Methods Summary
public void	close() Closes this channel. throws IOException If an I/O error occurs todo Implement this java.nio.channels.Channel method getIOChannel().socket().close(); getIOChannel().close();
public void	close(boolean force) if (isOpen() || force ) close();
public boolean	flush(boolean block, java.nio.channels.Selector s, long timeout) returns true if the network buffer has been flushed out and is empty return boolean return true; //no network buffer in the regular channel
public java.lang.Object	getAttachment(boolean remove) Poller pol = getPoller(); Selector sel = pol!=null?pol.getSelector():null; SelectionKey key = sel!=null?getIOChannel().keyFor(sel):null; Object att = key!=null?key.attachment():null; if (key != null && att != null && remove ) key.attach(null); return att;
public org.apache.tomcat.util.net.SecureNioChannel.ApplicationBufferHandler	getBufHandler() getBufHandler return ApplicationBufferHandler todo Implement this org.apache.tomcat.util.net.SecureNioChannel method return bufHandler;

public boolean	isInitHandshakeComplete() isInitHandshakeComplete return boolean todo Implement this org.apache.tomcat.util.net.SecureNioChannel method return true;
public boolean	isOpen() Tells whether or not this channel is open. return true if, and only if, this channel is open todo Implement this java.nio.channels.Channel method return sc.isOpen();
public int	read(java.nio.ByteBuffer dst) Reads a sequence of bytes from this channel into the given buffer. param dst The buffer into which bytes are to be transferred return The number of bytes read, possibly zero, or -1 if the channel has reached end-of-stream throws IOException If some other I/O error occurs todo Implement this java.nio.channels.ReadableByteChannel method return sc.read(dst);
public void	reset() bufHandler.getReadBuffer().clear(); bufHandler.getWriteBuffer().clear();

public java.lang.String	toString() return super.toString()+":"+this.sc.toString();
public int	write(java.nio.ByteBuffer src) Writes a sequence of bytes to this channel from the given buffer. param src The buffer from which bytes are to be retrieved return The number of bytes written, possibly zero throws IOException If some other I/O error occurs todo Implement this java.nio.channels.WritableByteChannel method return sc.write(src);
