namespace - may be null (include all feature types from all namespaces)

includeCollections - set to true, if feature collection types shall be included, false otherwise

includeAbstracts - set to true, if abstract types shall be included, false otherwise

Returns:

all feature types, never null

getRootFeatureTypes

public FeatureType[] getRootFeatureTypes()

Description copied from interface: AppSchema

Returns all root feature types that are defined in this application schema.

Specified by:

getRootFeatureTypes in interface AppSchema

Returns:

all root feature types, never null

getFeatureType

public DynamicFeatureType getFeatureType(QName ftName)

Description copied from interface: AppSchema

Retrieves the feature type with the given name.

Specified by:

getFeatureType in interface AppSchema

Parameters:

ftName - feature type name to look up, must not be null

Returns:

the feature type with the given name, or null if no such feature type exists

getDirectSubtypes

public FeatureType[] getDirectSubtypes(FeatureType ft)

Description copied from interface: AppSchema

Retrieves the direct subtypes for the given feature type.

Specified by:

getDirectSubtypes in interface AppSchema

Parameters:
