Constructor

Class: cogen.core.reactors.ReactorBase

A reactor just checks if there are ready-sockets for the operations. The operations are not done here, they are done in the socket ops instances.

Methods

__init__ (self, scheduler, resolution)

__len__ (self)

Returns number of waiting operations registered in the reactor.

add (self, op, coro)

Implemented by the child class that actualy implements the polling. Registers an operation.

handle_errored (self, desc, code=None)

Handles descriptors that have errors.

remove (self, op, coro)

Implemented by the child class that actualy implements the polling. Removes a operation.

run (self, timeout=0)

Implemented by the child class that actualy implements the polling. Calls the underlying OS polling mechanism and runs the operations for any ready descriptor.

run_once (self, fdesc, waiting_ops)

Run a operation, remove it from the reactor and return the result. Called from the main reactor loop.

run_operation (self, op, reactor=True)

Run the socket op and return result or exception.

run_or_add (self, op, coro)

Perform operation and return result or add the operation in the reactor if socket isn't ready and return none. Called from the scheduller via SocketOperation.process.

waiting_op (self, testcoro)
