public class SingletonTargetSource extends java.lang.Object implements TargetSource, java.io.Serializable
TargetSource interface
that holds a given object. This is the default implementation of the TargetSource
interface, as used by the Spring AOP framework. There is usually no need to
create objects of this class in application code.
This class is serializable. However, the actual serializability of a SingletonTargetSource will depend on whether the target is serializable.

SingletonTargetSource(java.lang.Object target)
Create a new SingletonTargetSource for the given target.

| Modifier and Type | Method and Description |
|---|---|
boolean |
equals(java.lang.Object other)
Two invoker interceptors are equal if they have the same target or if the
targets or the targets are equal.
|
java.lang.Object |
getTarget()
Return a target instance.
|
java.lang.Class<?> |
getTargetClass()
Return the type of targets returned by this
TargetSource. |
int |
hashCode()
SingletonTargetSource uses the hash code of the target object.
|
boolean |
isStatic()
Will all calls to
TargetSource.getTarget() return the same object? |
void |
releaseTarget(java.lang.Object target)
Release the given target object obtained from the
TargetSource.getTarget() method, if any. |

Can return null, although certain usages of a TargetSource
might just work with a predetermined target class.

In that case, there will be no need to invoke TargetSource.releaseTarget(Object),
and the AOP framework can cache the return value of TargetSource.getTarget().
