Class BoundedInputStream

  • All Implemented Interfaces:
    Closeable, AutoCloseable

    public class BoundedInputStream
    extends InputStream
    Very slight modification of Commons' BoundedInputStream so that we can figure out if this hit the bound or not.

    This relies on IOUtils' skip and read to try to fully read/skip inputstream.

    • Constructor Detail

      • BoundedInputStream

        public BoundedInputStream​(long max,
                                  InputStream in)
    • Method Detail

      • read

        public int read​(byte[] b)
                 throws IOException
        Invokes the delegate's read(byte[]) method.
        Overrides:
        read in class InputStream
        Parameters:
        b - the buffer to read the bytes into
        Returns:
        the number of bytes read or -1 if the end of stream or the limit has been reached.
        Throws:
        IOException - if an I/O error occurs
      • read

        public int read​(byte[] b,
                        int off,
                        int len)
                 throws IOException
        Invokes the delegate's read(byte[], int, int) method.

        This does not have the same guarantees as IOUtil's readFully()...be careful.

        Overrides:
        read in class InputStream
        Parameters:
        b - the buffer to read the bytes into
        off - The start offset
        len - The number of bytes to read
        Returns:
        the number of bytes read or -1 if the end of stream or the limit has been reached.
        Throws:
        IOException - if an I/O error occurs
      • skip

        public long skip​(long n)
                  throws IOException
        Invokes the delegate's skip(long) method. As with InputStream generally, this does not guarantee reading n bytes. Use IOUtils' skipFully for that functionality.
        Overrides:
        skip in class InputStream
        Parameters:
        n - the number of bytes to skip
        Returns:
        the actual number of bytes skipped
        Throws:
        IOException - if an I/O error occurs
      • mark

        public void mark​(int readLimit)
        Overrides:
        mark in class InputStream
      • hasHitBound

        public boolean hasHitBound()
