Remarks

This class provides dynamic custom type information for model elements.

The Domain-Specific Language Tools (DSL Tools) use this type to represent the model elements in a domain model. This type controls how an element is handled by the property grid in the domain model and provides methods for working with the described element.

To create a customized element type descriptor, inherit from this class and override one or more of the members.

备注

If your DSL definition specifies a domain type descriptor for a domain class, then the generated code for the definition will contain a type descriptor, derived from ElementTypeDescriptor, specifically for that domain class. For more information, see Displaying Properties of Related Elements - redirection.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
