Method Detail

getImportedModels
```
public Collection<SModelReference> getImportedModels()
```
Returns:

nothing but snapshot of models explicitly listed as imports of the initial model, in no particular order. XXX and likely without null values.

addModelImport

public void addModelImport(@NotNull
                           SModelReference modelToImport)

removeModelImport

public void removeModelImport(@NotNull
                              SModelReference modelToRemove)

getUsedLanguages

public Collection<SLanguage> getUsedLanguages()

addUsedLanguage

public void addUsedLanguage(@NotNull
                            SLanguage language)

removeUsedLanguage

public void removeUsedLanguage(@NotNull
                               SLanguage language)

getUsedDevKits
```
public Collection<SModuleReference> getUsedDevKits()
```
Returns:

snapshot of devkits listed as used by the model, in no particular order

addUsedDevKit

public void addUsedDevKit(@NotNull
                          SModuleReference devkit)

getLanguagesEngagedOnGeneration

public Collection<SLanguage> getLanguagesEngagedOnGeneration()

copyImportedModelsFrom
```
public void copyImportedModelsFrom(@NotNull
                                   SModel other)
```
Use another model as source for necessary imports. Copies immediate imports of other models.

Parameters:

other - model to copy imports from

copyUsedLanguagesFrom
```
public void copyUsedLanguagesFrom(@NotNull
                                  SModel other)
```
Use another model as source for necessary used languages. Note, only directly imported languages (not devkits nor closure of visible)

Parameters:

other - model to copy used languages from

copyEmployedDevKitsFrom

public void copyEmployedDevKitsFrom(@NotNull
                                    SModel other)

Use another model as source for necessary devkits.

Parameters:: other - model to copy devkit imports from

copyLanguageEngagedOnGeneration
```
public void copyLanguageEngagedOnGeneration(@NotNull
                                            SModel other)
```
Use another model as specification of languages that are engaged during generation.

Parameters:

other - model to copy engaged languages from

clearImportedModels
```
public void clearImportedModels()
```

clearEmployedDevKits
```
public void clearEmployedDevKits()
```

clearUsedLanguages
```
public void clearUsedLanguages()
```
