      javax.swing.text.html.MinimalHTMLWriter

public class MinimalHTMLWriter
extends AbstractWriter
extends AbstractWriter

MinimalHTMLWriter is a fallback writer used by the HTMLEditorKit to write out HTML for a document that is a not produced by the EditorKit. The format for the document is:

<html>
   <head>
     <style>
        <!-- list of named styles
         p.normal {
            font-family: SansSerif;
              margin-height: 0;
              font-size: 14
           }
        -->
      </style>
   </head>
   <body>
    <p style=normal>
        <b>Bold, italic, and underline attributes
        of the run are emitted as HTML tags.
        The remaining attributes are emitted as
        part of the style attribute of a <span> tag.
        The syntax is similar to inline styles.</b>
    </p>
   </body>
 </html>

MinimalHTMLWriter

public MinimalHTMLWriter(Writer w,
                         StyledDocument doc,
                         int pos,
                         int len)

Creates a new MinimalHTMLWriter.

Parameters:: w - Writer; doc - StyledDocument; pos - The location in the document to fetch the content.; len - The amount to write out.

Method Detail

write

public void write()
           throws IOException,
                  BadLocationException

Generates HTML output from a StyledDocument.

Specified by:: write in class AbstractWriter

Throws:: IOException - on any I/O error; BadLocationException - if pos represents an invalid location within the document.

writeAttributes

protected void writeAttributes(AttributeSet attr)
                        throws IOException

Writes out all the attributes for the following types: StyleConstants.ParagraphConstants, StyleConstants.CharacterConstants, StyleConstants.FontConstants, StyleConstants.ColorConstants. The attribute name and value are separated by a colon. Each pair is separated by a semicolon.

Overrides:: writeAttributes in class AbstractWriter

Parameters:: attr - an AttributeSet.
Throws:: IOException - on any I/O error

text

protected void text(Element elem)
             throws IOException,
                    BadLocationException

Writes out text.

Overrides:: text in class AbstractWriter

Parameters:: elem - an Element.
Throws:: IOException - on any I/O error; BadLocationException - if pos represents an invalid location within the document.

writeStartTag

protected void writeStartTag(String tag)
                      throws IOException

Writes out a start tag appropriately indented. Also increments the indent level.

Throws:: IOException - on any I/O error

writeEndTag

protected void writeEndTag(String endTag)
                    throws IOException

Writes out an end tag appropriately indented. Also decrements the indent level.

Throws:: IOException - on any I/O error

writeHeader

protected void writeHeader()
                    throws IOException

Writes out the <head> and <style> tags, and then invokes writeStyles() to write out all the named styles as the content of the <style> tag. The content is surrounded by valid HTML comment markers to ensure that the document is viewable in applications/browsers that do not support the tag.

Throws:: IOException - on any I/O error

writeStyles

protected void writeStyles()
                    throws IOException

Writes out all the named styles as the content of the <style> tag.

Throws:: IOException - on any I/O error

writeBody

protected void writeBody()
                  throws IOException,
                         BadLocationException

Iterates over the elements in the document and processes elements based on whether they are branch elements or leaf elements. This method specially handles leaf elements that are text.

Throws:: IOException - on any I/O error; BadLocationException

writeEndParagraph

protected void writeEndParagraph()
                          throws IOException

Emits an end tag for a <p> tag. Before writing out the tag, this method ensures that all other tags that have been opened are appropriately closed off.

Throws:: IOException - on any I/O error

writeStartParagraph

protected void writeStartParagraph(Element elem)
                            throws IOException

Emits the start tag for a paragraph. If the paragraph has a named style associated with it, then this method also generates a class attribute for the <p> tag and sets its value to be the name of the style.

Throws:: IOException - on any I/O error

writeLeaf

protected void writeLeaf(Element elem)
                  throws IOException

Responsible for writing out other non-text leaf elements.

Throws:: IOException - on any I/O error

writeImage

protected void writeImage(Element elem)
                   throws IOException

Responsible for handling Icon Elements; deliberately unimplemented. How to implement this method is an issue of policy. For example, if you're generating an <img> tag, how should you represent the src attribute (the location of the image)? In certain cases it could be a URL, in others it could be read from a stream.

Parameters:: elem - element of type StyleConstants.IconElementName
Throws:: IOException

writeComponent

protected void writeComponent(Element elem)
                       throws IOException

Responsible for handling Component Elements; deliberately unimplemented. How this method is implemented is a matter of policy.

Throws:: IOException

isText

protected boolean isText(Element elem)

Returns true if the element is a text element.

writeContent

protected void writeContent(Element elem,
                            boolean needsIndenting)
                     throws IOException,
                            BadLocationException

Writes out the attribute set in an HTML-compliant manner.

Throws:: IOException - on any I/O error; BadLocationException - if pos represents an invalid location within the document.

writeHTMLTags

protected void writeHTMLTags(AttributeSet attr)
                      throws IOException

Generates bold <b>, italic <i>, and <u> tags for the text based on its attribute settings.

Throws:: IOException - on any I/O error

writeNonHTMLAttributes

protected void writeNonHTMLAttributes(AttributeSet attr)
                               throws IOException

Writes out the remaining character-level attributes (attributes other than bold, italic, and underline) in an HTML-compliant way. Given that attributes such as font family and font size have no direct mapping to HTML tags, a <span> tag is generated and its style attribute is set to contain the list of remaining attributes just like inline styles.

Throws:: IOException - on any I/O error

inFontTag

protected boolean inFontTag()

Returns true if we are currently in a <font> tag.

endFontTag

protected void endFontTag()
                   throws IOException

This is no longer used, instead <span> will be written out.

Writes out an end tag for the <font> tag.

Throws:: IOException - on any I/O error

startFontTag

protected void startFontTag(String style)
                     throws IOException

This is no longer used, instead <span> will be written out.

Writes out a start tag for the <font> tag. Because font tags cannot be nested, this method closes out any enclosing font tag before writing out a new start tag.

Throws:: IOException - on any I/O error

Le contenu de cette page provient du site de Sun, et est généré depuis un cache sur l'infobrol après certains traitements automatisés. La présentation peut donc différer du document original, mais le contenu aussi. Vous pouvez utiliser ce bouton pour afficher la page originale du site de Sun :

Quels sont les motivations de cette démarche?

Maintenir les pages en cache sur différents sites peut offrir plus de disponibilité.

Chaque page est indexée dans la base de donnée, ce qui permet de retrouver facilement les informations, au moyen des sommaires, du moteur de recherche interne, etc.

Des facilités sont mises en place pour que les membres de l'infobrol puissent effectuer des traductions en français des différents documents. Ceci devrait permettre aux débutants en programmation Java de consulter les API en français s'ils maîtrisent moins bien la langue de Shakespeare. Dans le cas où une traduction a été soumise, elle est disponible au moyen d'un lien en bas de page. Si la traduction a été validée, la page s'affiche par défaut en français, et un lien en bas de page permet d'atteindre la version en anglais.

Le code sur l'infobrol est automatiquement coloré selon la syntaxe, et les différents mots clés sont transformés en liens pour accéder rapidement aux informations.

Vous avez la possibilité de partager vos expériences en proposant vos propres extraits de code en utilisant le bouton "ajouter un commentaire" en bas de page. Si vous visitez simplement l'infobrol, vous avez déjà accès à cette fonction, mais si vous étes membre du brol, vous pouvez en plus utiliser des boutons supplémentaires de mise en forme, dont la coloration automatique de vos extraits de codes.
