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`)

### isMaterialized

    public boolean isMaterialized()

### 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`)

### 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, with `Integer.MAX_VALUE` indicating the greatest value. Same order values will result in arbitrary positions for the affected objects.

  Higher values can be interpreted as lower priority. As a consequence, the object with the lowest value has highest priority (somewhat analogous to Servlet "load-on-startup" values).

  Specified by:
    `getOrder` in interface `Ordered`
  Returns:
    the order value

### toString

    public java.lang.String toString()

  Overrides:
    `toString` in class `java.lang.Object`
