Method Summary

Methods

Modifier and Type	Method and Description
void	cleanup() This method is invoked at the end of the plugin lifecycle to allow implementations to cleanup after themselves (e.g.
PluginResult	execute() This method is invoked to perform the plugin operation's implementation.
void	setWorkflowExecutionContext(WorkflowExecutionContext pExecutionContext) This method is called to set the ExecutionContext for the plugin operation execution.
void	validate() This method is invoked to validate the preconditions of the plugin operation have been satisfied.

Method Detail

setWorkflowExecutionContext

void setWorkflowExecutionContext(WorkflowExecutionContext pExecutionContext)

This method is called to set the ExecutionContext for the plugin operation execution. Implementations should set the context as an instance variable for use throughout the plugin operation's execution lifecycle.

Parameters:

pExecutionContext - the workflow execution context

execute

PluginResult execute()
                     throws FlexCheckedException

This method is invoked to perform the plugin operation's implementation.

Returns:

the result of the plugin operation's execution

Throws:

FlexCheckedException - if any exception occurs during the execution of the plugin operation

validate

void validate()
              throws FlexCheckedException

This method is invoked to validate the preconditions of the plugin operation have been satisfied. Implementations should perform validations such as required properties being set, and throw a FlexCheckedException if the validation check fails. Implementors should also make an attempt to perform all validations and throw a single exception where possible, and avoid having users track down one validation issue per execution.

Throws:

FlexCheckedException - if the preconditions of the plugin operation are not met.

cleanup

void cleanup()

This method is invoked at the end of the plugin lifecycle to allow implementations to cleanup after themselves (e.g. delete temporary files, close connections, etc.). Note that this method is invoked in the finally clause surrounding the plugin execution. This allows the implementations to avoid wrapping try/catch/finally around operations for the purpose of cleanup. Since an exception can occur at various points, implementations must take precautions in performing the necessary null checking. Also note that any exceptions raised during the cleanup will be logged and ignored.
