Description copied from class: MediaAdaptor

Parses a document's data format and constructs a document tree. Structure is represented in internal nodes and content (text, images, video, ...) at the leaves.

Before using, invoke MediaAdaptor.setInput(InputUni). The newly constructed document tree should attach to parent. The parent is usually but not necessarily a Document. Paginated documents should build the current page only, as indicated by the attribute Document.ATTR_PAGE, and report their page count to Document.ATTR_PAGECOUNT. Metadata, such as author and dates, should be stored in the closed containing Document.

If encountering an unfixable/unrecoverable parsing error, usually due to an invalid data format, throws a ParseException. (This does not supercede IOException.) When media adaptor is done or has thrown an exception, the client must MediaAdaptor.close() it.

Subclasses should not rely on being able to obtain a Root, Browser, or Multivalent; in such cases it is acceptable to reduce functionality.

Specified by:

parse in class MediaAdaptor

Returns:

whatever Object is appropriate to the media adaptor. For HTML it is the root of the HTML tree (which has name "html"), for documents with no single root it can be parent, for an image constuctor it could be an Image. However, the primary job of a media adaptor is to add content to the document tree.

Throws:

java.lang.Exception

toHTML

public java.lang.String toHTML()
                        throws java.io.IOException

Throws:

java.io.IOException

type2String

public void type2String(java.lang.String type,
                        java.lang.StringBuffer sb)

Inserts links to classes.
