FilterTable (Atavism Server API

Direct Known Subclasses:

DefaultFilterTable
```
public abstract class FilterTable
extends java.lang.Object
```
Collection of filters with optimized message matching. Implement a sub-class to provide custom optimization for certain kinds of filters. If a filter does not provide a FilterTable, then a DefaultFilterTable is used.
A filter table is used by MessageAgent to collect filters together so message matching can be optimized. Filters are placed into one of four filter table instances:
send: filters matched when agent sends a message
receive: filter matched when message received from another agent
responder send: filters matched when agent sends an RPC
responder receive: filters matched when RPC received from another agent
Each Filter instance can provide FilterTables to use. If none are provided (they return 'null'), then a DefaultFilterTable is used.
