### Uses of Expression in java.beans

Methods in java.beans that return Expression
`protected Expression` DefaultPersistenceDelegate.`instantiate​(Object oldInstance, Encoder out)` This default implementation of the `instantiate` method returns an expression containing the predefined method name "new" which denotes a call to a constructor with the arguments as specified in the `DefaultPersistenceDelegate`'s constructor.
`protected abstract Expression` PersistenceDelegate.`instantiate​(Object oldInstance, Encoder out)` Returns an expression whose value is `oldInstance`.

Methods in java.beans with parameters of type Expression
`void` Encoder.`writeExpression​(Expression oldExp)` The implementation first checks to see if an expression with this value has already been written.
`void` XMLEncoder.`writeExpression​(Expression oldExp)` Records the Expression so that the Encoder will produce the actual output when the stream is flushed.
