Methods

Throws: IOException
If an I/O error occurs
Overrides:
read in class Reader
read
 public int read(char cbuf[],
                 int off,
                 int len) throws IOException
Read characters into a portion of an array.

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
Overrides:
read in class Reader
skip
 public long skip(long ns) throws IOException
Skip characters.

Throws: IOException
If an I/O error occurs
Overrides:
skip in class Reader
ready
 public boolean ready()
Tell whether this stream is ready to be read. String readers are always ready to be read.

Overrides:
ready in class Reader
markSupported
 public boolean markSupported()
Tell whether this stream supports the mark() operation, which it does.

Overrides:
markSupported in class Reader
mark
 public void mark(int readAheadLimit) throws IOException
Mark the present position in the stream. Subsequent calls to reset() will reposition the stream to this point.

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

Throws: IOException
If an I/O error occurs
Overrides:
reset in class Reader
close
 public void close()
Close the stream.

Overrides:
close in class Reader
