public class UpdateStatementStateObject extends AbstractModifyStatementStateObject
UPDATE clause of a query consists of a conditional expression used to
select objects or values that satisfy the expression. The UPDATE clause
restricts the result of a select statement or the scope of an update operation.

buildModifyClause()
Creates the actual
AbstractModifyClauseStateObject that represents the modify clause. |

getExpression()
Returns the actual parsed object if this
StateObject representation of the JPQL query
was created by parsing an existing JPQL query. |
UpdateClauseStateObject |
getModifyClause()
Returns the state object representing the
UPDATE clause. |
void |
setExpression(UpdateStatement expression)
Keeps a reference of the
parsed object object, which should only be
done when this object is instantiated during the conversion of a parsed JPQL query into
StateObjects. |
