Package com.pd4ml.pdf.cos

The PDF object model (COS): arrays, dictionaries, names, numbers, strings, streams and indirect references, and COSDocument, the whole document. The PDF tools are built on it.

Interface Summary

Interface	Description
COSObjectable	Implemented by higher level, typed wrappers around a raw COS node (analogous to PDModel-style classes layered on top of PDFBox's COS layer).
ICOSVisitor<T>	Visitor over the COS object graph, e.g.

Class Summary

Class	Description
COSArray	A PDF array object.
COSBase	Base class for every object that can appear in the COS (Carousel Object Structure) layer of a PDF document: booleans, numbers, strings, names, arrays, dictionaries, streams, the null object and indirect references.
COSBoolean	A PDF boolean object: true or false.
COSDictionary	A PDF dictionary object: an unordered (here: insertion-ordered, for deterministic output) map from COSName keys to arbitrary COS values.
COSDocument	The in-memory representation of a whole PDF file's COS layer: the table of indirect objects keyed by COSObjectKey, and the trailer dictionary that names the document's root ("Catalog") and other special objects.
COSFloat	A PDF real number object, e.g.
COSInteger	A PDF integer object.
COSName	A PDF name object, e.g.
COSNull	The PDF null object.
COSNumber	Base class for the two PDF numeric object types, integers and reals.
COSObject	An indirect reference, i.e.
COSObjectKey	The identity of an indirect PDF object: its object number and generation number, e.g.
COSStream	A PDF stream object: a COSDictionary (the "stream dictionary") together with a run of raw bytes.
COSString	A PDF string object.
Main	Command-line demonstration of the COS API: parses a PDF file (path given as the first argument), prints a short structural summary, then evaluates every COS path expression given as subsequent arguments.

Exception Summary

Exception	Description
COSException	Base checked exception for all errors originating from the COS object model, the low level PDF parser, or the COS path engine.
