Package com.pd4ml.pdf.cos.path

COS paths: a compact syntax for addressing an object in a PDF document, like /Root/Pages/Kids[0], and its evaluator.

Class Summary

Class	Description
COSPath	A parsed COS path: a starting point (the document trailer, or an explicit indirect object) plus a list of navigation steps.
COSPathEvaluator	Resolves a COSPath against a COSDocument (or an arbitrary starting COSBase node), auto-dereferencing indirect references at every step so callers never see a bare COSObject.
COSPathParser	Parses the textual COS path syntax documented on COSPath into a COSPath instance.
COSPathSegment	One navigation step of a COSPath: descend into a dictionary by key, into an array by index, or jump directly to an arbitrary indirect object.

Enum Summary

Enum	Description
COSPath.RootKind	Where a path's navigation starts.
COSPathSegment.Kind	The three kinds of step a COS path can take.

Exception Summary

Exception	Description
COSPathException	Raised for a malformed COS path expression, or (only from the *Strict evaluator methods) when a path cannot be resolved against a particular document -- an intermediate step lands on a node of the wrong kind, a dictionary key is missing, or an array index is out of range.
