Scope Object Model Design

The Scope object contains Variables with a list of values that can be assigned to the variable and rules that define relationships between assigned variables.

The following diagram illustrates the structure of the Scope Object Model:

Figure 1.

• Scope is a class that contains two lists: a list of Variables and a list of Rules.
• Variable class is intended to store the variable definition.
• Named constant is intended to store the value definition. It contains the property name, value, and valuetype.
• Enum is the container for the list of Named constants.
• Rule is a container for an expression. The Rule has both a name and definition where the definition type is ExpressionBase.
• ExpressionBase is an object representation of a Boolean expression.
