Method Details

createClone

COSBase createClone(COSBase src,
 COSBase dstParent,
 COSDictionary currentPageDict)

Creates a clone of the source.

Parameters:

src - source dictionary or array.

dstParent - for the /P entry; parameter needed because arrays don't keep a parent.

currentPageDict - used to remember whether we have a page parent somewhere or not. Starts with null.

Returns:

a clone, or null if source is null or if there is no clone because it belongs to a different page or to no page.
