      extended by org.deegree.ogcwebservices.wms.capabilities.LayerBoundingBox
All Implemented Interfaces:
Serializable, Envelope

public class LayerBoundingBox
extends EnvelopeImpl

Layers may have zero or more elements that are either stated explicitly or inherited from a parent Layer. Each BoundingBox states the bounding rectangle of the map data in a particular spatial reference system; the attribute SRS indicates which SRS applies. If the data area is shaped irregularly then the BoundingBox gives the minimum enclosing rectangle.The attributes minx, miny, maxx, maxy indicate the edges of the bounding box in units of the specified SRS. Optional resx and resy attributes indicate the spatial resolution of the data in those same units.

A Layer may have multiple BoundingBox element, but each one shall state a different SRS. A Layer inherits any BoundingBox values defined by its parents. A BoundingBox inherited from the parent Layer for a particular SRS is replaced by any declaration for the same SRS in the child Layer. A BoundingBox in the child for a new SRS not already declared by the parent is added to the list of bounding boxes for the child Layer. A single Layer element shall not contain more than one BoundingBox for the same SRS.
