| const |
|
virtual |
Executes a named function. If the function name is unknown, this can throw an Expression::EvaluationError exception.

◆ getScopeUID()
String juce::Expression::Scope::getScopeUID |
( |
| ) |
const |
|
virtual |
Returns some kind of globally unique ID that identifies this scope.

◆ getSymbolValue()
Expression juce::Expression::Scope::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".

◆ visitRelativeScope()
void juce::Expression::Scope::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.
