## multivalent.std.adaptor
Class HexDump

    java.lang.Object
      multivalent.VObject
          multivalent.Behavior
              multivalent.MediaAdaptor
                  multivalent.std.adaptor.HexDump

public class HexDump
extends MediaAdaptor

Like `od` and `strings`, simple hex/ASCII dump catch all for general binary data that the user nevertheless wants to view.

LATER: different data formats like od

Method Detail

### parse

    public java.lang.Object parse(INode parent)
                           throws java.lang.Exception

  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`
  See Also:
    `for a convenient way to attach spans`

### toHTML

    public java.lang.String toHTML()

### semanticEventAfter

    public boolean semanticEventAfter(SemanticEvent se,
                                      java.lang.String msg)

  Choose among hex only, ASCII only, and mixed displays.

  Overrides:
    `semanticEventAfter` in class `MediaAdaptor`
