另外，下述各方法实施例中的步骤时序仅为一种举例，而非严格限定。
图1为本发明实施例提供的一种事件处理方法的流程图，如图1所示，该方法包括如下步骤：
101、接收对应于第一对象的第一事件注册信息。
可选地，该事件处理方法可以应用于嵌入式设备中，该嵌入式设备例如可以是传感器、智能家居设备等物联网设备，具体地，该事件处理方法可以由该嵌入式设备中的操作系统来执行。
可选地，该事件处理方法也可以应用于其他电子设备中，比如笔记本电脑、手机等。
其中，第一对象可以是某应用程序中的某个功能模块。
比如，该应用程序是一种提供对设备进行联网处理的应用程序，在该应用程序下提供了两个功能模块：本地局域网通信模块和云端通信模块。其中，本地局域网通信模块提供了通过将设备接入本地局域网而使设备联网的功能；云端通信模块提供了将设备接入远端互联外或者说公网而使识别联网的功能。
而不管是本地局域网通信模块还是云端通信模块，为实现将设备连接入网的目的，比如均需要注册“获取设备的IP地址”这个事件行为。
因此，应用程序可以针对本地局域网通信模块进行一次事件注册，针对云端通信模块也进行一次事件注册。
针对本地局域网通信模块进行事件注册时，应用程序生成事件注册信息，并将事件注册信息发送至设备的操作系统。其中，与本地局域网通信模块对应的事件注册信息中可以包括：“获取设备的IP地址”这个事件行为、本地局域网通信模块响应这个事件行为的回调函数。可选地，该事件注册信息中还可以包括本地局域网通信模块对应的优先级，即相对于注册“获取设备的IP地址”这个事件行为的其他功能模块的优先级。
同样地，针对云端通信模块进行事件注册时，应用程序生成与之对应的事件注册信息，并将事件注册信息发送至设备的操作系统。此时，与云端通信模块对应的事件注册信息中可以包括：“获取设备的IP地址”这个事件行为、云端通信模块响应这个事件行为的回调函数。可选地，该事件注册信息中还可以包括云端通信模块对应的优先级。
基于上述举例，第一对象可以是本地局域网通信模块或云端通信模块。当第一对象 为本地局域网通信模块时，与本地局域网通信模块对应的事件注册信息称为第一事件注册信息；当第一对象为云端通信模块时，与云端通信模块对应的事件注册信息称为第一事件注册信息。
102、若已分配的第一存储空间不足以容纳第一事件注册信息，则分配第二存储空间，其中，第一存储空间和第二存储空间均可容纳第一数量的事件注册信息，第一数量小于一个对象可允许注册的最大事件数量。
103、将第一事件注册信息存储到第二存储空间中。
操作系统在接收到第一事件注册信息后，需要存储该第一事件注册信息。由于诸如传感器、智能家居设备等嵌入式设备的资源受限，为了兼顾资源消耗情况，本发明实施例中采用了按需批量分配存储空间的策略。其中，存储空间用于存储事件注册信息。
具体来说，在需要进行存储空间分配时，操作系统可以一次分配足以容纳多个事件注册信息的存储空间，也就是说，操作系统以可以容纳多个事件注册信息的存储空间作为一个分配单位，进行存储空间的分配。
其中，多个事件注册信息中的多个，以第一数量来表示，实际上，会设置该第一数量大于1而小于一个对象可允许注册的最大事件数量。其中，应用程序中的一个对象可以注册的事件数量即可以具有的事件注册信息数量可能是有限定的，将该数量限定称为最大事件数量。
操作系统一次分配可以容纳第一数量的事件注册信息的存储空间，那么这个存储空间的容量是多少呢，可以根据统计每个事件注册信息所需的容量来估计。
