Examples of KvpParser

org.geoserver.ows.KvpParser
Parses a key-value pair into a key-object pair.
This class is intended to be subclassed. Subclasses need declare the key in which they parse, and the type of object they parse into.

Instances need to be declared in a spring context like the following:
```
  <bean id="myKvpParser" class="org.xzy.MyKvpParser"/>  
```
Where com.xzy.MyKvpParser could be something like:
```
  public class MyKvpParser extends KvpParser { public MyKvpParser() { super( "MyKvp", MyObject.class )l } public Object parse( String value ) { return new MyObject( value ); } }  
```
Operation Binding
In the normal case, a kvp parser is engaged when a request specifies a name which matches the name declared by the kvp parser. It is also possible to attach a kvp parser so that it only engages on a particular operation. This is done by declaring the one or more of the following:
- service
- version
- request
When a kvp parser declares one or more of these properties, it will only be engaged if an incoming request specicfies matching values of the properties.

The following bean declaration would create the above kvp parser so that it only engages when the service is "MyService", and the request is "MyRequest".
```
  <bean id="myKvpParser" class="org.xzy.MyKvpParser"> <property name="service">MyService</property> <property name="request">MyRequest</property> <bean>  
```
