Crawler
|
|
=======
|
|
|
|
The agent uses Twisted's cooperative multitasking model.
|
|
|
|
Crawler is the base class for all derived crawlers like the filesystem crawler
|
|
and the mailcrawler. The SampleCrawler returns a deferred that already had a
|
|
callback being called, so it will return at once.
|
|
|
|
Returns a deferred that must be supplied with a callback method (and in
|
|
most cases also an errback method).
|
|
|
|
We create the sample crawler via the master's controller. The sample
|
|
controller provides a simple method for this purpose.
|
|
|
|
>>> controller = master.controllers[0]
|
|
>>> controller.createAgent('crawl.sample', 'crawler01')
|
|
|
|
In the next step we request the start of a job, again via the controller.
|
|
|
|
>>> controller.enterJob('sample', 'crawler01')
|
|
|
|
The job is not executed immediately - we have to hand over control to
|
|
the twisted reactor first.
|
|
|
|
>>> from cybertools.agent.tests import tester
|
|
>>> tester.iterate()
|
|
SampleCrawler is collecting.
