Method Details

isJoining

public static boolean isJoining()

Convenience method for "joining" property.

isJoiningSet

public static boolean isJoiningSet()

isOrUnionReplacementEnabled

public static boolean isOrUnionReplacementEnabled()

shouldEncodeNestedFilters

public static boolean shouldEncodeNestedFilters()

Convenience method to check whether native encoding of nested filters is enabled.

Returns:

true if native encoding of nested filters is enabled, false otherwise

buildMappings

public static Set<FeatureTypeMapping> buildMappings(AppSchemaDataAccessDTO config,
 boolean isInclude)
                                             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

buildMappings

public static Set<FeatureTypeMapping> buildMappings(AppSchemaDataAccessDTO config)
                                             throws IOException

Takes a config object and creates a set of mappings, assumes the mappings are not from includes

Parameters:

config - the configuration object

Returns:

a Set of FeatureTypeMapping source to target

Throws:

IOException - if any error occurs while creating the mappings

buildMappings

public static Set<FeatureTypeMapping> buildMappings(AppSchemaDataAccessDTO config,
 DataAccessMap sourceDataStoreMap,
 boolean isInclude)
                                             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

isInclude - whether the mappings are for an include

Throws:

IOException

• buildMappings(AppSchemaDataAccessDTO)

parseOgcCqlExpression

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
