public Java.Nio.Channels.SelectionKey? Register (Java.Nio.Channels.Selector? sel, Java.Nio.Channels.Operations ops);[<Android.Runtime.Register("register", "(Ljava/nio/channels/Selector;I)Ljava/nio/channels/SelectionKey;", "")>]
member this.Register : Java.Nio.Channels.Selector * Java.Nio.Channels.Operations -> Java.Nio.Channels.SelectionKeyParameters
- sel
- Selector
The selector with which this channel is to be registered
- ops
- Operations
The interest set for the resulting key
Returns
A key representing the registration of this channel with the given selector
- Attributes
Exceptions
if the channel is closed.
if the channel is in blocking mode.
if this channel does not have the same provider as the given selector.
if this channel is registered but its key has been canceled.
if the operation given is not supported by this channel.

An invocation of this convenience method of the form

behaves in exactly the same way as the invocation
<blockquote>sc.#register(java.nio.channels.Selector,int,java.lang.Object) register(sel, ops, null)</blockquote>

Remarks
Registers this channel with the given selector, returning a selection key.
If this channel is currently registered with the given selector then the selection key representing that registration is returned. The key's interest set will have been changed to ops, as if by invoking the SelectionKey#interestOps(int) interestOps(int) method. If the att argument is not null then the key's attachment will have been set to that value. A CancelledKeyException will be thrown if the key has already been cancelled.
Otherwise this channel has not yet been registered with the given selector, so it is registered and the resulting new key is returned. The key's initial interest set will be ops and its attachment will be att.
This method may be invoked at any time. If this method is invoked while a selection operation is in progress then it has no effect upon that operation; the new registration or change to the key's interest set will be seen by the next selection operation. If this method is invoked while an invocation of #configureBlocking(boolean) configureBlocking is in progress then it will block until the channel's blocking mode has been adjusted.
If this channel is closed while this operation is in progress then the key returned by this method will have been cancelled and will therefore be invalid.
