Interface Enter

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 Enter

Functional interface that represents code executed as a Block.enter() method. This is equivalent to Runnable but is made separate so that when passed as a parameter the lambda will be easily distinguished. Casting a lambda to this type also will serve as useful documentation.

Method Summary

Method Detail

enter

void enter()

Provides a callback to execute user-defined logic at the top of the block body but before the block body is executed. This is guaranteed to be called AFTER the transaction manager scope opens but BEFORE the block body is entered. It will be called once per iteration of the block or once if the block is not iterating. It WILL be called on retry. By default this implementation does nothing. Override it in subclasses to get support.
