  - ### Method Detail

    - #### getLanguages

          public String[] getLanguages()

      Description copied from interface: `LanguagePrecondition`
      Gets the languages that satisfy this precondition. This will be an array of ISO language identifiers. For this precondition to be satisfied, the document's language must be subsumed by one of these identifiers (for example, en-GB is subsumed by en).

      Note that if the document's language is unknown, the value of the `default` property determines whether this precondition is satisfied.

      Specified by:
        `getLanguages` in interface `LanguagePrecondition`
      Returns:
        the languages that satisfy this precondition
      See Also:
        `LanguagePrecondition.getLanguages()`

    - #### setLanguages

          public void setLanguages(String[] aLanguages)

      Description copied from interface: `LanguagePrecondition`
      Sets the languages that satisfy this precondition. This will be an array of ISO language identifiers. For this precondition to be satisfied, the document's language must be subsumed by one of these identifiers (for example, en-GB is subsumed by en).

      Note that if the document's language is unknown, the value of the `default` property determines whether this precondition is satisfied. The ISO language identifiers are cannonicalized by lower-casing them and replacing underscores with hyphens. Also, if any of the identifiers are x-unspecified, the array is replaced with an array of just one element: x-unspecified, since all languages are defined to match that one.

      Specified by:
        `setLanguages` in interface `LanguagePrecondition`
      Parameters:
        `aLanguages` - the languages that satisfy this precondition
      See Also:
        `LanguagePrecondition.setLanguages(java.lang.String[])`

    - #### setComparisonValue

          public void setComparisonValue(Object aValue)

      Description copied from interface: `SimplePrecondition`
      Sets the literal value to which features' values will be compared.
      Specified by:
        `setComparisonValue` in interface `SimplePrecondition`
      Overrides:
        `setComparisonValue` in class `SimplePrecondition_impl`
      Parameters:
        `aValue` - the comparison value, which must be a String, Integer, Float, Boolean, or an array of one of those four types.
      See Also:
        `SimplePrecondition.setComparisonValue(java.lang.Object)`

    - #### setFeatureName

          public void setFeatureName(String aFeatureName)

      Description copied from interface: `SimplePrecondition`
      Sets the name of the feature to be tested.
      Specified by:
