com.itextpdf.text.pdf.PdfDictionary
PdfDictionary is the Pdf dictionary object.
A dictionary is an associative table containing pairs of objects. The first element of each pair is called the key and the second element is called the value. Unlike dictionaries in the PostScript language, a key must be a PdfName. A value can be any kind of PdfObject, including a dictionary. A dictionary is generally used to collect and tie together the attributes of a complex object, with each key-value pair specifying the name and value of an attribute.
A dictionary is represented by two left angle brackets (<<), followed by a sequence of key-value pairs, followed by two right angle brackets (>>).
This object is described in the 'Portable Document Format Reference Manual version 1.7' section 3.2.6 (page 59-60).
