public CharArrayReader(char[] buf)
buf
- Input buffer (not copied)public CharArrayReader(char[] buf, int offset, int length)
buf
- Input buffer (not copied)
offset
- Offset of the first char to read
length
- Number of chars to readMethod Detail |
public int read() throws IOException
public int read(char[] b, int off, int len) throws IOException
b
- Destination buffer
off
- Offset at which to start storing characters
len
- Maximum number of characters to readpublic long skip(long n) throws IOException
n
- The number of characters to skippublic boolean ready() throws IOException
public boolean markSupported()
public void mark(int readAheadLimit) throws IOException
readAheadLimit
- Limit on the number of characters that may be
read while still preserving the mark. Because
the stream's input comes from a character array,
there is no actual limit; hence this argument is
ignored.public void reset() throws IOException
public void close()
