Is there a term that describes the property of being synchronous vs asynchronous?
The term that most naturally comes to mind is "synchronicity", however I only see this term being use in psychology. I would like to use this term as a property label on APIs that I am documenting, however I want to see if there is already a term for this before just going with it. Does anyone have any documentation or examples of a term being used to describe this property?
Example of how it would be used as part of a specification:
Synchronicity: This API has both Synchronous and Asynchronous behaviors
Another way of asking this is that I would like to fill in the blank below.
As Idempotency is to Idempotent or Not Idempotent, _________ is to Synchronous or Asynchronous.
Clarification: This is intended to be used in published API specifications/documentation, not the documentation of the API within the source.
