@FunctionalInterface
public interface ITableListener

A listener that listens to changes in values in a ITable

Method Summary

Modifier and Type	Method and Description
void	valueChanged(ITable source, java.lang.String key, java.lang.Object value, boolean isNew) Called when a key-value pair is changed in a ITable
default void	valueChangedEx(ITable source, java.lang.String key, java.lang.Object value, int flags) Extended version of valueChanged.

Method Detail

valueChanged

void valueChanged(ITable source,
                  java.lang.String key,
                  java.lang.Object value,
                  boolean isNew)

Called when a key-value pair is changed in a ITable

Parameters:

source - the table the key-value pair exists in

key - the key associated with the value that changed

value - the new value

isNew - true if the key did not previously exist in the table, otherwise it is false

valueChangedEx

default void valueChangedEx(ITable source,
                            java.lang.String key,
                            java.lang.Object value,
                            int flags)

Extended version of valueChanged. Called when a key-value pair is changed in a ITable. The default implementation simply calls valueChanged(). If this is overridden, valueChanged() will not be called.

Parameters:

source - the table the key-value pair exists in

key - the key associated with the value that changed

value - the new value

flags - update flags; for example, NOTIFY_NEW if the key did not previously exist in the table
