                ScaleHint scaleHint,
                WFSQuery query)

Creates a new DataSource_Impl object.

Parameters:

name - name of the featuretype to access

type - type of the data source (LOCALWFS, REMOTEWFS)

ows - OGCWebService instance for accessing the data source

scaleHint -

query - filter condition

DataSource_Impl

DataSource_Impl(java.lang.String name,
                java.lang.String geometryProperty,
                OGCWebService ows,
