Description copied from interface: SpatialDialect

Returns the SQL fragment for the SQL WHERE-clause when parsing org.hibernatespatial.criterion.SpatialRelateExpressions into prepared statements.

Specified by:

getSpatialRelateSQL in interface SpatialDialect

Parameters:

columnName - The name of the geometry-typed column to which the relation is applied

spatialRelation - The type of spatial relation (as defined in SpatialRelation).

Returns:

SQL fragment SpatialRelateExpression

delegateContributeTypes

default void delegateContributeTypes(org.hibernate.boot.model.TypeContributions typeContributions,
                                     org.hibernate.service.ServiceRegistry serviceRegistry)

Specified by:

getSpatialFilterExpression in interface SpatialDialect

Parameters:

columnName - The name of the geometry-typed column to which the filter is be applied

Returns:

Rhe SQL fragment for the SpatialFilterExpression

default String getSpatialAggregateSQL(String columnName,
                                      int aggregation)

Description copied from interface: SpatialDialect

Returns the SQL fragment for the specfied Spatial aggregate expression.

Specified by:

getSpatialAggregateSQL in interface SpatialDialect

Parameters:

columnName - The name of the Geometry property

aggregation - The type of SpatialAggregate

Returns:

The SQL fragment for the projection

getDWithinSQL

default String getDWithinSQL(String columnName)

Description copied from interface: SpatialDialect

Returns The SQL fragment when parsing a DWithinExpression.

Specified by:

getDWithinSQL in interface SpatialDialect

Parameters:

columnName - The geometry column to test against

Returns:

The SQL fragment when parsing a DWithinExpression.

getHavingSridSQL

default String getHavingSridSQL(String columnName)

Description copied from interface: SpatialDialect

Returns the SQL fragment when parsing a HavingSridExpression.

Specified by:

getHavingSridSQL in interface SpatialDialect

Parameters:

supportsFiltering

default boolean supportsFiltering()

Description copied from interface: SpatialDialect

Returns true if this SpatialDialect supports a specific filtering function.

This is intended to signal DB-support for fast window queries, or MBR-overlap queries.

Specified by:

supportsFiltering in interface SpatialDialect

Returns:

True if filtering is supported

supports

default boolean supports(SpatialFunction function)

Description copied from interface: SpatialDialect

Does this dialect supports the specified SpatialFunction.

Specified by:

supports in interface SpatialDialect

Parameters:

function - SpatialFunction

Returns:

True if this SpatialDialect supports the spatial function specified by the function parameter.
