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. Note: 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.
