Method Details

init

public static SimucomstatusPackage init()

Creates, registers, and initializes the Package for this model, and for any others upon which it depends. Simple dependencies are satisfied by calling this method on all dependent packages before doing anything else. This method drives initialization for interdependent packages directly, in parallel with this package, itself.

Of this package and its interdependencies, all packages which have not yet been registered by their URI values are first created and registered. The packages are then initialized in two steps: meta-model objects for all of the packages are created before any are initialized, since one package's meta-model objects may refer to those of another.

Invocation of this method will not affect any packages that have already been initialized.
