Constructor Detail

FragmentListBox

public FragmentListBox(RandomAccessFile raf,
                       BoxHolder parent)

Constructor with superbox.

Parameters:

parent - parent superbox of this box. The parent may be a FragmentTableBox or a CrossReferenceBox.

Method Detail

readBox

public boolean readBox()
                throws IOException

Reads the box, putting appropriate information in the RepInfo object. setModule, setBoxHeader, setRepInfo and setDataInputStream must be called before readBox is called. readBox must completely consume the box, so that the next byte to be read by the DataInputStream is the FF byte of the next Box.

Specified by:

readBox in class JP2Box

Throws:

IOException

getFragmentList

protected List getFragmentList()

Returns the fragment list. If there are external references to fragments, returns null; in this case, a warning message has been added to the RepInfo object.

getSelfPropName

protected String getSelfPropName()

Returns the name of the Box.

Overrides:
