Examples of org.eclipse.core.resources.IPathVariableManager

org.eclipse.core.resources.IPathVariableManager
Manages a collection of path variables and resolves paths containing a variable reference.
A path variable is a pair of non-null elements (name,value) where name is a case-sensitive string (containing only letters, digits and the underscore character, and not starting with a digit), and value is an absolute IPath object.

Path variables allow for the creation of relative paths whose exact location in the file system depends on the value of a variable. A variable reference may only appear as the first segment of a relative path.

This interface is not intended to be implemented by clients.
