SingletonMetadataAwareAspectInstanceFactory

public SingletonMetadataAwareAspectInstanceFactory(Object aspectInstance,
 String aspectName)

Create a new SingletonMetadataAwareAspectInstanceFactory for the given aspect.

参数:

aspectInstance - the singleton aspect instance

aspectName - the name of the aspect

方法详细资料

getAspectMetadata

public final AspectMetadata getAspectMetadata()

从接口复制的说明: MetadataAwareAspectInstanceFactory

Return the AspectJ AspectMetadata for this factory's aspect.

指定者:

getAspectMetadata 在接口中 MetadataAwareAspectInstanceFactory

返回:

the aspect metadata

getAspectCreationMutex

public Object getAspectCreationMutex()

从接口复制的说明: MetadataAwareAspectInstanceFactory

Return the best possible creation mutex for this factory.

指定者:

getAspectCreationMutex 在接口中 MetadataAwareAspectInstanceFactory

返回:

the mutex object (may be null for no mutex to use)

getOrderForAspectClass

protected int getOrderForAspectClass(Class<?> aspectClass)

从类复制的说明: SingletonAspectInstanceFactory

Determine a fallback order for the case that the aspect instance does not express an instance-specific order through implementing the Ordered interface.

The default implementation simply returns Ordered.LOWEST_PRECEDENCE.

覆盖:

getOrderForAspectClass 在类中 SingletonAspectInstanceFactory

参数:

aspectClass - the aspect class
