## griffon.core
[Java] Interface ArtifactHandler

    griffon.core.ApplicationHandler
      griffon.core.ArtifactHandler

All Superinterfaces:
  ApplicationHandler

    public interface ArtifactHandler
    extends ApplicationHandler

The ArtifactHandler interface's purpose is to allow the analysis of conventions within a Griffon application.

An artifact is represented by the GriffonClass interface and this interface provides methods that allow artifacts to be identified, created and initialized.

Authors:
  Andres Almiray

Method Summary
`GriffonClass` | `findClassFor(String propertyName)` Finds an artifact by its property name.
`GriffonClass` | `getClassFor(Class clazz)` Finds an artifact if the target `clazz` is handled by this ArtifactHandler.
`GriffonClass` | `getClassFor(String fqnClassName)` Finds an artifact by class name if it represents a class that is handled by this ArtifactHandler.
`GriffonClass[]` | `getClasses()` Returns the set of all artifact classes this handler manages.
`String` | `getTrailing()` Get the trailing suffix that identifies the artifact.
`String` | `getType()` Get the type of artifact this handler processes.
`void` | `initialize(ArtifactInfo[] artifacts)` Initializes the handler with a collection of all available artifacts this handler can process.
`boolean` | `isArtifact(Class clazz)` Returns true if the target Class is a class artifact handled by this object.
`boolean` | `isArtifact(GriffonClass clazz)` Returns true if the target GriffonClass is a class artifact handled by this object.

Method Detail

### findClassFor

    public GriffonClass findClassFor(String propertyName)

  Finds an artifact by its property name.

  Examples: findClassfor("fooService") returns an artifact class that can handle FooService.

  Should `propertyName` contain any dots then the portion after the last dot will be considered only.
  Parameters:
    `propertyName` - the property representation of an artifact, e.g. 'fooService'
  Returns:
    a GriffonClass instance if there's a match, null otherwise.

### getClassFor

    public GriffonClass getClassFor(Class clazz)

  Finds an artifact if the target `clazz` is handled by this ArtifactHandler.

  Parameters:
    `clazz` - a class object, i.e, BookController
  Returns:
    a GriffonClass that can handle the target class or null if the clazz is not handled by this ArtifactHandler.

### getClassFor

    public GriffonClass getClassFor(String fqnClassName)

  Finds an artifact by class name if it represents a class that is handled by this ArtifactHandler.

  Parameters:
    `fqnClassName` - a full qualified class name, i.e, "book.BookController"
  Returns:
    a GriffonClass that can handle the target class or null if the clazz is not handled by this ArtifactHandler.

### getClasses

    public GriffonClass[] getClasses()

  Returns the set of all artifact classes this handler manages.
  Returns:
    an array of all GriffonClasses managed by this handler. Never returns null.

### getTrailing

    public String getTrailing()

  Get the trailing suffix that identifies the artifact.

  May be empty but non-null.

  Returns:
    the trailing name suffix (if any), e.g. 'Service'

### getType

    public String getType()

  Get the type of artifact this handler processes.
  Returns:
    the type of artifacts this handler can handle, e.g. 'service'

### initialize

    public void initialize(ArtifactInfo[] artifacts)

  Initializes the handler with a collection of all available artifacts this handler can process.

  This is a good time to pre-emptively instantiate beans or perform additional checks on artifacts.

  Parameters:
    `artifacts` - an array of all artifacts this handler should manage

### isArtifact

    public boolean isArtifact(Class clazz)

  Returns true if the target Class is a class artifact handled by this object.
  Parameters:
    `clazz` - a Class instance
  Returns:
    true if this handler is capable of handling the artifact class, false otherwise.

### isArtifact

    public boolean isArtifact(GriffonClass clazz)

  Returns true if the target GriffonClass is a class artifact handled by this object.
  Parameters:
    `clazz` - a GriffonClass instance
  Returns:
    true if this handler is capable of handling the clazz parameter, false otherwise.
