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

### shouldEvaluate

    public boolean shouldEvaluate(java.lang.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()
