This new version allocates only a single event 00045 // finder for each port for each type of event, e.g., pos(), neg(), and 00046 // value_change(). The event finder persists as long as the port does, 00047 // which is what the LRM dictates. Because only a single instance is 00048 // allocated for each event type per port there is not a potential 00049 // explosion of storage as was true in the 2.0.1/2.1 versions. 00050 // 00051 // Revision 1.6 2006/02/02 21:26:34 acg 00052 // Andy Goodrich: pulled out the check I just stuck into the 00053 // sc_event_finder::free_instances() method. It turns out the LRM says that 00054 // sc_event_finder instances are valid as long as the sc_module hierarchy is 00055 // valid, so we can't give the user a call to free the instances. 00056 // 00057 // Revision 1.5 2006/02/02 21:10:52 acg 00058 // Andy Goodrich: added check for end of elaboration to the static method 00059 // sc_event_finder::free_instances(). This will allow the method to be 00060 // made public if that is desired. 00061 // 00062 // Revision 1.4 2006/02/02 20:43:09 acg 00063 // Andy Goodrich: Added an existence linked list to sc_event_finder so that 00064 // the dynamically allocated instances can be freed after port binding 00065 // completes. This replaces the individual deletions in ~sc_bind_ef, as these 00066 // caused an exception if an sc_event_finder instance was used more than 00067 // once, due to a double freeing of the instance. 00068 // 00069 // Revision 1.3 2006/01/13 18:47:41 acg 00070 // Added $Log command so that CVS comments are reproduced in the source. 00071 // 00072 00073 #include "sysc/communication/sc_event_finder.h" 00074 00075 namespace sc_core { 00076 00077 // ---------------------------------------------------------------------------- 00078 // CLASS : sc_event_finder 00079 // 00080 // Event finder base class. 00081 // ---------------------------------------------------------------------------- 00082 00083 // error reporting 00084 00085 void 00086 sc_event_finder::report_error( const char* id, const char* add_msg ) const 00087 { 00088 char msg[BUFSIZ]; 00089 if( add_msg != 0 ) { 00090 std::sprintf( msg, "%s: port '%s' (%s)", 00091 add_msg, m_port.name(), m_port.kind() ); 00092 } else { 00093 std::sprintf( msg, "port '%s' (%s)", m_port.name(), m_port.kind() ); 00094 } 00095 SC_REPORT_ERROR( id, msg ); 00096 } 00097 00098 00099 // constructor 00100 00101 sc_event_finder::sc_event_finder( const sc_port_base& port_ ) 00102 : m_port( port_ ) 00103 { 00104 } 00105 00106 00107 // destructor (does nothing) 00108 00109 sc_event_finder::~sc_event_finder() 00110 {} 00111 00112 } // namespace sc_core 00113 00114 // Taf!
