java.lang.Objectorg.springframework.aop.target.SingletonTargetSource
public class SingletonTargetSource
Implementation of the 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(Object target)
Create a new SingletonTargetSource for the given target. |
Method Summary | |
---|---|
boolean |
equals(Object other)
Two invoker interceptors are equal if they have the same target or if the targets or the targets are equal. |
Object |
getTarget()
Return a target instance. |
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(Object target)

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()
.
