    • bind

      <BoundVar_> Child_ bind(org.drools.model.Variable<BoundVar_> boundVariable, Function<A,BoundVar_> bindingFunction)
      Bind a new variable. This call is safe for use outside accumulate() and groupBy(), unlike bind(Variable, Variable, BiFunction) etc.
      Type Parameters:
      BoundVar_ - generic type of the bound variable
      Parameters:
      boundVariable - the new variable
      bindingFunction - the function to apply to create the bound variable
      Returns:
      never null

    • bind

      <BoundVar_, LeftJoinVar_> Child_ bind(org.drools.model.Variable<BoundVar_> boundVariable, org.drools.model.Variable<LeftJoinVar_> leftJoinVariable, BiFunction<A,LeftJoinVar_,BoundVar_> bindingFunction)
      This must only be used in patterns that will eventually end up in accumulate() or groupBy(). Drools does not support binding 2+ variables outside of accumulate() or groupBy(). Disobeying will result in Drools NullPointerException at runtime.
      Type Parameters:
      BoundVar_ - generic type of the bound variable
      LeftJoinVar_ - generic type of the join variable
      Parameters:
      boundVariable - the new variable
      leftJoinVariable - the variable to use when creating the bound variable
      bindingFunction - the function to apply to create the bound variable
      Returns:
      never null

      <BoundVar_, LeftJoinVarA_, LeftJoinVarB_> Child_ bind(org.drools.model.Variable<BoundVar_> boundVariable, org.drools.model.Variable<LeftJoinVarA_> leftJoinVariableA, org.drools.model.Variable<LeftJoinVarB_> leftJoinVariableB, TriFunction<A,LeftJoinVarA_,LeftJoinVarB_,BoundVar_> bindingFunction)
      As defined by bind(Variable, Variable, BiFunction).
      Type Parameters:
      BoundVar_ - generic type of the bound variable
      LeftJoinVarA_ - generic type of the first join variable
      LeftJoinVarB_ - generic type of the second join variable
      Parameters:
      boundVariable - the new variable
      leftJoinVariableA - the first variable to use when creating the bound variable
      leftJoinVariableB - the second variable to use when creating the bound variable
      bindingFunction - the function to apply to create the bound variable
      Returns:
      never null

      As defined by bind(Variable, Variable, BiFunction).
      Type Parameters:
      BoundVar_ - generic type of the bound variable
      LeftJoinVarA_ - generic type of the first join variable
      LeftJoinVarB_ - generic type of the second join variable
      LeftJoinVarC_ - generic type of the third join variable
      Parameters:
      boundVariable - the new variable
      leftJoinVariableA - the first variable to use when creating the bound variable
      leftJoinVariableB - the second variable to use when creating the bound variable
      leftJoinVariableC - the third variable to use when creating the bound variable
      bindingFunction - the function to apply to create the bound variable
      Returns:
      never null
