Constructor & Destructor Documentation
| BALL::Selector::Selector | ( | ) |
Default constructor.
| BALL::Selector::Selector | ( | const Selector & | selector | ) |
Copy constructor.

Member Function Documentation
| virtual void BALL::Selector::clear | ( | ) | [virtual] |
Clear method.
| const Expression& BALL::Selector::getExpression | ( | ) | const |
Return the expression.
| Size BALL::Selector::getNumberOfSelectedAtoms | ( | ) | const |
Return the number of atoms selected during the last application.
Return a list containing pointers to all selected Atoms
| virtual Processor::Result BALL::Selector::operator() | ( | Composite & | composite | ) | [virtual] |
Access operator. If the given Composite is an Atom and the current expression_ is fulfilled for that atom, select it by calling Composite::select .
Reimplemented from BALL::UnaryProcessor< Composite >.
| void BALL::Selector::setExpression | ( | const Expression & | expression | ) |
Define the expression.
| virtual bool BALL::Selector::start | ( | ) | [virtual] |
Processor start method. This method is needed to reset the internal counter for the number of selected atoms.
Reimplemented from BALL::UnaryProcessor< Composite >.
