Method Summary

protected OGCWebServiceResponse[]	createResponse(java.util.HashMap map, java.lang.String[] affectedFeatureTypes) create a response object from the GMLFeatureCollections store into the submitted HashMap
protected java.lang.String[]	getAffectedFeatureTypes(WFSQuery[] queries) return the names of the feature types affected by a Query
protected java.lang.String	getAffectedFields(java.lang.String table, FeatureType ft, WFSQuery query) the method returns a comma-seperated list of fields, that are affected by a WFSQuery against the subbmitted table.
private java.lang.String	getTableName(FeatureType ft, java.lang.String prop) extracts the table name from a property. it is assumed that the property name is constructed like this: table.propertyname or schema.table.propertyname.

Method Detail

getAffectedFeatureTypes

protected java.lang.String[] getAffectedFeatureTypes(WFSQuery[] queries)

return the names of the feature types affected by a Query

getAffectedFields

protected java.lang.String getAffectedFields(java.lang.String table,
                                             FeatureType ft,

                                      throws java.lang.Exception

the method returns a comma-seperated list of fields, that are affected by a WFSQuery against the subbmitted table. If all fields of the submitted table shall be selected to method just returns "*".

example:

"table1.ID,table1.NAME,table1.VALUE"

Throws:

java.lang.Exception

getTableName

private java.lang.String getTableName(FeatureType ft,
                                      java.lang.String prop)

extracts the table name from a property. it is assumed that the property name is constructed like this: table.propertyname or schema.table.propertyname. if no table is specified with a property name, the name of the feature types master table will be returned.

createResponse

protected OGCWebServiceResponse[] createResponse(java.util.HashMap map,
                                                 java.lang.String[] affectedFeatureTypes)
                                          throws java.lang.Exception

create a response object from the GMLFeatureCollections store into the submitted HashMap

Throws:

java.lang.Exception
