Description copied from interface: Executor

Performs the executor's action on the given arguments in the given context. Typically, your custom executor will implement this method to provide its core functionality.

Specified by:

execute in interface Executor<ProcessExecutor.Result>

Overrides:

execute in class BatchExecutor

Parameters:

args - the arguments.

eval - the evaluator to use. Can frequently be null.

ctx - the context in which the execution occurs. Can frequently be null.

Returns:

the execution result.
