Constructor Detail

InvDatasetImpl

public InvDatasetImpl(InvDatasetImpl parent,
                      java.lang.String name,
                      FeatureType dataType,
                      java.lang.String serviceName,
                      java.lang.String urlPath)

Constructor from Catalog XML info. You must call finish() before this object is ready to be used. We had to do it this way so that nested service elements could be added through addService(), before we define on the default service.

Parameters:

parent - : parent dataset

name - : display name of dataset

dataType - : DataType name (may be null)

serviceName - : default service (may be null)

urlPath - : URL = server.getURLbase() + urlPath

InvDatasetImpl

public InvDatasetImpl(java.lang.String urlPath,
                      FeatureType dataType,
                      ServiceType stype)

Construct an InvDatasetImpl which refers to a urlPath. This is used to create a standalone InvDatasetImpl, outside of an InvCatalog. An "anonymous" InvServerImpl is created and attached to the InvDataset.

Parameters:

urlPath - : construct URL from this path

dataType - : data type

stype - : ServiceType
