MultipleBaseExpansionOperator

java.lang.Object
- net.sf.tweety.beliefdynamics.MultipleBaseExpansionOperator<T>

Type Parameters:

T - The type of formulas that this operator works on.

All Implemented Interfaces:

BaseExpansionOperator<T>

Direct Known Subclasses:

DefaultMultipleBaseExpansionOperator
```
public abstract class MultipleBaseExpansionOperator<T extends Formula>
extends java.lang.Object
implements BaseExpansionOperator<T>
```
This is the interface for a classic multiple belief base expansion operator, ie. an operator that takes some set of formulas and another set of formulas and expands the former by the latter.
