public void buildBefore(Document doc)
MediaAdaptor
MediaAdaptor.parse(INode)
concrete document format and put into tree.
Subclasses should set their style sheets, then parse document body, so can progressively render page, if applicable.
buildBefore
in class MediaAdaptor
Mark
public java.lang.Object parse(INode parent) throws java.lang.Exception
MediaAdaptor
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.
parse

Image
.
However, the primary job of a media adaptor is to add content to the document tree.
java.lang.Exception
