Detailed Description

Objects of this kind are used to notify interior applications of changes provoked by an outer loop. They are handed to the application through Operator::notify() and it is up to the actual application how to handle them.

Event is organized as an extensible binary enumerator. Every class can add its own events using assign(). A typical code example is

class A
{
  static Event event;
};

Event A::event = Event::assign("Event for A");

Member Function Documentation

Event Algorithms::Event::assign ( const char *  name )

This function registers a new event type and assigns a unique identifier to it. The result of this function should be stored for later use.

)

Clear all flags

Definition at line 50 of file event.cc.

void Algorithms::Event::all

(

)

Set all flags

Definition at line 58 of file event.cc.

Event & Algorithms::Event::operator+= ( const Event &  event )

inline

Add the flags of the other event

Definition at line 235 of file event.h.

Event & Algorithms::Event::operator-= ( const Event &  event )

inline

Clear the flags of the other event

Definition at line 251 of file event.h.

bool Algorithms::Event::test ( const Event &  event ) const

inline

Test whether all the flags set in the other Event are also set in this one.

Definition at line 189 of file event.h.

bool Algorithms::Event::all_true

Sometimes, actions have to be taken by all means. Therefore, if this value is true, test() always returns true.
