## Class QuadLeftHandSide<A,​B,​C,​D>

- java.lang.Object
- - org.optaplanner.core.impl.score.stream.drools.common.QuadLeftHandSide<A,​B,​C,​D>

- Type Parameters:
    `A` - generic type of the first resulting variable
    `B` - generic type of the second resulting variable
    `C` - generic type of the third resulting variable
    `D` - generic type of the fourth resulting variable

      public final class QuadLeftHandSide<A,​B,​C,​D>
      extends Object

  Represents the left hand side of a Drools rule, the result of which are four variables. For more, see `UniLeftHandSide` and `BiLeftHandSide`.
