Considerations for Object Constraints

Constraints for Object and Object list variables correspond to Java classes, whereas constraints for String variables correspond to simple types in XML schemas. When you apply constraints to Objects and perform validation, the data is validated as being of the specified Java class. For details on the Java classes you can apply to an Object or Object list, see Java Classes for Objects.

A constrained Object is validated when one of the following occur:

A service runs with the Validate input or Validate output check box selected on the Input/Output tab.

A service runs via the INVOKE step in a flow service with the Validate input or Validate output properties set on the INVOKE step.

The pub.schema:validate service runs.

A document is published. When this occurs, the contents of the document are validated against the specified document type.

During debugging, when you enter values for a constrained Object or Object list in the Input dialog box.

When you assign a value to an Object or Object list variable in the Pipeline view using

on the toolbar.
