rc_driver_object_base Class Reference

#include <rc_driver_object.h>

Inheritance diagram for rc_driver_object_base:

Detailed Description

This class is the base class of a driver object.

It contains all the infrastructure necessary to cache the calls that have to be forwarded. There also is a handle to the process that represents the driver. A driver object normally uses an own process instance which performs the forwarding. In case of non-blocking drivers it is also possible to shares one static process among all other driver objects.

Member Typedef Documentation

typedef boost::function<void (void)> call_type [protected]

The type of the forwarded function object.

A forwarded function object is always of the form: void f(void).

Reimplemented in rc_driver_object_b< IF, false >, and rc_driver_object_b< IF, true >.

Definition at line 141 of file rc_driver_object.h.

typedef std::vector<write_call> write_call_vector [protected]

The type of the write call vector.

Reimplemented in rc_driver_object_b< IF, false >, and rc_driver_object_b< IF, true >.

Definition at line 151 of file rc_driver_object.h.

typedef std::vector<write_call>::iterator write_call_iterator [protected]

The type of the write call vector iterator.

Reimplemented in rc_driver_object_b< IF, false >, and rc_driver_object_b< IF, true >.

Member Function Documentation

void writer_method_proc ( ) [protected, virtual]

The writer method process.

Definition at line 105 of file rc_driver_object.cpp.

void writer_thread_proc ( ) [protected, virtual]

The writer thread process.

Definition at line 122 of file rc_driver_object.cpp.

void safe_event_notify ( sc_event & e ) [static, protected]

Notifies an event.

Parameters:

the event to be notified

Notifies an event. This method can be called irrespectively of the current active SystemC's simulation phase.

Note:: May even be called during the update phase.

Attention:: This function relies on a SystemC kernel that either notifies the event or throws an error if sc_event::notify() is called during the update phase. Another reaction will result in undefined behaviour.
