gpg::ICrossAppEndpointDiscoveryListener
这是一个抽象类。
#include <i_cross_app_endpoint_discovery_listener.h>
定义一个接口，用于传送与跨应用远程端点发现相关的事件。
摘要
公共函数
OnCrossAppEndpointFound
virtual void OnCrossAppEndpointFound(
int64_t client_id,
const EndpointDetails & endpoint_details,
const std::vector< AppIdentifier > & app_identifiers
)=0
在找到远程端点时调用；对于每个发现的端点，都会调用一次。
请注意，此方法可能会在短时间内反复调用；您可能需要延迟对界面的更新，以便在调用此方法后的一小段时间内反映新端点。
OnCrossAppEndpointLost
virtual void OnCrossAppEndpointLost(
int64_t client_id,
const std::string & instance_id
)=0
在远程端点无法再被发现时调用；仅使用之前传递给 OnEndpointFound 的 ID 调用。
请注意，此方法可能会在短时间内反复调用；您可能需要延迟对界面的更新，以反映在调用此方法后端点消失了一小段时间。
