trait CompositionOperator extends Operator
Defines interface of class/object that defines a composition operator. Unlike other operators, these operators are more complex and new to inform sub-nodes in syntax tree of values before evaluating its current node. This is performed by updating the map "logicOperatorToValue" which is passed on to sub-nodes. Invoked method has to be "composeOperator" and overloading this method doesn't work.

Abstract Value Members
- abstract def checkInputs(conditions: Array[JsonLogicCore]): Unit
Checks if conditions satisfies this operator's constraints.
Checks if conditions satisfies this operator's constraints. Should throw an exception if not.
- abstract def composeOperator(values: Array[Any], logicArr: Array[JsonLogicCore], conditionCaller: ComposeLogic, reduceLogic: EvaluatorLogic, logicOperatorToValue: Map[ComposeLogic, Map[String, Any]]): Any
Returns value by this composition operator.
Returns value by this composition operator.
- returns
operated value by operator.

- def evalOperator(conditionCaller: ComposeLogic, reduceLogic: EvaluatorLogic, logicOperatorToValue: Map[ComposeLogic, Map[String, Any]]): Any
Returns evaluated result of corresponding condition (internal node in syntax tree).
Returns evaluated result of corresponding condition (internal node in syntax tree). This method carries a map of map of (composition_operator -> map(variable_name -> variable_value)) to fetch the value of variable (depends on the composition_operator and the values this composition_operator is applied to). This map of map is necessary as a composition_operator can be composed with another composition_operator which requires to be able to distinguish between values which composition_operator they belong to.
- returns
