Interface Pre

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 Pre

Functional interface that represents code executed as a Block.pre() 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 Detail

pre

void pre()

Provides a callback to initialize state ONCE before the body gets executed. This is guaranteed to be called BEFORE the transaction manager scope opens. It will only be called once no matter whether the block iterates or whether there is a retry. By default this implementation does nothing. Override it in subclasses to get support.
