      • cleanup

        public static void cleanup​(java.io.Closeable... closeables)
        Closes the Closeable objects and ignore any IOException or null pointers. Must only be used for cleanup in exception handlers.
        Parameters:
        closeables - the objects to close.

      • closeQuietly

        public static void closeQuietly​(java.io.Closeable closeable)
        Closes the given Closeable quietly by ignoring IOException.
        Parameters:
        closeable - The resource to close.
        Since:
        1.1.0

      • readFully

        public static void readFully​(Input in,
                             long position,
                             byte[] buffer,
                             int offset,
                             int length)
                      throws java.io.IOException
        Does the readFully based on Input's positioned read. This does not change the current offset of the stream and is thread-safe.
        Parameters:
        in - the input source.
        position - the given position.
        buffer - the buffer to be read.
        length - the maximum number of bytes to read.
        offset - the start offset in array buffer.
        Throws:
        java.io.IOException - if an I/O error occurs.

      • readFully

        public static void readFully​(java.io.InputStream in,
                             byte[] buf,
                             int off,
                             int len)
                      throws java.io.IOException
        Does the readFully based on the Input read.
        Parameters:
        in - the input stream of bytes.
        buf - the buffer to be read.
        off - the start offset in array buffer.
        len - the maximum number of bytes to read.
        Throws:
        java.io.IOException - if an I/O error occurs.
