Method Detail

getTableAlias

public String getTableAlias()

Description copied from interface: EntityReferenceAliases

Obtain the table alias used for referencing the table of the EntityReference.

Note that this currently just returns the "root alias" whereas sometimes an entity reference covers multiple tables. todo : to help manage this, consider a solution like TableAliasRoot from the initial ANTLR re-work see http://anonsvn.jboss.org/repos/hibernate/core/branches/antlr3/src/main/java/org/hibernate/sql/ast/alias/TableAliasGenerator.java

Specified by:

getTableAlias in interface EntityReferenceAliases

Returns:

The (root) table alias for the described entity reference.

getColumnAliases

public EntityAliases getColumnAliases()

Description copied from interface: EntityReferenceAliases

Obtain the column aliases for the select fragment columns associated with the described entity reference. These are the column renames by which the values can be extracted from the SQL result set.

Specified by:

getColumnAliases in interface EntityReferenceAliases

Returns:

The column aliases associated with the described entity reference.
