Imports
org.hibernate.QueryException, org.hibernate.dialect.function.CastFunction, .SQLFunction, org.hibernate.hql.internal.ast.util.ColumnHelper, org.hibernate.type.Type, antlr.SemanticException
Represents a cast function call. We handle this specially because its type argument has a semantic meaning to the HQL query (its not just pass through).
