Specification

Direct Known Subclasses:

WFSStrategy, WMSSpecification

public abstract class Specification
extends Object

Provides support for the Open Web Service Specificaitons.

This class operates as a Factory creating request for Open Web Services.

The idea is that this class operates a Toolkit for all things assocated with an Open Web Service specification. The various objects produced by this toolkit are used as strategy objects for the top level AbstractOpenWebService subclass. Example:

• WebMapServer - uses a GetCapabilitiesRequest during version negotiation.

Both name and version information that may be checked against a GetCapabilities document during version negotiation.

Specific Open Web Service implementations can extend this interface to include details that are specific to their specification. Example: The Web Map Service specification includes more operations such as GetMap and GetFeatureInfo.

Q: Why are these not static?
A: Because we want to place new specifications into a data structure for WebMapServer to search through dynamically
