Examples of org.eclipse.jface.text.ITypedRegion

org.eclipse.jface.text.ITypedRegion
Describes a region of an indexed text store such as a document or a string. The region consists of offset, length, and type. The region type is defined as a string.
A typed region can, e.g., be used to described document partitions.

Clients may implement this interface or use the standard implementation {@link org.eclipse.jface.text.TypedRegion}.
