接口 FunctionWithThrowable<T,R,E extends Throwable>

类型参数:

T - some generic flag

R - some generic flag

E - The extension

所有超级接口:

Function<T,R>

函数接口:

这是一个函数接口, 因此可用作 lambda 表达式或方法引用的赋值目标。

@FunctionalInterface
public interface FunctionWithThrowable<T,R,E extends Throwable>
extends Function<T,R>

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

castFunctionWithThrowable

static <T,R,E extends Throwable> FunctionWithThrowable<T,R,E> castFunctionWithThrowable(FunctionWithThrowable<T,R,E> functionwiththrowable)

Utility method to mark lambdas of type FunctionWithThrowable

类型参数:

T - Generic that corresponds to the same generic on Function

R - Generic that corresponds to the same generic on Function

E - The type this interface is allowed to throw

参数:

functionwiththrowable - The interface instance

返回:

the cast interface

aFunctionThatUnsafelyThrowsUnchecked

static <T,R,E extends Throwable> Function<T,R> aFunctionThatUnsafelyThrowsUnchecked(FunctionWithThrowable<T,R,E> functionwiththrowable)
                                                                             throws E extends Throwable

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

类型参数:

T - Generic that corresponds to the same generic on Function

R - Generic that corresponds to the same generic on Function

E - The type this interface is allowed to throw

参数:

functionwiththrowable - The interface instance

返回:

the cast interface

抛出:

E - the original Exception from functionwiththrowable

E extends Throwable

asFunctionWithThrowable

static <T,R,E extends Throwable> FunctionWithThrowable<T,R,E> asFunctionWithThrowable(Function<T,R> function)

Utility method to convert FunctionWithThrowable

类型参数:

T - Generic that corresponds to the same generic on Function

R - Generic that corresponds to the same generic on Function

E - The type this interface is allowed to throw

参数:

function - The interface instance

返回:

the cast interface

apply

default R apply(T v1)

Overridden method of FunctionWithThrowable that will call applyWithThrowable, but catching any exceptions.

指定者:

apply 在接口中 Function<T,R>

参数:

v1 - parameter to overridden method

返回:

the value

applyWithThrowable

R applyWithThrowable(T v1)
              throws E extends Throwable

Functional method that will throw exceptions.

参数:

v1 - parameter to overridden method

返回:

the value

抛出:

E - some exception

E extends Throwable

thatReturnsOptional

default Function<T,Optional<R>> thatReturnsOptional()

返回:

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

thatReturnsOnCatch

default Function<T,R> thatReturnsOnCatch(R defaultReturnValue)

参数:

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

返回:

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

thatUnsafelyThrowsUnchecked

default Function<T,R> thatUnsafelyThrowsUnchecked()
                                           throws E extends Throwable

返回:

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

抛出:

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

E extends Throwable

onException

default FunctionWithThrowable<T,R,E> onException(Consumer<Throwable> consumer)

参数:

consumer - An exception consumer.

返回:

An interface that will log all exceptions to given logger

onException

default FunctionWithThrowable<T,R,E> onException(BiConsumer<Throwable,Object[]> consumer)

参数:

consumer - An exception consumer.

返回:

An interface that will log all exceptions to given logger