之所以第一数量取自1和最大事件数量之间，而不取1和最大事件数量，是因为如果第一数量取为1，那么意味着每当有一个事件注册信息生成时，操作系统就需要执行一次存储空间分配动作，且此次分配的存储空间仅用于存储当前生成的一个事件注册信息。如此，当应用程序存在较多的事件注册信息时，操作系统将需要执行多次存储空间分配动作，对计算资源消耗过大。而如果第一数量取为最大事件数量(假设最大事件数量为30)，那么意味着操作系统一次需要分配能够存储30个事件注册信息的存储空间，这样虽然从整体来看，操作系统执行的存储空间分配动作数量较少，但是却存在着存储空间浪费的问题。因为如果实际上并没有那么多的事件注册信息产生，那么已经分配的存储空间将存在严重空闲的现象。
基于上述原因，第一数量取自1和最大事件数量之间。可选地，第一数量可以是经 验设定的某个数值，比如为8。可选地，还可以根据剩余存储空间的大小，和/或，根据多个对象分别对应的事件注册信息数量确定第一数量。
其中，根据剩余存储空间大小确定第一数量，是指：如果全部存储空间中未存储事件注册信息的剩余存储空间较大，则说明此时设备的存储资源不紧张，此时可以适当将第一数量设置为较大数值，比如为8；相对地，如果剩余存储空间较小，则说明此时设备的存储资源紧张，此时可以适当将第一数量设置为较小数值，比如为4。其中，上述全部存储空间是指设备中用于存储全部事件注册信息的存储空间。
其中，根据多个对象分别对应的事件注册信息数量确定第一数量，是指：可以统计应用程序中多个对象各自对应的事件注册信息数量，进而比如可以取平均值作为第一数量。
另外，操作系统一次分配足以容纳第一数量的事件注册信息的存储空间，亦可以理解为，每次分配存储空间时，假设后续可能会有第一数量个对象也需要注册当前产生的事件注册信息中的事件行为，从而按照第一数量个事件注册信息所需要的容量分配存储空间。正如前文举例的本地局域网通信模块和云端通信模块这两个对象均注册有对应于“获取设备的IP地址”这个事件行为。基于此，第一数量也可以是根据应用程序中最多会有多少个对象会注册同一事件行为而确定。而针对任一事件行为，应用程序中有多少对象需要注册这个事件行为，应用程序的设计者是可以计算出的。比如，针对事件行为A，会有3个对象需要注册，针对事件行为B，会有8个对象需要注册，则第一数量可以设置为8。
以上对操作系统的按需批量分配存储空间的策略进行了介绍。在实际应用中，何时触发操作系统进行一次存储空间的分配，是根据如下方式确定的：当操作系统接收到某个事件注册信息时，如果该事件注册信息是应用程序发送的第一个事件注册信息，那么触发操作系统进行一次存储空间的分配，即分配足以容纳第一数量的事件注册信息的存储空间。而如果该事件注册信息不是应用程序发送的第一个事件注册信息，那么可以根据之前已经分配的那个存储空间中是否已经存储了第一数量的事件注册信息来确定是否需要触发一次新的存储空间分配过程。具体地，如果之前已经分配的那个存储空间中已经存储了第一数量的事件注册信息，则触发一次新的存储空间分配过程，反正，不会触发一次新的存储空间分配过程。
综上，以操作系统接收到上述第一事件注册信息来说，若已分配的第一存储空间不 足以容纳第一事件注册信息，则分配第二存储空间。由前文所述可知，第一存储空间和第二存储空间均可容纳第一数量的事件注册信息。
其中，如果第一事件注册信息是应用程序发送的第一个事件注册信息，那么第一存储空间还不存在，则不足以容纳第一事件注册信息。而如果第一事件注册信息并非第一个事件注册信息，那么若之前分配的第一存储空间内已经存储有第一数量的事件注册信息，那么第一存储空间将不足以容纳第一事件注册信息，进行第二存储空间的分配。相反地，若第一存储空间中存储的事件注册信息的数量小于第一数量，则可以将第一事件注册信息存入到第一存储空间内即可，无需进行第二存储空间的分配。
综上，操作系统通过按需批量分配用于存储事件注册信息的存储空间，可以降低存储空间的浪费以及频繁分配存储空间导致的计算资源浪费。
图2为本发明实施例提供的另一种事件处理方法的流程图，如图2所示，可以包括如下步骤：
