NAME

POE::strict - strict mode for POE

DESCRIPTION

POE::strict acts a lot like the strict pragma in perl. It activates internal constraints that are not normally active. The runtime behavior of POE will be a lot more strict (duh) and potentially very loud if your code is in any way questionable as far as the POE core is concerned.

This module can be used as if it were POE itself. Suggested usage is the removal of all instances of use POE and replacing those with use POE::strict.

For example,

  use POE::strict qw(Component::Client::TCP);

behaves exactly like

  use POE qw(Component::Client::TCP);

(Yeah, yeah, the former is not as semantically nice as the latter. Blame #poe. They thought the functionality was a bonus and I agreed.)

The list of activated asserts is as follows:

POE::Kernel::ASSERT_EVENTS

Assert when dispatching events to nonexistent sessions

POE::Kernel::ASSERT_USAGE

Assert if internal parameters are wacky

POE::Session::ASSERT_STATES

Yell about receiving unknown events

CAVEATS

The constants defined by this module MUST be loaded before POE is. So if some other module calls use POE before POE::strict gets compiled, all is for naught. You'll probably get some nice redefine warnings and no strictness. At some point, these constants will be turned into something a little more runtime friendly. Until then, make sure POE::strict is what loads up POE.
