StringReader
public StringReader(String s)
- Create a new string reader.
read
public int read() throws IOException
- Read a single character.
- Returns:
- The character 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
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() throws IOException
- Tell whether this stream is ready to be read.
- Returns:
- True if the next read() is guaranteed not to block for input
- Throws:
- IOException - If the stream is closed
- 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
