Constructor Description
SingletonAspectInstanceFactory(Object aspectInstance)
Create a new SingletonAspectInstanceFactory for the given aspect instance.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`ClassLoader`	`getAspectClassLoader()`	Expose the aspect class loader that this factory uses.
`Object`	`getAspectInstance()`	Create an instance of this factory's aspect.
`int`	`getOrder()`	Determine the order for this factory's aspect instance, either an instance-specific order expressed through implementing the `Ordered` interface, or a fallback order.
`protected int`	`getOrderForAspectClass(Class<?> aspectClass)`	Determine a fallback order for the case that the aspect instance does not express an instance-specific order through implementing the `Ordered` interface.

```
public SingletonAspectInstanceFactory(Object aspectInstance)
```
    Create a new SingletonAspectInstanceFactory for the given aspect instance.
    Parameters:
    aspectInstance - the singleton aspect instance
- Method Detail
  - getAspectInstance
```
public final 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 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)
  - getOrder
```
public int getOrder()
```
    Determine the order for this factory's aspect instance, either an instance-specific order expressed through implementing the Ordered interface, or a fallback order.
    Specified by:
    getOrder in interface Ordered
    Returns:
    the order value
    See Also:
    Ordered, getOrderForAspectClass(java.lang.Class<?>)
  - getOrderForAspectClass
```
protected int getOrderForAspectClass(Class<?> aspectClass)
```
    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.
    Parameters:
    aspectClass - the aspect class
