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

org.eclipse.core.runtime.IPath.removeLastSegments()
Returns a copy of this path with the given number of segments removed from the end. The device id is preserved. The number must be greater or equal zero. If the count is zero, this path is returned.
If this path has a trailing separator, it will still have a trailing separator after the last segments are removed (assuming there are some segments left). If there is no trailing separator, the result will not have a trailing separator. If the number equals or exceeds the number of segments in this path, a path with no segments is returned.
@param count the number of segments to remove @return the new path
