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 >.