201、接收对应于第一对象的第一事件注册信息，第一事件注册信息中包括事件行为和第一对象的优先级。
202、若已分配的第一存储空间不足以容纳第一事件注册信息，且第一存储空间中存储有包含所述事件行为的第二事件注册信息，则分配整数倍于第一数量的第二存储空间，第二事件注册信息对应于第二对象。
203、将第一存储空间中存储的各事件注册信息复制到第二存储空间中，并释放第一存储空间。
204、根据所述事件行为以及第一对象和第二对象的优先级，按照设定的优先级排序策略，将第一事件注册信息插入到第二事件注册信息的相邻位置。
由前文所述可知，应用程序中可能会有不同的对象注册有相同的事件行为，而如果对应于同一事件行为的多个对象所各自对应的事件注册信息被较为分散地存储，那么在该事件行为被用户触发时，操作系统可能需要遍历所有的存储空间以便找到注册有该事件行为的对象。
为了降低操作系统的计算量，本实施例中，在对事件注册信息进行存储时，采用了集中存储的策略，所谓集中存储是指将注册有同一事件行为的多个事件注册信息集中存储。
具体来说，当如前述其他实施例中的说明，确定第一存储空间不足以容纳第一事件注册信息时，进一步确定第一存储空间中存储的各事件注册信息中是否包含有该第一事件注册信息中的事件行为。如果包含有该事件行为，则以第一数量为基础，分配可容纳整数倍于第一数量的事件注册信息的第二存储空间，可以理解的是，该整数倍于第一数量，是指大于1倍，比如2倍于第一数量。假设第一数量为8，那么此时需要分配可以容纳16个事件注册信息的存储空间作为第二存储空间。
在分配好第二存储空间后，可以将第一存储空间中存储的各事件注册信息(其中包括第二事件注册信息)复制到第二存储空间中，并释放第一存储空间。其中，释放第一存储空间是指将第一存储空间中存储的各事件注册信息删除。进而，可以基于上述事件行为，将与第二事件注册信息具有相同事件行为的第一事件注册信息插入到第二事件注册信息的相邻位置。
另外，在一可选实施例中，第一事件注册信息中可以包括其对应的第一对象的优先级，第二事件注册信息中也可以包括其对应的第二对象的优先级。该优先级的作用体现为：当上述事件行为被用户触发时，操作系统可以根据该优先级确定需要进行响应的对象，即确定具有高优先级的对象来响应该事件行为的发生。
基于此，操作系统在将第一事件注册信息插入到第二事件注册信息的相邻位置的过程中，可以按照设定的优先级排序策略，将第一事件注册信息插入到第二事件注册信息的相邻位置。比如，假设第一对象的优先级高于第二对象，优先级排序策略是由高到低排列，则可以将第一事件注册信息插入到第二事件注册信息的左侧相邻位置。
图3为本发明实施例提供的又一种事件处理方法的流程图，如图3所示，可以包括如下步骤：
301、接收对应于第一对象的第一事件注册信息，第一事件注册信息中包括事件行为和第一对象的优先级。
302、若第一存储空间足以容纳第一事件注册信息，且第一存储空间中存储有包含所述事件行为的第三事件注册信息，第三事件注册信息对应于第三对象，则根据所述事件行为以及第一对象和第三对象的优先级，按照设定的优先级排序策略，将第一事件注册信息插入到第三事件存储信息的相邻位置。
当然，可以理解的是，第一事件注册信息中也可以不包括第一对象的优先级，此时，操作系统仅需要将对应于同一事件行为的第一事件注册信息和第三事件注册信息相 邻存储即可。
通过以上各实施例对事件注册信息的存储过程进行了说明，但是，在实际应用中，事件除了涉及注册过程外，还会涉及到事件触发过程以及事件注销过程。下面对这两种过程分别进行说明。
在一可选实施例中，事件触发过程可以实现为如下步骤：
响应于事件行为的触发，查询包含有该事件行为的各事件注册信息；
根据各事件注册信息分别对应的对象的优先级，确定响应该事件行为的目标对象；
