Method Detail

activate

public int activate(ExecutionContext context)
             throws WorkflowException

Activate the template node.

Parameters:: context - The execution context. This object provides access to the runtime context, including the template ID, template definition ID, workflow instance ID, event data, and various services related to workflow enactment.
Returns:: Indicates whether (and how) to continue subsequent processing. Must be ExecutionContext.CONTINUE or ExecutionContext.STOP.
Throws:: WorkflowException - if an error occurred during node activation.

fixup

public void fixup(com.bea.wlpi.evaluator.ExpressionParser parser)
           throws WorkflowException

The framework calls this method after parsing the template definition. This provides the plugin node with an opportunity to compile any expressions it has.

Parameters:: parser - The expression parser to use. N.B. This object is not thread-safe: plug-ins must not keep a reference to it. This parameter is provided for backwards compatibility only. Plug-ins should use the factory method Expression.getExpression(String) or one of its overloads to compile their expressions.
Throws:: WorkflowException - if any of the expressions are invalid.
