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:
    java.util.function.Function<T,​R>, com.hazelcast.security.impl.function.SecuredFunction, java.io.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 java.util.function.Function<T,​R>, java.io.Serializable, com.hazelcast.security.impl.function.SecuredFunction
    Serializable variant of java.util.function.Function which declares checked exception.
    Since:
    4.0
