mark(int)

Mark the present position in the stream.

markSupported()

Tell whether this stream supports the mark() operation, which it does.

read()

Read a single character.

read(char[], int, int)

Read characters into a portion of an array.

Tell whether this stream is ready to be read.

reset()

Reset the stream to the most recent mark, or to the beginning of the string if it has never been marked.

skip(long)

Skip characters.

 public StringReader(String s)

Create a new string reader.

Throws: IOException

If an I/O error occurs

Overrides:

read in class Reader

 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

 public long skip(long ns) throws IOException

Skip characters.

Throws: IOException

If an I/O error occurs

Overrides:

 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

 public boolean markSupported()

Tell whether this stream supports the mark() operation, which it does.

Overrides:

markSupported in class Reader

 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

 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

 public void close()

Close the stream.
