Method Detail

getManagedAnnotation

public I18N getManagedAnnotation(AnnotatedElement element)

When overridden in an injector class, retrieves the annotation processed by this particular injector. Takes into account that there might be several annotations attached to the current Java class member, and an injector can potentially process several annotation types, depending on the setup

Parameters:

element - AnnotatedElement instance that facades the Java class member and allows retrieving annotations

Returns:

Annotation instance

getName

@Nonnull
public String getName()

Retrieves the name of the current instance

Returns:

String value

getValue

@Nonnull
public Injectable getValue(Object adaptable,
                                     String name,
                                     Type type,
                                     I18N annotation)

When overridden in an injector class, extracts a value from a SlingHttpServletRequest or a Resource instance

Parameters:

adaptable - A SlingHttpServletRequest or a Resource instance

name - Name of the Java class member to inject the value into

type - Type of the receiving Java class member

annotation - Annotation handled by the current injector

Returns:

A non-null Injectable instance that contains the payload that can be null

                                            org.apache.sling.models.spi.DisposalCallbackRegistry callbackRegistry)

Attempts to produce a value that can be further injected by Sling into the given adaptable

Specified by:

getValue in interface org.apache.sling.models.spi.Injector

Parameters:

adaptable - A SlingHttpServletRequest or a Resource instance

name - Name of the Java class member to inject the value into

type - Type of receiving Java class member

element - AnnotatedElement instance that facades the Java class member and allows to retrieve annotations

callbackRegistry - DisposalCallbackRegistry object

Returns:

A nullable value
