• registerTag

  protected void registerTag(HTML.Tag t,
                             HTMLDocument.HTMLReader.TagAction a)

  Registers a handler for the given tag. By default all of the well-known tags will have been registered. This can be used to change the handling of a particular tag or to add support for custom tags.

• pushCharacterStyle

  protected void pushCharacterStyle()

  Pushes the current character style on a stack in preparation for forming a new nested character style.

• popCharacterStyle

  protected void popCharacterStyle()

  Pops a previously pushed character style off the stack to return to a previous style.

• textAreaContent

  protected void textAreaContent(char[] data)

  Adds the given content to the textarea document. This method gets called when we are in a textarea context. Therefore all text that is seen belongs to the text area and is hence added to the TextAreaDocument associated with the text area.

• preContent

  protected void preContent(char[] data)

  Adds the given content that was encountered in a PRE element. This synthesizes lines to hold the runs of text, and makes calls to addContent to actually add the text.

• blockOpen

  protected void blockOpen(HTML.Tag t,
                           MutableAttributeSet attr)

  Adds an instruction to the parse buffer to create a block element with the given attributes.

• blockClose

  protected void blockClose(HTML.Tag t)

  Adds an instruction to the parse buffer to close out a block element of the given type.

• addContent

  protected void addContent(char[] data,
                            int offs,
                            int length)

  Adds some text with the current character attributes.

  Parameters:

  data - the content to add

  offs - the initial offset

• addContent

  protected void addContent(char[] data,
                            int offs,
                            int length,
                            boolean generateImpliedPIfNecessary)

  Adds some text with the current character attributes.

  Parameters:

  data - the content to add

  offs - the initial offset

  length - the length

  generateImpliedPIfNecessary - whether to generate implied paragraphs
