Constraint Modeling Language (CML) includes components that cover high-level global configurations to specific data types and constraints.
See these topics for information on each core concept and the ways they work together.
CML supports single-line code comments with // and block comments with /* */.
Note
How CML Fits in the Product Configure Business API Pipeline
When you call the Product Configure Business API, the request runs through a fixed sequence of stages. The CML constraint engine is one stage in that sequence, and where it runs determines which data it can see.
Global Properties and Settings
Header-level declarations define the global properties and settings for a model, including constants, properties, and external values that set up the foundation of the CML code.
Variables are the properties or characteristics defined within a type. Variables can hold different types of data and can be calculated from other values.
In Constraint Modeling Language (CML), you define types to represent entities or objects in the model. Types are the foundational building blocks of CML. A type encapsulates the property, relationships, constraint, and rules for the entity.
Relationships in Constraint Modeling Language (CML) define how different product types are associated with each other, forming the structural hierarchy of a product bundle. Relationships are also referred to as ports.
Constraints enforce rules and conditions on types, variables, and relationships. Use constraints to define logical restrictions and ensure consistency within the model.
