Member Function Documentation

getSymbolValue()

Expression RelativeCoordinatePositionerBase::ComponentScope::getSymbolValue ( const String & symbol ) const

overridevirtual

Returns the value of a symbol.

If the symbol is unknown, this can throw an Expression::EvaluationError exception. The member value is set to the part of the symbol that followed the dot, if there is one, e.g. for "foo.bar", symbol = "foo" and member = "bar".

Exceptions

Expression::EvaluationError

Reimplemented from Expression::Scope.

visitRelativeScope()

void RelativeCoordinatePositionerBase::ComponentScope::visitRelativeScope ( const String & scopeName, Visitor & visitor ) const

overridevirtual

Creates a Scope object for a named scope, and then calls a visitor to do some kind of processing with this new scope.

If the name is valid, this method must create a suitable (temporary) Scope object to represent it, and must call the Visitor::visit() method with this new scope.

Reimplemented from Expression::Scope.

getScopeUID()

String RelativeCoordinatePositionerBase::ComponentScope::getScopeUID ( ) const

overridevirtual

Returns some kind of globally unique ID that identifies this scope.

Reimplemented from Expression::Scope.
