Examples of org.eclipse.core.runtime.IPath.makeRelative()

org.eclipse.core.runtime.IPath.makeRelative()
Returns a relative path with the segments and device id of this path. Absolute paths start with a path separator and relative paths do not. If this path is relative, it is simply returned. @return the new path
