    • Method Detail

      • clear

        public int clear()
        Clear the buffer

      • shrink

        public int shrink()
        Shrink the buffer. This will reclaim currently unused space in the buffer, reducing memory but potentially increasing the cost of resizing the buffer

      • unread

        public void unread​(byte[] b,
                   int off,
                   int len)
            throws java.io.IOException
        Overrides:
        unread in class java.io.PushbackInputStream
        Throws:
        java.io.IOException

      • unread

        public void unread​(int b)
            throws java.io.IOException
        Overrides:
        unread in class java.io.PushbackInputStream
        Throws:
        java.io.IOException

      • read

        public int read()
         throws java.io.IOException

      • read

        public int read​(byte[] b,
                int off,
                int len)
         throws java.io.IOException
        Overrides:
        read in class java.io.PushbackInputStream
        Throws:
        java.io.IOException

      • skip

        public long skip​(long n)
          throws java.io.IOException
        Overrides:
