      default DefaultFeatureType editFeatureType(TableReference table, FeatureTypeBuilder feature) throws DataStoreException
      Invoked after analysis of a table for allowing modifications of the inferred feature type. The given builder is initialized with all properties inferred from the table definition. Implementation of this method can add properties (e.g. operations) but should not remove or rename properties. It is okay to add or remove characteristics on properties.

      The default implementation returns feature.build() without making any change.

      Parameters:
      table - the catalog (if present), schema (if present) and table name.
      feature - a feature type builder initialized with all properties inferred by the analysis of a table. This builder can be modified in-place.
      Returns:
      the feature type to use for the specified table.
      Throws:
      DataStoreException - if an error occurred while modifying the feature type.

    • isCyclicAssociationAllowed

      default boolean isCyclicAssociationAllowed(TableReference dependency)
      Returns true if the given dependency is allowed to have an association to its dependent feature. A value of true creates a cyclic dependency, which SQLStore can manage but may surprise users. The default value is false.
      Parameters:
      dependency - the dependency table.
      Returns:
      whether the dependency is allowed to have an association to its parent.
