Detailed Description

Lists all Terms.

OTX terms represent syntactic expressions which can be evaluated in order to yield a value. The resulting value of a term can be a simple value (e.g. an integer in the OTX Integer case) or a reference to complex data (e.g. a reference to a list in the OTX List case). Terms are required in various places in the data model, when a value needs to be computed which is then e.g. assigned to a variable, used as an input parameter for a procedure call, or used as the condition truth value in a branch, etc. Every OTX term is categorized according to its return type.

Note

OTX terms never have side-effects – this means that the arguments of a term will not be changed by term evaluation.

The abstract OTX Core terms are extensible. This means that OTX extensions may derive new terms from any of the abstract term categories defined in the OTX Core.
