类 HotSwappableTargetSource

构造器详细资料

• HotSwappableTargetSource

  public HotSwappableTargetSource​(Object initialTarget)

  Create a new HotSwappableTargetSource with the given initial target object.

  参数:

  initialTarget - the initial target object

方法详细资料

• getTargetClass

  public Class<?> getTargetClass()

  Return the type of the current target object.

  The returned type should usually be constant across all target objects.

  指定者:

  getTargetClass 在接口中 TargetClassAware

  指定者:

  getTargetClass 在接口中 TargetSource

  返回:

  the type of targets returned by this TargetSource

• isStatic

  public final boolean isStatic()

  从接口复制的说明: TargetSource
  Will all calls to TargetSource.getTarget() return the same object?

  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().

  指定者:

  isStatic 在接口中 TargetSource

  返回:

  true if the target is immutable

  另请参阅:

  TargetSource.getTarget()

• getTarget

  public Object getTarget()

  从接口复制的说明: TargetSource
  Return a target instance. Invoked immediately before the AOP framework calls the "target" of an AOP method invocation.

  指定者:

  getTarget 在接口中 TargetSource

  返回:

  the target object which contains the joinpoint, or null if there is no actual target instance

• releaseTarget

  public void releaseTarget​(Object target)

  从接口复制的说明: TargetSource
  Release the given target object obtained from the TargetSource.getTarget() method, if any.

  指定者:

  releaseTarget 在接口中 TargetSource

  参数:

  target - object obtained from a call to TargetSource.getTarget()

• swap

  public Object swap​(Object newTarget)
              throws IllegalArgumentException

  Swap the target, returning the old target object.

  参数:

  newTarget - the new target object

  返回:

  the old target object

  抛出:

  IllegalArgumentException - if the new target is invalid

• equals

  public boolean equals​(Object other)

  Two HotSwappableTargetSources are equal if the current target objects are equal.

  覆盖:

  equals 在类中 Object

• hashCode

  public int hashCode()

  覆盖:

  hashCode 在类中 Object

• toString

  public String toString()

  覆盖:

  toString 在类中 Object
