Overview¶

Access modifiers are keywords used to specify the declared accessibility of a member or a type. The four access modifiers:

public
protected
internal
private

Jetfire allows access modifiers to be dynamic. Typically in an OO language access modifiers (including C#) are fixed in the code. The access modifiers can not be changed without changing the source code.

Jetfire allows access modifiers to changed dynamically using 4 separate mechanisms:

States Construct
Access Construct using a boolean method as a constraint
- See 'Basket' example.
Access Construct using a role as a constraint
- See 'Approval Request' example.
Access Construct and States Construct
- See 'Advanced Approval Request' example.

Note: For code compilation Jetfire only uses the standard access modifiers (public, protected, internal and private). That is, the standard access modifiers determine if the object, such as workflow, property, method or field, is visible to other code. If the object is referenced in other code where it is not visible a compilation error will result.

The dynamic access modifiers determine if access is allowed at run time.
