    Reads characters into a portion of an array.
    Specified by:

    Parameters:
    cbuf - Destination buffer
    off - Offset at which to start writing characters
    len - Maximum number of characters to read
    Returns:
    The number of characters read, or -1 if the end of the stream has been reached
    Throws:
    IOException - If an I/O error occurs
    IndexOutOfBoundsException - If an I/O error occurs

  • read

    public int read(char[] cbuf,
                int off,
                int len)
         throws IOException
    Reads characters into a portion of an array.
    Specified by:
    read in class Reader
    Parameters:
    cbuf - Destination buffer
    off - Offset at which to start writing characters
    len - Maximum number of characters to read
    Returns:
    The number of characters read, or -1 if the end of the stream has been reached

  • read

    public int read(char[] cbuf,
                int off,
                int len)
         throws IOException
    Reads characters into a portion of an array.
    Specified by:
    read in class Reader
    Parameters:
    cbuf - Destination buffer
    off - Offset at which to start writing characters
    len - Maximum number of characters to read
    Returns:
    The number of characters read, or -1 if the end of the stream has been reached
    Throws:
    IOException - If an I/O error occurs
    IndexOutOfBoundsException - If an I/O error occurs

method:skip(long) [NONE]

  • skip

    public long skip(long ns)
          throws IOException
    Skips the specified number of characters in the stream. Returns the number of characters that were skipped.

    The ns parameter may be negative, even though the skip method of the Reader superclass throws an exception in this case. Negative values of ns cause the stream to skip backwards. Negative return values indicate a skip backwards. It is not possible to skip backwards past the beginning of the string.

    If the entire string has been read or skipped, then this method has no effect and always returns 0.

    Overrides:
    skip in class Reader
    Parameters:
    ns - The number of characters to skip
    Returns:
    The number of characters actually skipped
    Throws:
    IOException - If an I/O error occurs

method:ready() [NONE]

  • ready

    public boolean ready()
              throws IOException
    Tells whether this stream is ready to be read.
    Overrides:
    ready in class Reader
    Returns:
    True if the next read() is guaranteed not to block for input
    Throws:
    IOException - If the stream is closed

method:markSupported() [NONE]

  • markSupported

    public boolean markSupported()
    Tells whether this stream supports the mark() operation, which it does.
    Overrides:
    markSupported in class Reader
    Returns:
    true if and only if this stream supports the mark operation.

method:mark(int) [NONE]

  • mark

    public void mark(int readAheadLimit)
          throws IOException
    Marks the present position in the stream. Subsequent calls to reset() will reposition the stream to this point.
    Overrides:
    mark in class Reader
    Parameters:
    readAheadLimit - Limit on the number of characters that may be read while still preserving the mark. Because the stream's input comes from a string, there is no actual limit, so this argument must not be negative, but is otherwise ignored.
    Throws:
    IllegalArgumentException - If readAheadLimit < 0
    IOException - If an I/O error occurs

method:reset() [NONE]

  • reset

    public void reset()
           throws IOException
    Resets the stream to the most recent mark, or to the beginning of the string if it has never been marked.
    Overrides:
    reset in class Reader
    Throws:
    IOException - If an I/O error occurs

method:close() [CHANGED]

  • close

    public void close()
    Closes the stream and releases any system resources associated with it. Once the stream has been closed, further read(), ready(), mark(), or reset() invocations will throw an IOException. Closing a previously closed stream has no effect. This method will block while there is another thread blocking on the reader.
    Specified by:
    close in interface CloseableAutoCloseable
    Specified by:
    close in interface AutoCloseableCloseable
    Specified by:
    close in class Reader

  • close

    public void close()
