## Interface TypePriorities

- All Superinterfaces:
    Cloneable, MetaDataObject, Serializable, XMLizable

      public interface TypePriorities
      extends MetaDataObject

  A declaration of priorities between CAS Types. Type priority can be a basis for ordering feature structures within an index - see `FsIndexDescription`.

  This object implements `MetaDataObject`, which implements `XMLizable`, so it can be serialized to and deserialized from an XML element.

  TypePriorities can declare that they `import` other TypePriorities. At runtime, these imports will be resolved to create a single logical TypePriorities object.

  Note that type priorities imports are not automatically resolved when a TypePriorities object is deserialized from XML. To resolve the imports, call the `resolveImports()` method. Import resolution is done automatically when a CAS is created using a TypePriorities object.

  TypePriorities declarations can optionally be assigned a `name`, `description`, `vendor`, and `version`. It is recommended that these properties be set on any TypePriorities declaration that is meant to be shared by (imported by) multiple components.

      Resolves any import declarations in this Type Priorities declaration, adding the imported `TypePriorityList` objects directly onto this TypePriorities object's `priorityLists`. The import elements are then deleted, so this results in a structure that is equivalent to the imported elements having been defined locally.
      Throws:
        `InvalidXMLException` - if either the import target does not exist or is invalid

    - #### resolveImports

      Resolves any import declarations in this Type Priorities declaration, adding the imported `TypePriorityList` objects directly onto this TypePriorities object's `priorityLists`. The import elements are then deleted, so this results in a structure that is equivalent to the imported elements having been defined locally.
      Parameters:
        `aResourceManager` - the Resource Manager used to locate type priorities XML files imported by name. For example, the path in which to locate these type priorities XML files can be set via the `ResourceManager.setDataPath(String)` method.

    - #### resolveImports

          void resolveImports(Collection<String> aAlreadyImportedPriorityListURLs,

      Resolves any import declarations in this Type Priorities declaration, adding the imported `TypePriorityList` objects directly onto this TypePriorities object's `priorityLists`. The import elements are then deleted, so this results in a structure that is equivalent to the imported elements having been defined locally.

      This version is used internally to resolve nested imports.

      Parameters:
        `aAlreadyImportedPriorityListURLs` - URLs of already imported type priorities, so we don't import them again.
        `aResourceManager` - the Resource Manager used to locate type priorities XML files imported by name. For example, the path in which to locate these type priorities XML files can be set via the `ResourceManager.setDataPath(String)` method.
      Throws:
        `InvalidXMLException` - if either the import target does not exist or is invalid
