Constructor Detail

LazySingletonAspectInstanceFactoryDecorator

public LazySingletonAspectInstanceFactoryDecorator(MetadataAwareAspectInstanceFactory maaif)
Create a new lazily initializing decorator for the given AspectInstanceFactory.

Parameters:
maaif - the MetadataAwareAspectInstanceFactory to decorate
Method Detail

getAspectInstance

public java.lang.Object getAspectInstance()
Description copied from interface: AspectInstanceFactory
Create an instance of this factory's aspect.

Specified by:
getAspectInstance in interface AspectInstanceFactory
Returns:
the aspect instance (never null)

getAspectClassLoader

public java.lang.ClassLoader getAspectClassLoader()
Description copied from interface: AspectInstanceFactory
Expose the aspect class loader that this factory uses.

Specified by:
getAspectClassLoader in interface AspectInstanceFactory
Returns:
the aspect class loader (never null)

isMaterialized

public boolean isMaterialized()

getAspectMetadata

public AspectMetadata getAspectMetadata()
Description copied from interface: MetadataAwareAspectInstanceFactory
Return the AspectJ AspectMetadata for this factory's aspect.

Specified by:
getAspectMetadata in interface MetadataAwareAspectInstanceFactory
Returns:
the aspect metadata

getOrder

public int getOrder()
Description copied from interface: Ordered
Return the order value of this object, with a higher value meaning greater in terms of sorting.

Normally starting with 0 or 1, with Ordered.LOWEST_PRECEDENCE indicating greatest. Same order values will result in arbitrary positions for the affected objects.

Higher value can be interpreted as lower priority, consequently the first object has highest priority (somewhat analogous to Servlet "load-on-startup" values).

Note that order values below 0 are reserved for framework purposes. Application-specified values should always be 0 or greater, with only framework components (internal or third-party) supposed to use lower values.

Specified by:
getOrder in interface Ordered
Returns:
the order value
See Also:
Ordered.LOWEST_PRECEDENCE

toString

public java.lang.String toString()
Overrides:
toString in class java.lang.Object