通知目标对象对该事件行为进行响应处理。
如前述图2或图3所示实施例中的介绍，当注册了同一事件行为的各事件注册信息被集中存储时，操作系统感应到该事件行为被触发时，可以在各存储空间中查找注册了该事件行为的各事件注册信息。如果在某存储空间中找到了一个注册了该事件行为的事件注册信息，那么其他的注册了该事件行为的事件注册信息也便找到了。此时，操作系统可以根据各事件注册信息分别对应的对象的优先级，确定响应该事件行为的目标对象。可以理解的是，当上述各事件注册信息是按照各自对应的对象的优先级进行集中存储的时，操作系统可以基于优先级排序策略方便地定位到目标对象。
操作系统通知目标对象对该事件行为进行响应处理，可以是操作系统直接将该目标对象对应的事件注册信息中的回调函数提供给目标对象，目标对象执行该回调函数以对该事件行为进行响应。
另外，可选地，操作系统通知目标对象对上述事件行为进行响应处理，还可以实现为：操作系统将目标对象对应的回调函数发送至某队列中，以使该队列通知目标对象从队列中读取该回调函数以对上述事件行为进行响应处理。通过这种方式，其实是实现了操作系统与上层的应用程序之间的隔离，即使应用程序层面的目标对象的响应过程出现异常，也不至于影响操作系统的正常运行。
在一可选实施例中，以前述第一事件注册信息为例，事件注销过程可以实现为如下步骤：
响应于第一事件注册信息的注销，从第二存储空间中删除第一事件注册信息；
若第一存储空间和第二存储空间中的空闲存储空间达到能够容纳第二数量的事件注册信息，则回收空闲存储空间，其中，第二数量多于第一数量。
由此可知，在事件注销的过程中，可能会涉及到存储空间的回收处理。
假设基于前文的存储过程的描述，第一事件注册信息被存入到第二存储空间中，并且假设目前总共已经分配的存储空间由第一存储空间和第二存储空间构成，那么在第一事件注册信息被注销时，操作系统需要删除存储在第二存储空间中的该第一事件注册信息。
在删除了第一事件注册信息后，操作系统还可以进一步确定当前已分配的存储空间即第一存储空间和第二存储空间中的空闲情况，如果空闲情况符合设定的阈值条件，则可以对其中的空闲存储空间进行回收。
具体地，若第一存储空间和第二存储空间中的空闲存储空间达到能够容纳第二数量的事件注册信息，则回收空闲存储空间，其中，第二数量多于第一数量。举例来说，假设第一数量为8，第二数量为12，这就意味着理论上第一存储空间和第二存储空间一共可以容纳16个事件注册信息。如果发现第一存储空间和第二存储空间中一共存储的事件注册信息的数量已经由较多数量下降到4，说明第一存储空间和第二存储空间中已经出现了12个事件注册信息的空闲存储空间，此时需要回收这些空闲存储空间。
可选地，操作系统可以全部回收这些空闲存储空间。
但是，为了避免在某事件注册信息刚被注销后随后又被重新注册的情况下，需要重新分配一次存储空间而导致的计算量开销，操作系统也可以仅回收这些空闲存储空间中的部分空闲存储空间。
具体地，操作系统可以从这些空闲存储空间中回收整数倍于第一数量的部分，其中，第二数量大于第一数量的该整数倍。由于存储空间的分配是以第一数量为单位的，因此，回收空闲存储空间时也可以以第一数量的整数倍为基准来回收，该整数倍可以是1倍或多倍。
当然，可选地，操作系统也可以根据按照一定的比例对这些空闲存储空间进行部分回收，比如设定的比例为70％，那么结合前述的举例，如果空闲存储空间已经达到可以容纳12个事件注册信息的容量，那么操作系统可以回收其中向下取整12*70％的结果所对应的存储空间，向下取整12*70％的结果为8，即回收可以容纳8个事件注册信息的存储空间。
以下将详细描述本发明的一个或多个实施例的事件处理装置。本领域技术人员可以理解，这些事件处理装置均可使用市售的硬件组件通过本方案所教导的步骤进行配置来 构成。
