Interface OpExecutor

All Known Subinterfaces:

OpManager

All Known Implementing Classes:

DirectOpExecutor, EjbOpExecutor, OpManagerBean

public interface OpExecutor

Executes an Op in some context by either delegating the execution to some other OpExecutor (as in the EJB case), or by instantiating the appropriate CallExecutor and invoking the Op's internal _execute method itself. The executor will depend on the environment. In the default EJB setup, the EjbOpExecutor routes the Op to an EJB-bound OpExecutor (OpManagerBean) and that OpManagerBean uses a DirectOpExecutor to execute it within EJB.

public Op executeOp(Op op)
