org.apache.oozie.fluentjob.api.action.PipesBuilder

All Implemented Interfaces:

Builder<Pipes>

@InterfaceAudience.Private
 @InterfaceStability.Unstable
public class PipesBuilder
extends Object
implements Builder<Pipes>

A builder class for Pipes. The properties of the builder can only be set once, an attempt to set them a second time will trigger an IllegalStateException. The properties that are lists are an exception to this rule, of course multiple elements can be added / removed. Builder instances can be used to build several elements, although properties already set cannot be changed after a call to build() either.
