getDiscriminatorAlias

java.lang.String getDiscriminatorAlias(java.lang.String suffix)

Get the result set aliases used for the identifier columns, given a suffix

getDiscriminatorColumnName

java.lang.String getDiscriminatorColumnName()

Returns:

the column name for the discriminator as specified in the mapping.

hasRowId

boolean hasRowId()

Does the result set contain rowids?

hydrate

java.lang.Object[] hydrate(java.sql.ResultSet rs,
                           java.io.Serializable id,
                           java.lang.Object object,
                           Loadable rootLoadable,
                           java.lang.String[][] suffixedPropertyColumns,
                           boolean allProperties,

                    throws java.sql.SQLException,
                           HibernateException

Retrieve property values from one row of a result set

Throws:

java.sql.SQLException

HibernateException

isAbstract

boolean isAbstract()

registerAffectingFetchProfile

void registerAffectingFetchProfile(java.lang.String fetchProfileName)

Register the name of a fetch profile determined to have an affect on the underlying loadable in regards to the fact that the underlying load SQL needs to be adjust when the given fetch profile is enabled.

Parameters:

fetchProfileName - The name of the profile affecting this.

getTableAliasForColumn

java.lang.String getTableAliasForColumn(java.lang.String columnName,
                                        java.lang.String rootAlias)

Given a column name and the root table alias in use for the entity hierarchy, determine the proper table alias for the table in that hierarchy that contains said column.

NOTE : Generally speaking the column is not validated to exist. Most implementations simply return the root alias; the exception is JoinedSubclassEntityPersister

Parameters:

columnName - The column name

rootAlias - The hierarchy root alias

Returns:

The proper table alias for qualifying the given column.
