Method Detail

read

public int read(char[] buf,
                int offset,
                int len)
         throws IOException

Description copied from class: Reader

Read characters into a portion of an array. This method will block until some input is available, an I/O error occurs, or the end of the stream is reached.

Specified by:

read in class Reader

Parameters:

buf - Destination buffer

offset - Offset at which to start storing 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

ready

public boolean ready()
              throws IOException

Description copied from class: Reader

Tell 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, false otherwise. Note that returning false does not guarantee that the next read will block.

Throws:

IOException - If an I/O error occurs

close

public void close()
           throws IOException

Description copied from class: Reader

Close the stream. Once a stream has been closed, further read(), ready(), mark(), or reset() invocations will throw an IOException. Closing a previously-closed stream, however, has no effect.

Specified by:

close in class Reader

Throws:

IOException - If an I/O error occurs
