Detailed Description

Used for resolving a RelativeCoordinate expression in the context of a component.

Member Function Documentation

evaluateFunction()

virtual double Expression::Scope::evaluateFunction ( const String &  functionName, const double *  parameters, int  numParameters  ) const

virtualinherited

Executes a named function.

If the function name is unknown, this can throw an Expression::EvaluationError exception.

Exceptions

Expression::EvaluationError

findSiblingComponent()

Component* RelativeCoordinatePositionerBase::ComponentScope::findSiblingComponent ( const String &  componentID ) const

protected

getScopeUID()

String RelativeCoordinatePositionerBase::ComponentScope::getScopeUID ( ) const

virtual

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

Reimplemented from Expression::Scope.

getSymbolValue()

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

virtual

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.

operator=()

ComponentScope& RelativeCoordinatePositionerBase::ComponentScope::operator= ( const ComponentScope &  )

delete

visitRelativeScope()

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

virtual

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.
