public class DefaultEditorKit
extends EditorKit

This is the set of things needed by a text component to be a reasonably functioning editor for some type of text document. This implementation provides a default implementation which treats text as plain text and provides a minimal set of actions for a simple editor.

Newlines
  There are two properties which deal with newlines. The system property, `line.separator`, is defined to be platform-dependent, either "\n", "\r", or "\r\n". There is also a property defined in `DefaultEditorKit`, called `EndOfLineStringProperty`, which is defined automatically when a document is loaded, to be the first occurrence of any of the newline characters. When a document is loaded, `EndOfLineStringProperty` is set appropriately, and when the document is written back out, the `EndOfLineStringProperty` is used. But while the document is in memory, the "\n" character is used to define a newline, regardless of how the newline is defined when the document is on disk. Therefore, for searching purposes, "\n" should always be used. When a new document is created, and the `EndOfLineStringProperty` has not been defined, it will use the System property when writing out the document.

  Note that `EndOfLineStringProperty` is set on the `Document` using the `get/setProperty` methods. Subclasses may override this behavior.
