There are several different kinds of types. Record/Class Types and Array Types are described below. Also there are function types and types of classes that contain local classes.

1 Record/Class Type

A record/class type in Modelica is conceptually the set of all record values of that record type, where each value contains named field values for the fields of that record.

2 Array Type

An array type is conceptually a set of array values, where each array value can be considered as a set of pairs (array-element-index, array-value) analogous to the set of pairs (field-name, field value) that make up a record value.
