Package com.hazelcast.function

Interface FunctionEx<T,R>

Type Parameters:

T - the type of the input to the function

R - the type of the result of the function

All Superinterfaces:

Function<T,R>, com.hazelcast.security.impl.function.SecuredFunction, Serializable

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 FunctionEx<T,R>
extends Function<T,R>, Serializable, com.hazelcast.security.impl.function.SecuredFunction

Serializable variant of java.util.function.Function which declares checked exception.

Since:

4.0

Method Details

applyEx

R applyEx(T t)
   throws Exception

Exception-declaring version of Function.apply(T).

Throws:

Exception - in case of any exceptional case

apply

default R apply(T t)

Specified by:

apply in interface Function<T,R>

identity

static <T> FunctionEx<T,T> identity()

Serializable variant of java.util.function.Function#identity().

Type Parameters:

T - the type of the input and output objects to the function

unchecked

static <V,
R> FunctionEx<V,R> unchecked(FunctionEx<V,R> function)

Enforces that the return type is FunctionEx, to be used to wrap some expressions without casting.

compose

default <V> FunctionEx<V,R> compose(FunctionEx<? super V,? extends T> before)

Serializable variant of java.util.function.Function#compose(Function).

Type Parameters:

V - the type of input to the before function, and to the composed function

andThen

default <V> FunctionEx<T,V> andThen(FunctionEx<? super R,? extends V> after)

Serializable variant of java.util.function.Function#andThen(Function).

Type Parameters:

V - the type of output of the after function, and of the composed function
