Constructor & Destructor Documentation

BALL::Selector::Selector ( )

Default constructor.

BALL::Selector::Selector ( const Selector selector)

Copy constructor.

BALL::Selector::Selector ( const String expression_string)

Construct a Selector with a string. The selector's expression is set to expression_string.

virtual BALL::Selector::~Selector ( )
virtual

Destructor.

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.

std::list<Atom*>& BALL::Selector::getSelectedAtoms ( )

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 >.

Selector& BALL::Selector::operator= ( const Selector selector)

Assignment operator.

bool BALL::Selector::operator== ( const Selector selector) const

Equality.

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 >.
