public abstract class BaseToolFactory extends Object
Base class for all tool factories.

Extensions of this class should:

  • Konstruktordetails

    • BaseToolFactory

      public BaseToolFactory()
      All subclasses should have an empty constructor

  • Methodendetails

    • createArtifactSerializersMap

      public Map<String,ArtifactSerializer<?>> createArtifactSerializersMap()
      Creates a Map with pairs of keys and ArtifactSerializer. The models implementation should call this method from BaseModel#createArtifactSerializersMap.

      The base implementation will return a HashMap that should be populated by subclasses.

    • createArtifactMap

      public Map<String,Object> createArtifactMap()
      A model's implementation should call this constructor that creates a model programmatically.

      The base implementation will return a HashMap that should be populated by subclasses.

      Gibt zurück:
      Retrieves a Map with pairs of keys and objects.

    • createManifestEntries

      public Map<String,String> createManifestEntries()
      Gibt zurück:
      Retrieves the manifest entries to be added to the model manifest.

    • validateArtifactMap

      public abstract void validateArtifactMap() throws InvalidFormatException
      Validates the parsed artifacts.

      Note: Subclasses should generally invoke super.validateArtifactMap at the beginning of this method.

      Löst aus:
      InvalidFormatException - Thrown if validation found invalid states.

    • create

      public static BaseToolFactory create(String subclassName, ArtifactProvider artifactProvider) throws InvalidFormatException
      Instantiates a BaseToolFactory via a given subclassName.
      Parameter:
      subclassName - The class name used for instantiation. The ExtensionLoader mechanism is applied to load the requested subclassName.
      artifactProvider - The ArtifactProvider to be used.
      Gibt zurück:
      A valid BaseToolFactory instance.
      Löst aus:
      InvalidFormatException - Thrown if the ExtensionLoader mechanism failed to create the factory associated with subclassName.

    • create

      public static BaseToolFactory create(Class<? extends BaseToolFactory> factoryClass, ArtifactProvider artifactProvider) throws InvalidFormatException
      Instantiates a BaseToolFactory via a given subclassName.
      Parameter:
      factoryClass - The class used for instantiation. The no-arg constructor of that class will be used to create and init the resulting object.
      artifactProvider - The ArtifactProvider to be used.
      Gibt zurück:
      A valid BaseToolFactory instance.
      Löst aus:
      InvalidFormatException - Thrown if the ExtensionLoader mechanism failed to create the factory associated with subclassName.
