Enum Constant Summary

Enum Constants
Enum Constant and Description
`EQUAL` True if whether at least one answer has a value that is equal to the enableWhen answer.
`EXISTS` True if whether an answer exists is equal to the enableWhen answer (which must be a boolean).
`GREATER_OR_EQUAL` True if whether at least no answer has a value that is greater or equal to the enableWhen answer.
`GREATER_THAN` True if whether at least no answer has a value that is greater than the enableWhen answer.
`LESS_OR_EQUAL` True if whether at least no answer has a value that is less or equal to the enableWhen answer.
`LESS_THAN` True if whether at least no answer has a value that is less than the enableWhen answer.
`NOT_EQUAL` True if whether at least no answer has a value that is equal to the enableWhen answer.
`NULL` added to help the parsers with the generic types

- Method Detail
  - values
```
public static Questionnaire.QuestionnaireItemOperator[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (Questionnaire.QuestionnaireItemOperator c : Questionnaire.QuestionnaireItemOperator.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static Questionnaire.QuestionnaireItemOperator valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - fromCode
