Description
The variable keeps a scalar value such as a double, int, or a string. The value can be either a constant or be defined by an expression. The expression can reference other symbols. The AcDbAssocVariable then has AcDbAssocValueDependencies on these referenced symbols. Conversely, there may be AcDbAssocValueDependencies on this variable to obtain the value of the variable.
The evaluate() method of the variable evaluates the expression using the current values of the referenced symbols and sets the evaluated value.
