ClientTracker.OperationQueue

java.lang.Object
- org.astrogrid.samp.client.ClientTracker.OperationQueue

Enclosing class:

ClientTracker
```
private static class ClientTracker.OperationQueue
extends java.lang.Object
```
Data structure for holding ClientOperation objects which (may) need to be applied in the future. Operations are dumped here if they cannot be performed immediately because the client in question is not (yet) known by this tracker. The hope is that the client will register at some point in the future and the pending operations can be applied then. However, this may never happen, so the queue maintains its own expiry system to throw out old events.

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`void`	`add(ClientTracker.ClientOperation op)` Add a new client operation which may get the opportunity to be performed some time in the future.
`void`	`apply(ClientTracker.TrackedClient client)` Apply any pending operations to given client.
`void`	`clear()` Removes all entries from this queue.
`void`	`discard(ClientTracker.TrackedClient client)` Discards any operations corresponding to a given client, presumably because the client is about to disappear.
`void`	`discardOld(long maxAge)` Throws away any pending operations which are older than a certain age, presumably in the expectation that their client will never register.
`ClientTracker.ClientOperation[]`	`getOperations()` Returns an array containing all the operations currently pending.

  - add
```
public void add(ClientTracker.ClientOperation op)
```
    Add a new client operation which may get the opportunity to be performed some time in the future.
    
    Parameters:
    
    op - oeration to add
  - apply
```
public void apply(ClientTracker.TrackedClient client)
```
    Apply any pending operations to given client. This client was presumably unavailable at the time such operations were queued.
    
    Parameters:
    
    client - client to apply pending operations to
  - discard
```
public void discard(ClientTracker.TrackedClient client)
```
    Discards any operations corresponding to a given client, presumably because the client is about to disappear.
    
    Parameters:
    
    client - client to forget about
  - discardOld
```
public void discardOld(long maxAge)
```
    Throws away any pending operations which are older than a certain age, presumably in the expectation that their client will never register.
    
    Parameters:
    
    maxAge - oldest operations (in milliseconds) permitted to remain in the queue
  - clear
```
public void clear()
```
    Removes all entries from this queue.
  - getOperations
```
public ClientTracker.ClientOperation[] getOperations()
```
    Returns an array containing all the operations currently pending.
    
    Returns:
    
    operation list
