Class EmptyStringToNullEditor

java.lang.Object

com.github.stefanbirkner.editors.EmptyStringToNullEditor

All Implemented Interfaces:

PropertyEditor

Direct Known Subclasses:

SfbEnumEditor

public class EmptyStringToNullEditor
extends Object
implements PropertyEditor

An EmptyStringToNullEditor is a wrapper for building PropertyEditors that handle setAsText("") like setAsText(null).

Wrap the original editor with the EmptyStringToNullEditor

PropertyEditor wrappedEditor = new EmptyStringToNullEditor(originalEditor);

When somebody calls setAsText("") on the wrappedEditor, then it calls setAsText(null) on the originalEditor. All other values and all other methods are delegated to the originalEditor.
