### Working with Python *enumerations* { #working-with-python-enumerations }

The value of the *path parameter* will be an *enumeration member*.

#### Compare *enumeration members* { #compare-enumeration-members }

You can compare it with the *enumeration member* in your created enum `ModelName`:

/**
 * An SPI interface to extend Maven with new enum values for extensible enumerations.
 * <p>
 * Maven uses extensible enumerations to allow plugins and extensions to add new values
 * to various categories like languages, scopes, and packaging types. This interface is the
 * base for all providers that register such extensions.

Créez ensuite des attributs de classe avec des valeurs fixes, qui seront les valeurs autorisées pour cette énumération.

### Trabalhando com os *enumeration* do Python

O valor do *parâmetro da rota* será um *membro de enumeration*.

#### Compare *membros de enumeration*

Você pode comparar eles com o *membro de enumeration* no enum `ModelName` que você criou:

 * <h2>Relationship with Java compiler standard location</h2>
 * This enumeration is closely related to the {@link JavaFileManager.Location} enumerations.
 * A difference is that the latter enumerates input and output files, while {@code JavaPathType}
 * enumerates only input dependencies. Another difference is that {@code JavaPathType} contains
 * some enumeration values used only at runtime and therefore not available in {@code javax.tool},
