JavaBeans PropertyChangeSupport Template

by Jay Jonas

Property-change events occur whenever the value of a bound property changes for a java bean. You can use a Eclipse template to help you to write all the standard setter code

Open Windows | Preferences. Browse to Java | Editor | Templates. Click on New and enter property_change_support as Name, choose Java Statements as Context and mark Automatically Insert option. Write a meaning description as “property change support for setter method” and copy & paste into Pattern the code as follows:

if (this.${enclosing_method_arguments} == null && ${enclosing_method_arguments} == null) {
return;
}
propertyChangeSupport.firePropertyChange("${enclosing_method_arguments}", this.${enclosing_method_arguments}, ${word_selection})

Take care about that there is no new line at the end of the last line.
Take notes and will never forget it.
