The methods of the
are deliberately similar to the methods of the
java.io.InputStream class. However rather than working with bytes, they work with chars.
read() method reads a single character
(which may may take between one and four bytes depending on the character set) and returns the character as an int between 0 and 65535. It returns -1 if the end of stream is seen.
public int read() throws IOException
You can also read many characters into an array of chars. These methods return the number of bytes successfully read or -1 if the end of stream occurs.
public int read(char text) throws IOException public abstract int read(char text, int offset, int length) throws IOException
read() methods block until some input is
available, an I/O error occurs, or the end of the stream is reached.
You can skip a certain number of characters. This method also blocks until some characters are available. It returns the number of characters skipped or -1 if the end of stream is reached.
public long skip(long n) throws IOException
ready() method returns true if the reader is
ready to be read from, false if it isn't. Generally this means
the underlying stream has available data.
public boolean ready() throws IOException
Readers may or may not support marking and resetting, like input streams.
public boolean markSupported() public void mark(int readAheadLimit) throws IOException public void reset() throws IOException
close() method closes the
Reader and releases any resources associated with
public abstract void close() throws IOException
