    a value of boolean
  - everyMinute
```
public void everyMinute()
```
    Description copied from class: AbstractMessageReceiver
    
    Utility method executed precisely every minute. A component can overwrite the method to put own code to be executed at the regular intervals of time.
    Note, no extensive calculations should happen in this method nor long lasting operations. It is essential that the method processing does not exceed 1 minute. The overriding method must call the the super method first and only then run own code.
    
    Overrides:
    
    everyMinute in class AbstractMessageReceiver
  - hashCodeForPacket
```
public int hashCodeForPacket(Packet packet)
```
    Description copied from class: AbstractMessageReceiver
    This method decides how incoming packets are distributed among processing threads. Different components needs different distribution to efficient use all threads and avoid packets re-ordering.
    If there are N processing threads, packets are distributed among threads using following code:
```
 int threadNo = Math.abs(hashCodeForPacket(packet) % N);
 
```
    For a PubSub component, for example, a better packets distribution would be based on the PubSub channel name, for SM a better distribution is based on the destination address, etc....
    Overrides:
    
    hashCodeForPacket in class AbstractMessageReceiver
    
    Parameters:
    
    packet - is a Packet which needs to be processed by some thread.
    
    Returns:
    
    a hash code generated for the input thread.
  - initBindings
```
public void initBindings(Bindings binds)
```
    Description copied from class: BasicComponent
    
    Initialize a mapping of key/value pairs which can be used in scripts loaded by the server
    
    Overrides:
    
    initBindings in class BasicComponent
    
    Parameters:
    
    binds - A mapping of key/value pairs, all of whose keys are Strings.
  - initializationCompleted
```
public void initializationCompleted()
```
    Description copied from interface: ServerComponent
    
    Method is called by MessageRouter when all the startup components of the server have been loaded and configured through setProperties(...) call. At this point the whole server should be loaded and functional, except initializations taking place in this routine.
    
    Specified by:
    
    initializationCompleted in interface ServerComponent

  - processPacket
```
public void processPacket(Packet packet)
```
    Description copied from class: AbstractMessageReceiver
    
    This is the main Packet processing method. It is called concurrently from many threads so implementing it in thread save manner is essential. The method is called for each packet addressed to the component.
    Please note, the Packet instance may be processed by different parts of the server, different components or plugins at the same time. Therefore this is very important to tread the Packet instance as unmodifiable object.
    Processing in this method is asynchronous, therefore there is no result value. If there are some 'result' packets generated during processing, they should be passed back using addOutPacket(Packet) method.
    
    Specified by:
    
    processPacket in class AbstractMessageReceiver
    
    Parameters:
    
    packet - is an instance of the Packet class passed for processing.

  - getDefaults
```
public Map<String,Object> getDefaults(Map<String,Object> params)
```
    Description copied from class: AbstractMessageReceiver
    
    Returns default configuration settings for the component as a Map with keys as configuration property IDs and values as the configuration property values. All the default parameters returned from this method are later passed to the setProperties(...) method. Some of them may have changed value if they have been overwritten in the server configuration. The configuration property value can be of any of the basic types: int, long, boolean, String.
    
    Specified by:
    
    getDefaults in interface Configurable
    
    Overrides:
    
    getDefaults in class AbstractMessageReceiver
    
    Parameters:
    
    params - is a Map with some initial properties set for the starting up server. These parameters can be used as a hints to generate component's default configuration.
    
    Returns:
    
    a Map with the component default configuration.
  - getStatistics
```
public void getStatistics(StatisticsList list)
```
    Description copied from class: AbstractMessageReceiver
    Method returns component statistics. Please note, the method can be called every second by the server monitoring system therefore no extensive or lengthy calculations are allowed. If there are some statistics requiring lengthy operations like database access they must have Level.FINEST assigned and must be put inside the level guard to prevent generating them by the system monitor. The system monitor does not collect FINEST statistics.
    Level guard code looks like the example below:
```
 if (list.checkLevel(Level.FINEST)) {
   // Some CPU intensive calculations or lengthy operations
   list.add(getName(), "Statistic description", stat_value, Level.FINEST);
 }

 
```
    This way you make sure your extensive operation is not executed every second by the monitoring system and does not affect the server performance.

    Overrides:
    
    getStatistics in class AbstractMessageReceiver
