Precondition Configuration

Preconditions can be configured in a several ways:

• A result of a precondition can be negated 
• A result of a precondition can be combined with a result of previous preconditions using the following ways:
  • Discard the result of previous precondition (Results of the previous preconditions are not taken into account)
  • AND (All of the preconditions have to be true to allow execute a post function)
  • OR (Only one of the preconditions has to be true to allow execute a post function)

Precondition Usage

There are several ways in which preconditions can be evaluated in the context of a post function:

• Ignore precondition (By default every precondition is ignored. It means that post function will be always performed)
• True (Precondition must be true to execute a post function)
• False (Precondition must be false to execute a post function)
