Interface IEditableContent

All Known Implementing Classes:

DocumentRangeNode, ResourceNode

public interface IEditableContent

Common interface for objects with editable contents. Typically it is implemented by objects that also implement the IStreamContentAccessor interface.

Clients may implement this interface.

Note that implementing IEditableContent does not automatically mean that it is editable. An object is only editable if it implements IEditableContent and the isEditable method returns true.
