Interface Closure<T>

  • Type Parameters:
    T - the type that the closure acts on
    All Known Implementing Classes:
    CatchAndRethrowClosure, ChainedClosure, ExceptionClosure, ForClosure, IfClosure, NOPClosure, SwitchClosure, TransformerClosure, WhileClosure
    Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

    public interface Closure<T>
    Defines a functor interface implemented by classes that do something.

    A Closure represents a block of code which is executed from inside some block, function or iteration. It operates an input object.

    Standard implementations of common closures are provided by ClosureUtils. These include method invocation and for/while loops.
