getValueChange | GetValueChange | undefined | A function that returns information about any |
returns | void | This has no return value. |
A ValuesListener
is provided when using the addValuesListener
method. See that method for specific examples.
When called, a ValuesListener
is given a reference to the Store
and a GetValueChange
function that can be used to query Values
before and after the current transaction.
Note that if the listener was manually forced to be called (with the callListener
method rather than due to a real change in the Store
), the GetValueChange
function will not be present.
