channelTable
protected java.util.Vector channelTable
- This is the actual table. If you need to synchronize across multiple
calls to this class, you may synchronize on this object.
Internally, all synchronization is done on this object.
Maybe this should be replaced with a public Object, and it should be used for all locking?

| Method Detail |
add
public void add(java.lang.String channelID, java.lang.String URLPrefix, java.lang.String servletID)
- Add a new channel. The new channel is not enabled and has
no TransactionFilters.
add
public void add(Channel channel)
- Add a new channel. The new channel is not enabled and has
no TransactionFilters.
delete
public void delete(java.lang.String channelID)
- Delete a channel.
getChannelIDs
public java.lang.String[] getChannelIDs()
- Returns the identifier names of all the channels currently in
the ChannelTable.
getChannelByID
public Channel getChannelByID(java.lang.String channelID)
- Return the Channel for the given identification
name. Returns null if not found.
findID
public Channel findID(java.lang.String channelID)
- Return the Channel for the given identification
name. Returns null if not found.
Warning: this method does not synchronize on channelTable.
The caller must synchronize on it.
Normally you will want to synchronize on it,
call this method to look up a Channel,
modify the Channel or the
table itself, then release the lock on channelTable. That way you
know that the table will not change between the time you fetch an
entry to the time you modify the entry or the table.
getChannelByURLPrefix
public Channel getChannelByURLPrefix(java.lang.String urlPrefix)
- Return the Channel for the given URL prefix.
Returns null if not found.
findURLPrefix
public Channel findURLPrefix(java.lang.String URL)
- Search the set of channels for one whose URLPrefix matches the
beginning of the given URL. Returns null if not found.
If you are extending this class, you should use this method to
determine which channel applies to a request URL.
The Channel returned is a reference to the object stored in
the table, so any changes made to it are also made to the working
instance in the table.
Warning: this method does not synchronize on channelTable. The caller must synchronize on it. Normally you will want to synchronize on it, call this method to look up a Channel, modify the Channel or the table its self, then release the lock on channelTable. That way you know that the table will not change between the time you fetch an entry to the time you modify the entry or the table.
toString
public java.lang.String toString()
- Return a multi-line string listing the channel ids.
