Method: PDF::Reader::ObjectHash#deref_name_or_array

Defined in:
lib/pdf/reader/object_hash.rb

#deref_name_or_array(key) ⇒ Object

If key is a PDF::Reader::Reference object, lookup the corresponding object in the PDF and return it. Otherwise return key untouched.

Guaranteed to only return a PDF Name (symbol), Array or nil. If the dereference results in any other type then a MalformedPDFError exception will raise. Useful when expecting a Name or Array and no other type will do.
