Supported Mosel Types

There are restrictions on what entity types can be persisted and manipulated.

The following table describes these restrictions.

Mosel Entity Type	Supported
Basic types (boolean, integer, real, string)	Yes
MP types (mpvar, linctr)	Yes
Sets (boolean, integer, string)	Yes
Lists	No
Arrays—(boolean, integer, real, string, mpvar, linctr)	Yes
Arrays indexed by real numbers	No
Arrays arrays indexed by valid sets (boolean, integer, string)	Yes
Sparse array (dynamic or hashmap array)	Yes
Records	No
Constants	Yes
User-defined types (including nested types)	No
Parameters	Yes
Types defined in modules	No
mmproblem type	No
Anonymous constraints	No

Note Xpress Insight does not support nested types. Where a type is otherwise unsupported (such as nlctr), it can still be used in a model; unsupported types are ignored by Xpress Insight and are not captured as input or results data.

Note Entities declared locally within a procedure or function are not visible to Xpress Insight.

Note Custom DSO modules required by the model should be pre-installed into the MOSEL_DSO directory for each execution worker. By default, the MOSEL_DSO directory is <xpressdir>\dso. Custom types defined by a module are not currently supported by Xpress Insight. If custom types are used in the model, they will not be captured in the input or results data. This includes custom types from core modules including quadratic and non-linear variables and constraint types, text/date types, and mmjob types. The Model type provided by mmjobs is not directly supported.

Differences in the treatment of scalar and parameter types

Scalar values, like all input data, are undefined at the start of the execution of a model. Scalar values are injected at insightpopulate for scenario executions.

Parameters are passed to the model and are available to the model from the beginning of its execution. Parameters therefore provide a means of configuring how a scenario is loaded, such as determining which file or data connection to use.
