Method Detail

### getOperatorSymbol

    public String getOperatorSymbol()

  Returns the symbol representing the operator

  Specified by:
    `getOperatorSymbol` in class `BinaryOperator`

### apply

    public Object apply(Object pLeft,
                        Object pRight,
                        Object pContext,
                        Logger pLogger)

  Applies the operator to the given value

  Specified by:
    `apply` in class `BinaryOperator`
  Throws:
    `ELException`

### shouldEvaluate

    public boolean shouldEvaluate(Object pLeft)

  Returns true if evaluation is necessary given the specified Left value. The And/OrOperators make use of this

  Overrides:
    `shouldEvaluate` in class `BinaryOperator`

### shouldCoerceToBoolean

    public boolean shouldCoerceToBoolean()

  Returns true if the operator expects its arguments to be coerced to Booleans. The And/Or operators set this to true.

  Overrides:
    `shouldCoerceToBoolean` in class `BinaryOperator`
