com.itextpdf.text.pdf.PdfArray
PdfArray is the PDF Array object.
An array is a sequence of PDF objects. An array may contain a mixture of object types. An array is written as a left square bracket ([), followed by a sequence of objects, followed by a right square bracket (]).
This object is described in the 'Portable Document Format Reference Manual version 1.7' section 3.2.5 (page 58). @see PdfObject
