aggregate - The aggregate function (a value of OracleSpatialAggregate

propertyName - The name of the geometry property

Method Detail

toSqlString

public java.lang.String toSqlString(Criteria criteria,
                                    int position,
                                    CriteriaQuery criteriaQuery)
                             throws HibernateException

Description copied from interface: Projection

Render the SQL fragment to be used in the SELECT clause.

Parameters:

criteria - The local criteria to which this project is attached (for resolution).

position - The number of columns rendered in the SELECT clause before this projection. Generally speaking this is useful to ensure uniqueness of the individual columns aliases.

criteriaQuery - The overall criteria query instance.

Returns:

The SQL fragment to plug into the SELECT

Throws:

HibernateException - Indicates a problem performing the rendering

getTypes

public Type[] getTypes(Criteria criteria,
                       CriteriaQuery criteriaQuery)
                throws HibernateException

Description copied from interface: Projection

Types returned by the rendered SQL fragment. In other words what are the types that would represent the values this projection asked to be pulled into the result set?

Parameters:

criteria - The local criteria to which this project is attached (for resolution).

criteriaQuery - The overall criteria query instance.

Returns:

The return types.

Throws:

HibernateException - Indicates a problem resolving the types
