Constructor Detail

EOPropertyNameMapper

public EOPropertyNameMapper(QName[] queryTypeNames,
                            boolean useLegacyPredicates)
                     throws MetadataStoreException

Creates a new EOPropertyNameMapper instance configured for the specified registry objects / aliases.

Parameters:

queryTypeNames - queried type names, must not be null

useLegacyPredicates - if true, legacy-style PostGIS spatial predicates are used (e.g. Intersects instead of ST_Intersects)

Throws:

MetadataStoreException - if any of the queried type names is not known / supported

Method Detail

getQueryTypes

public Collection<AliasedRIMType> getQueryTypes()

Returns the queried types (including aliases).

Returns:

queried types, never null

getReturnType

public AliasedRIMType getReturnType(QName[] returnTypeNames)
                             throws MetadataStoreException

Determines the query type to be returned.

Parameters:

returnTypeNames - return type names as specified in the query

Returns:

query type to be returned, never null

Throws:

MetadataStoreException - if the specified return type names do not correspond to the query types

getTable

public SlotMapper.Table getTable(AliasedRIMType queryType)

getTableAlias

public String getTableAlias(AliasedRIMType queryType)

getAdditionalJoins

public List<Join> getAdditionalJoins()

getMapping

public PropertyNameMapping getMapping(ValueReference propName,
                                      TableAliasManager aliasManager)
                               throws FilterEvaluationException,
                                      UnmappableException

Description copied from interface: PropertyNameMapper

Returns the PropertyNameMapping for the given ValueReference.

Specified by:

getMapping in interface PropertyNameMapper

Parameters:

propName - property name, can be null (indicates that the default geometry property of the root object is requested)

aliasManager - manager for creating and tracking table aliases, never null

Returns:

relational mapping, may be null (if no mapping is possible)

Throws:

FilterEvaluationException - indicates that the ValueReference is invalid

UnmappableException
