Method Summary

Modifier and Type	Method and Description
void	contributeTypes(TypeContributions typeContributions, ServiceRegistry serviceRegistry) Allows the Dialect to contribute additional types
boolean	equivalentTypes(int typeCode1, int typeCode2) Do the given JDBC type codes, as defined in Types represent essentially the same type in this dialect of SQL? The default implementation treats NUMERIC and DECIMAL as the same type, and FLOAT, REAL, and DOUBLE as essentially the same type, since the ANSI SQL specification fails to meaningfully distinguish them.
String	getDWithinSQL(String columnName) Returns The SQL fragment when parsing a DWithinExpression.
String	getHavingSridSQL(String columnName) Returns the SQL fragment when parsing a HavingSridExpression.
String	getIsEmptySQL(String columnName, boolean isEmpty) Returns the SQL fragment when parsing a IsEmptyExpression or IsNotEmpty expression.
String	getSpatialAggregateSQL(String columnName, int aggregation) Returns the SQL fragment for the specfied Spatial aggregate expression.
String	getSpatialFilterExpression(String columnName) Returns the SQL fragment for the SQL WHERE-expression when parsing org.hibernate.spatial.criterion.SpatialFilterExpressions into prepared statements.
String	getSpatialRelateSQL(String columnName, int spatialRelation) Returns the SQL fragment for the SQL WHERE-clause when parsing org.hibernatespatial.criterion.SpatialRelateExpressions into prepared statements.
boolean	supports(SpatialFunction function) Does this dialect supports the specified SpatialFunction.
boolean	supportsFiltering() Returns true if this SpatialDialect supports a specific filtering function.

Method Detail

contributeTypes

public void contributeTypes(TypeContributions typeContributions,
                            ServiceRegistry serviceRegistry)

Description copied from class: Dialect

Allows the Dialect to contribute additional types

Overrides:

contributeTypes in class PostgreSQL82Dialect

Parameters:

typeContributions - Callback to contribute the types

serviceRegistry - The service registry

equivalentTypes

public boolean equivalentTypes(int typeCode1,

Description copied from class: Dialect

Do the given JDBC type codes, as defined in Types represent essentially the same type in this dialect of SQL?
