Package org.hibernate.spatial.dialect.mysql

Class MySQL56SpatialDialect

  • All Implemented Interfaces:
    java.io.Serializable, org.hibernate.exception.spi.ConversionContext, SpatialDialect
    Direct Known Subclasses:
    MySQL56InnoDBSpatialDialect
    public class MySQL56SpatialDialect
extends org.hibernate.dialect.MySQL55Dialect
implements SpatialDialect
    Extends the MySQL5Dialect by including support for the spatial operators.

    This SpatialDialect uses the ST_* spatial operators that operate on exact geometries which have been added in MySQL version 5.6.1. Previous versions of MySQL only supported operators that operated on Minimum Bounding Rectangles (MBR's). This dialect my therefore produce different results than the other MySQL spatial dialects.
