Examples of BufferedValueModel

DisplayProject.binding.value.BufferedValueModel
A ValueModel that wraps another ValueModel, the subject, and delays changes of the subject's value. Returns the subject's value until a value has been set. The buffered value is not written to the subject until the trigger channel changes to Boolean.TRUE. The buffered value can be flushed by changing the trigger channel value to Boolean.FALSE. Note that the commit and flush events are performed only if the trigger channel fires a change event. Since a plain ValueHolder fires no property change event if a value is set that has been set before, it is recommended to use a {@link Trigger} insteadand invoke its #triggerCommit and triggerFlush methods.
The BufferedValueModel has been designed to behave much like its subject when accessing the value. Therefore it throws all exceptions that would arise when accessing the subject directly. Hence, attempts to read or write a value while the subject is null are always rejected with a NullPointerException.
This class provides the bound read-write properties subject and triggerChannel for the subject and trigger channel and a bound read-only property buffering for the buffering state.
The BufferedValueModel registers listeners with the subject and trigger channel. It is recommended to remove these listeners by invoking #release if the subject and trigger channel live much longer than this buffer. After #release has been called you must not use the BufferedValueModel instance any longer. As an alternative you may use event listener lists in subjects and trigger channels that are based on WeakReferences.
If the subject value changes while this model is in buffering state this change won't show through as this model's new value. If you want to update the value whenever the subject value changes, register a listener with the subject value and flush this model's trigger.
