| Method Summary | |
| public void | close()
Close the stream. | | public void | mark(int readAheadLimit)
Mark the present position in the stream. | | public boolean | markSupported()
Tell whether this stream supports the mark() operation, which it does. | | public int | read()
Read a single character. | | public int | read(char cbuf, int off, int len)
Read characters into a portion of an array. | | public boolean | ready()
Tell whether this stream is ready to be read. | | public void | reset()
Reset the stream to the most recent mark, or to the beginning of the
string if it has never been marked. | | public long | skip(long ns)
Skip characters. |
| StringReader | | public StringReader(String s)(Code) | | Create a new string reader.
Parameters:
s - String providing the character stream. |
| close | | public void close()(Code) | | Close the stream.
|
| mark | | public void mark(int readAheadLimit) throws IOException(Code) | | 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 beread while still preserving the mark. Becausethe stream's input comes from a string, thereis no actual limit, so this argument must notbe negative, but is otherwise ignored.
exception:
IllegalArgumentException - If readAheadLimit is < 0
exception:
IOException - If an I/O error occurs |
| markSupported | | public boolean markSupported()(Code) | | Tell whether this stream supports the mark() operation, which it does.
|
| read | | public int read() throws IOException(Code) | | Read a single character.
The character read, or -1 if the end of the stream has beenreached
exception:
IOException - If an I/O error occurs |
| read | | public int read(char cbuf, int off, int len) throws IOException(Code) | | Read characters into a portion of an array.
Parameters:
cbuf - Destination buffer
Parameters:
off - Offset at which to start writing characters
Parameters:
len - Maximum number of characters to read The number of characters read, or -1 if the end of thestream has been reached
exception:
IOException - If an I/O error occurs |
| ready | | public boolean ready() throws IOException(Code) | | Tell whether this stream is ready to be read.
True if the next read() is guaranteed not to block for input
exception:
IOException - If the stream is closed |
| reset | | public void reset() throws IOException(Code) | | Reset the stream to the most recent mark, or to the beginning of the
