public String getTableAlias()

Implements org.hibernate.loader.plan.exec.spi.EntityReferenceAliases.getTableAlias.

Doc from org.hibernate.loader.plan.exec.spi.EntityReferenceAliases.getTableAlias.

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

Returns:String

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