        public static boolean shouldEncodeNestedFilters()

      • buildMappings

        public static Set<FeatureTypeMapping> buildMappings​(AppSchemaDataAccessDTO config)
                                                     throws IOException
        Takes a config object and creates a set of mappings.

        In the process will parse xml schemas to geotools' Feature Model types and descriptors, connect to source datastores and build the mapping objects from source FeatureTypes to the target ones.

        Returns:
        a Set of FeatureTypeMapping source to target FeatureType mapping definitions
        Throws:
        IOException - if any error occurs while creating the mappings

        public static Set<FeatureTypeMapping> buildMappings​(AppSchemaDataAccessDTO config,
                                                            DataAccessMap sourceDataStoreMap)
                                                     throws IOException
        This method will not create a source data store if an equivalent one (i.e. same configuration parameters) is found in the provided sourceDataStoreMap.
        Parameters:
        sourceDataStoreMap - map holding the source data stores created so far, e.g. while parsing App-Schema configuration files included by the one currently being processed
        Throws:
        IOException

        public static Expression parseOgcCqlExpression​(String sourceExpr,
                                                       FilterFactory ff)
                                                throws DataSourceException
        Utility method that parses an CQL expression from its text representation. If the provided expression test representation is NULL, Expression.NIL is returned.
        Parameters:
        sourceExpr - the expression in its text representation
        ff - filter factory used to build the final expression
        Returns:
        the parsed expression
        Throws:
        DataSourceException - if the expression text representation could not be parsed
