ListenerInfo

public ListenerInfo(Bundle bundle,
                    BundleContext context,
                    java.lang.Class listenerClass,
                    java.util.EventListener listener,
                    Filter filter,
                    java.lang.Object acc,
                    boolean removed)

ListenerInfo

public ListenerInfo(ListenerInfo info,
                    boolean removed)

方法详细资料

getBundle

public Bundle getBundle()

getBundleContext

public BundleContext getBundleContext()

从接口复制的说明: ListenerHook.ListenerInfo

Return the context of the bundle which added the listener.

指定者:

getBundleContext 在接口中 ListenerHook.ListenerInfo

返回:

The context of the bundle which added the listener.

getListenerClass

public java.lang.Class getListenerClass()

getListener

public java.util.EventListener getListener()

getParsedFilter

public Filter getParsedFilter()

getFilter

public java.lang.String getFilter()

从接口复制的说明: ListenerHook.ListenerInfo

Return the filter string with which the listener was added.

指定者:

getFilter 在接口中 ListenerHook.ListenerInfo

返回:

The filter string with which the listener was added. This may be null if the listener was added without a filter.

getSecurityContext

public java.lang.Object getSecurityContext()

isRemoved

public boolean isRemoved()

从接口复制的说明: ListenerHook.ListenerInfo

Return the state of the listener for this addition and removal life cycle. Initially this method will return false indicating the listener has been added but has not been removed. After the listener has been removed, this method must always return true.

There is an extremely rare case in which removed notification to ListenerHooks can be made before added notification if two threads are racing to add and remove the same service listener. Because ListenerHooks are called synchronously during service listener addition and removal, the Framework cannot guarantee in-order delivery of added and removed notification for a given service listener. This method can be used to detect this rare occurrence.

指定者:

isRemoved 在接口中 ListenerHook.ListenerInfo

返回:

false if the listener has not been been removed, true otherwise.

equals

public boolean equals(java.lang.Object obj)

从接口复制的说明: ListenerHook.ListenerInfo

Compares this ListenerInfo to another ListenerInfo. Two ListenerInfos are equals if they refer to the same listener for a given addition and removal life cycle. If the same listener is added again, it must have a different ListenerInfo which is not equal to this ListenerInfo.

指定者:

equals 在接口中 ListenerHook.ListenerInfo

覆盖:

equals 在类中 java.lang.Object

参数:

obj - The object to compare against this ListenerInfo.

返回:

true if the other object is a ListenerInfo object and both objects refer to the same listener for a given addition and removal life cycle.

hashCode

public int hashCode()

从接口复制的说明: ListenerHook.ListenerInfo

Returns the hash code for this ListenerInfo.

指定者:

hashCode 在接口中 ListenerHook.ListenerInfo

覆盖:

hashCode 在类中 java.lang.Object

返回:

The hash code of this ListenerInfo.
