Java Source Code / Java Documentation » PDF » PDFBox 0.7.3 » org.pdfbox.io   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.io.PushbackInputStream    org.pdfbox.io.PushBackInputStream All known Subclasses:   org.pdfbox.io.ByteArrayPushBackInputStream, PushBackInputStream public class PushBackInputStream extends java.io.PushbackInputStream (Code) A simple subclass that adds a few convience methods. author:    Ben Litchfield version:    $Revision: 1.6 $ Constructor Summary public   PushBackInputStream(InputStream input, int size)      Constructor. Parameters:   input - The input stream. Parameters:   size - The size of the push back buffer. throws:   IOException - If there is an error with the stream. Method Summary public  void fillBuffer()      This is a method used to fix PDFBox issue 974661, the PDF parsing code needs to know if there is at least x amount of data left in the stream, but the available() method returns how much data will be available without blocking. public  boolean isEOF()      A simple test to see if we are at the end of the stream. public  int peek()      This will peek at the next byte. Constructor Detail PushBackInputStream public PushBackInputStream(InputStream input, int size) throws IOException(Code) Constructor. Parameters:   input - The input stream. Parameters:   size - The size of the push back buffer. throws:   IOException - If there is an error with the stream. Method Detail fillBuffer public void fillBuffer() throws IOException(Code) This is a method used to fix PDFBox issue 974661, the PDF parsing code needs to know if there is at least x amount of data left in the stream, but the available() method returns how much data will be available without blocking. PDFBox is willing to block to read the data, so we will first fill the internal buffer. throws:   IOException - If there is an error filling the buffer. isEOF public boolean isEOF() throws IOException(Code) A simple test to see if we are at the end of the stream. true if we are at the end of the stream. throws:   IOException - If there is an error reading the next byte. peek public int peek() throws IOException(Code) This will peek at the next byte. The next byte on the stream, leaving it as available to read. throws:   IOException - If there is an error reading the next byte.
