   org.geoserver.ows.KvpRequestReader

All known Subclasses:   org.geoserver.ows.adapters.KvpRequestReaderAdapter,  org.geoserver.wfs.kvp.ReleaseLockKvpRequestReader,  org.geoserver.ows.MessageKvpRequestReader,  org.geoserver.ows.kvp.EMFKvpRequestReader,  org.geoserver.wms.kvp.GetMapKvpRequestReader,
KvpRequestReader
public class KvpRequestReader (Code)
Creates a request bean from a kvp set.

A request bean is an object which captures the parameters of an operation being requested to a service.

This class is intended to be subclassed in cases when the creation and initilization of a request bean cannot be created reflectivley.

The type of the request bean must be declared by the class. See KvpRequestReader.getRequestBean() .

Instances need to be declared in a spring context like the following:

 
 <bean id="myKvpRequestReader" class="org.geoserver.ows.KvpRequestReader">
 <constructor-arg value="com.xyz.MyRequestBean"/>
 </bean>
 
 
Where com.xyz.MyRequestBean is a simple java bean such as:
 
 public class MyRequestBean {
 public void setX( Object x ) {
 ...
 }
 public Object getX() {
 ...
 }
 }

Constructor Detail
KvpRequestReader
public KvpRequestReader(Class requestBean)(Code)
Creats the new kvp request reader.
Parameters:
  requestBean - The type of the request read, not null




Method Detail
createRequest
public Object createRequest() throws Exception(Code)
Creats a new instance of the request object.

Subclasses may with to override this method. The default implementation attempts to reflectivley create an instance of the request bean.

A new instance of the request.



equals
final public boolean equals(Object obj)(Code)
Equals override, equality is based on KvpRequestReader.getRequestBean()



getRequestBean
final public Class getRequestBean()(Code)
The class of the request bean.



hashCode
final public int hashCode()(Code)



read
public Object read(Object request, Map kvp, Map rawKvp) throws Exception(Code)
Reads the request from the set of kvp parameters.

Subclasses may wish to override this method. The default implementation uses java bean reflection to populate the request bean with parameters taken from the kvp map.

The "raw" (unparsed) kvp map is also made available.

This method may return a new instance of the request object, or the original passed in.


Parameters:
  request - The request instance.
Parameters:
  kvp - The kvp set, map of String,Object.
Parameters:
