STEP data ultimately consists of instances of EXPRESS defined entities. These entities are mapped to Java classes by the express2java compiler, and implement the EntityInstance interface.
This package includes the Model class which defines the unit of persistance.
The contents of a Model can be written to or read from a STEP Part 21
file using the Part21Writer and Part21Parser
The data is contained in models. A Model has
zero or more sets of
STEP entity instances called populations, which are implemented as subtypes
of the PopulationBase class.
The population provides the methods to create and find entity instances.
The Domain, Attribute and related classed provide a view of to
EXPRESS information model, and can be used to access the STEP data in a
late-bound fashion.
