Method Detail

createExecutable

public Executable createExecutable(Environment env)
                            throws TaskException

Description copied from interface: Task

Creates an executable object which will do the work of this task in the given Environment. This method should do all of the parameter processing and prepare an object which just executes. The idea is that any communication with the user related to the supplied parameter values can be done before the task starts to execute in earnest. Consequently, the returned Executable object ought not to make any reference to env, though this is not absolutely prohibited.

Specified by:

createExecutable in interface Task

Overrides:

createExecutable in class ConsumerTask

Parameters:

env - the environment in which the task will operate

Throws:

TaskException - if no executable can be created; this should usually be a UsageException or some subclass
