BindService流程中的数据类

IntentBindRecord: 记录了ProcessRecord对应的所有的bind信息

// A particular Intent that has been bound to a Service.
final class IntentBindRecord {
    /** The running service. */
    final ServiceRecord service;
    /** The intent that is bound.*/
    final Intent.FilterComparison intent; // 
    /** All apps that have bound to this Intent. */
    // 用户进程对应的所有的bind集合
    final ArrayMap<ProcessRecord, AppBindRecord> apps
            = new ArrayMap<ProcessRecord, AppBindRecord>();
    /** Binder published from service. */
    IBinder binder;
    /** Set when we have initiated a request for this binder. */
    boolean requested;
    /** Set when we have received the requested binder. */
    boolean received;
    /** Set when we still need to tell the service all clients are unbound. */
    boolean hasBound;
    /** Set when the service's onUnbind() has asked to be told about new clients. */
    boolean doRebind;
    
    String stringName;      // caching of toString

    IntentBindRecord(ServiceRecord _service, Intent.FilterComparison _intent) {
        service = _service;
        intent = _intent;
    }
}

AppBindRecord： ServiceRecord对应的一个app端的conn集合

// An association between a service and one of its client applications.
final class AppBindRecord {
    final ServiceRecord service;    // The running service.
    final IntentBindRecord intent;  // The intent we are bound to.
    final ProcessRecord client;     // Who has started/bound the service.
    //
    final ArraySet<ConnectionRecord> connections = new ArraySet<>();
                                    // All ConnectionRecord for this client.

    AppBindRecord(ServiceRecord _service, IntentBindRecord _intent,
            ProcessRecord _client) {
        service = _service;
        intent = _intent;
        client = _client;
    }
}

ConnectionRecord: 单个bind信息的描述

// Description of a single binding to a service.
final class ConnectionRecord {
    final AppBindRecord binding;    // The application/service binding.
    final ActivityRecord activity;  // If non-null, the owning activity.
    final IServiceConnection conn;  // The client connection.
    final int flags;                // Binding options.
    final int clientLabel;          // String resource labeling this client.
    final PendingIntent clientIntent; // How to launch the client.
    String stringName;              // Caching of toString.
    boolean serviceDead;            // Well is it?

    ConnectionRecord(AppBindRecord _binding, ActivityRecord _activity,
               IServiceConnection _conn, int _flags,
               int _clientLabel, PendingIntent _clientIntent) {
        binding = _binding;
        activity = _activity;
        conn = _conn;
        flags = _flags;
        clientLabel = _clientLabel;
        clientIntent = _clientIntent;
    }
}
