Class DefaultEditorKit
- java.lang.Object
-
- javax.swing.text.EditorKit
-
- javax.swing.text.DefaultEditorKit
- All Implemented Interfaces:
- Serializable, Cloneable
- Direct Known Subclasses:
- StyledEditorKit
public class DefaultEditorKit extends EditorKit
- 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 inDefaultEditorKit
, calledEndOfLineStringProperty
, 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, theEndOfLineStringProperty
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 theEndOfLineStringProperty
has not been defined, it will use the System property when writing out the document.Note that
EndOfLineStringProperty
is set on theDocument
using theget/putProperty
methods. Subclasses may override this behavior.
