## org.eclipse.birt.report.model.api.core
Class UserPropertyDefn

    java.lang.Object
      org.eclipse.birt.report.model.metadata.PropertyDefn
          org.eclipse.birt.report.model.metadata.ElementPropertyDefn
              org.eclipse.birt.report.model.api.core.UserPropertyDefn

All Implemented Interfaces:
  java.lang.Cloneable, IStructure, IElementPropertyDefn, IPropertyDefn, org.eclipse.birt.report.model.core.IPropertySet, org.eclipse.birt.report.model.metadata.IContainerDefn, org.eclipse.birt.report.model.validators.ISemanticTriggerDefnSetProvider

    public final class UserPropertyDefn

extends org.eclipse.birt.report.model.metadata.ElementPropertyDefn
implements IStructure

Represents a user-defined property. User-defined properties are created by the user and reside on elements. If element E has a user-defined property, and element C extends E, then element C also has all the user-defined properties defined on element E.

The user property definition implements the `IStructure` interface so that it can be accessed generically, and changes can be done though the command mechanism to allow undo/redo of style changes.
