Examples of org.eclipse.core.resources.IStorage

org.eclipse.core.resources.IStorage
A storage object represents a set of bytes which can be accessed. These may be in the form of an IFile or IFileState or any other object supplied by user code. The main role of an IStorage is to provide a uniform API for access to, and presentation of, its content.
Storage objects implement the IAdaptable interface; extensions are managed by the platform's adapter manager.
Clients may implement this interface.
