Direct Known Subclasses:

PDFPage

public class PDFBuffer
extends PDFOutput

This class is like a StringBuffer, but for creating PDF files instead of strings. It resides entirely in memory so it should be used sparingly. The preferred PDFOutput implementation is PDFOutputStream to prevent large PDF assets from being held in memory.
