  • Method Details

    • toByteArray

      public static byte[] toByteArray(InputStream in) throws IOException
      Reads the input stream and returns its contents as a byte array.
      Parameters:
      in - the input stream to read from.
      Returns:
      the byte array
      Throws:
      IOException - if an I/O error occurs
    • copy

      public static long copy(InputStream input, OutputStream output) throws IOException
      Copies all the contents from the given input stream to the given output stream.
      Parameters:
      input - the input stream
      output - the output stream
      Returns:
      the number of bytes that have been copied
      Throws:
      IOException - if an I/O error occurs
    • populateBuffer

      public static long populateBuffer(InputStream in, byte[] buffer) throws IOException
      Populates the given buffer with data read from the input stream. If the data doesn't fit the buffer, only the data that fits in the buffer is read. If the data is less than fits in the buffer, the buffer is not completely filled.
      Parameters:
      in - the input stream to read from
      buffer - the buffer to fill
      Returns:
      the number of bytes written to the buffer
      Throws:
      IOException - if an I/O error occurs
    • closeQuietly

      public static void closeQuietly(InputStream input)
      Unconditionally close an InputStream.

      Equivalent to InputStream.close(), except any exceptions will be ignored. This is typically used in finally blocks.

      Parameters:
      input - the InputStream to close, may be null or already closed
    • closeQuietly

      public static void closeQuietly(Reader input)
      Unconditionally close an Reader.

      Equivalent to Reader.close(), except any exceptions will be ignored. This is typically used in finally blocks.

      Parameters:
      input - the Reader to close, may be null or already closed
    • closeQuietly

      public static void closeQuietly(Writer output)
      Unconditionally close a Writer.

      Equivalent to Writer.close(), except any exceptions will be ignored. This is typically used in finally blocks.

      Parameters:
      output - the Writer to close, may be null or already closed
    • closeQuietly

      public static void closeQuietly(OutputStream output)
      Unconditionally close an OutputStream.

      Equivalent to OutputStream.close(), except any exceptions will be ignored. This is typically used in finally blocks.

      Parameters:
      output - the OutputStream to close, may be null or already closed
