AbstractArtifactHandler

@Inject
public AbstractArtifactHandler(@Nonnull
                              GriffonApplication application,
                              @Nonnull
                              Class<A> artifactType,
                              @Nonnull
                              String type,
                              @Nonnull
                              String trailing)

Method Detail

getArtifactType

@Nonnull
public Class<A> getArtifactType()

Specified by:

getArtifactType in interface ArtifactHandler<A extends GriffonArtifact>

getType

@Nonnull
public String getType()

Description copied from interface: ArtifactHandler

Get the type of artifact this handler processes.

Specified by:

getType in interface ArtifactHandler<A extends GriffonArtifact>

Returns:

the type of artifacts this handler can handle, e.g. 'service'

getTrailing

@Nonnull
public String getTrailing()

Description copied from interface: ArtifactHandler

Get the trailing suffix that identifies the artifact.

May be empty but non-null.

Specified by:

getTrailing in interface ArtifactHandler<A extends GriffonArtifact>

Returns:

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

initialize

@Nonnull
public Collection<Binding<?>> initialize(@Nonnull
                                        Class<A>[] classes)

Description copied from interface: ArtifactHandler

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

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

Specified by:

initialize in interface ArtifactHandler<A extends GriffonArtifact>

Parameters:

classes - an array of all classes this handler should manage

createBindings

protected void createBindings(@Nonnull
                  List<Binding<?>> bindings,
                  @Nonnull
                  Class<A> clazz,
                  @Nonnull
                  GriffonClass griffonClass)

getClassesByName

@Nonnull
public Map<String,GriffonClass> getClassesByName()

Specified by:

getClassesByName in interface ArtifactHandler<A extends GriffonArtifact>

isArtifact

public boolean isArtifact(@Nonnull
                 Class<A> clazz)

Returns true if the target Class is a class artifact handled by this object.

This implementation performs an equality check on class.name

Specified by:

isArtifact in interface ArtifactHandler<A extends GriffonArtifact>

Parameters:

clazz - a Class instance

Returns:

true if this handler is capable of handling the artifact class, false otherwise.

isArtifact

public boolean isArtifact(@Nonnull
                 GriffonClass clazz)

Description copied from interface: ArtifactHandler

Returns true if the target GriffonClass is a class artifact handled by this object.

Specified by:

isArtifact in interface ArtifactHandler<A extends GriffonArtifact>

Parameters:

clazz - a GriffonClass instance

Returns:

true if this handler is capable of handling the clazz parameter, false otherwise.

getClasses

@Nonnull
public GriffonClass[] getClasses()

Description copied from interface: ArtifactHandler

Returns the set of all artifact classes this handler manages.

Specified by:

getClasses in interface ArtifactHandler<A extends GriffonArtifact>

Returns:

an array of all GriffonClasses managed by this handler. Never returns null.

getClassFor

@Nullable
public GriffonClass getClassFor(@Nonnull
                                Class<A> clazz)

Description copied from interface: ArtifactHandler

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

Specified by:

getClassFor in interface ArtifactHandler<A extends GriffonArtifact>

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

@Nullable
public GriffonClass getClassFor(@Nonnull
                                String fqnClassName)

Description copied from interface: ArtifactHandler

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

Specified by:

getClassFor in interface ArtifactHandler<A extends GriffonArtifact>

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.

findClassFor

@Nullable
public GriffonClass findClassFor(@Nonnull
                                 String propertyName)

Description copied from interface: ArtifactHandler

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.

Specified by:

findClassFor in interface ArtifactHandler<A extends GriffonArtifact>

Parameters:

propertyName - the property representation of an artifact, e.g. 'fooService'

Returns:

a GriffonClass instance if there's a match, null otherwise.

getApplication

@Nonnull
protected GriffonApplication getApplication()
