original Exception from tointfunctionwiththrowable

E extends Throwable

asToIntFunctionWithThrowable

static <T,E extends Throwable> ToIntFunctionWithThrowable<T,E> asToIntFunctionWithThrowable(ToIntFunction<T> tointfunction)

Utility method to convert ToIntFunctionWithThrowable

Type Parameters:

T - Generic that corresponds to the same generic on ToIntFunction

E - The type this interface is allowed to throw

Parameters:

tointfunction - The interface instance

Returns:

the cast interface

applyAsInt

default int applyAsInt(T v1)

Overridden method of ToIntFunctionWithThrowable that will call applyAsIntWithThrowable, but catching any exceptions.

Specified by:

applyAsInt in interface ToIntFunction<T>

Parameters:

v1 - parameter to overridden method

Returns:

the value

applyAsIntWithThrowable

int applyAsIntWithThrowable(T v1)
                     throws E extends Throwable

Functional method that will throw exceptions.

Parameters:

v1 - parameter to overridden method

Returns:

the value

Throws:

E - some exception

E extends Throwable

thatReturnsOptional

default Function<T,OptionalInt> thatReturnsOptional()

Returns:

An interface that will wrap the result in an optional, and return an empty optional when an exception occurs.

thatReturnsOnCatch

default ToIntFunction<T> thatReturnsOnCatch(int 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 ToIntFunction<T> 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

withLogging
