The DefaultStyledDocument class is the implementation of the StyledDocument interface
provided with the Swing components. It serves as the data model for the JTextPane component.

Creating a DefaultStyledDocument
You can create a DefaultStyledDocument in any one of the three ways listed here:

public DefaultStyledDocument()
DefaultStyledDocument document = new DefaultStyledDocument();

public DefaultStyledDocument(StyleContext styles)
StyleContext context = new StyleContext();
DefaultStyledDocument document = new DefaultStyledDocument(context);

public DefaultStyledDocument(AbstractDocument.Content content, StyleContext styles)
AbstractDocument.Content content = new StringContent();
DefaultStyledDocument document = new DefaultStyledDocument(content, context);

You can share the StyleContext between multiple documents or use the default context.
In addition, you can predefine the content using one of the AbstractDocument.Content imple-
mentations, either GapContent or StringContent . It is the responsibility of one of these Content
implementations to store the actual Document content.

DefaultStyledDocument Properties
Besides having a default root element to describe the contents of the document, the
DefaultStyledDocument makes available the style names as an Enumeration . These are the only
two properties defined at the DefaultStyledDocument level, as shown in Table 16-2. There are
other properties you can get for a DefaultStyledDocument ; however, they require the position
or AttributeSet from which to get them.
