任何方式缓存从谷歌云终端查询结果? [英] Any way to cache query results from google cloud endpoints?
问题描述
我需要存储在本地我解雇了最后一次客户端Android应用程序,可以立即使用数据的查询结果。
更新后的数据可以稍后从AsyncTack或线程
这是生成的客户端库返回的对象是扩展GenericJson类
有没有办法将它转换成共享preferences一个String和商店,后来又实例化对象?

}
我通过实现一个惊人的库解决了这个问题。
使用上述样本库code:
公共类MainListingsUpdate扩展的AsyncTask<太虚,太虚,太虚> { 私人CollectionResponseMainEventListing名单=新CollectionResponseMainEventListing();
私人DualCache< CollectionResponseMainEventListing>高速缓存; @覆盖
保护无效doInBackground(虚空......空隙){
尝试{
。名单= mainActivityConnect.getAppUserApi()getMainListings()执行(); 一下SizeOf< CollectionResponseMainEventListing>整型尺寸=新中SizeOf< CollectionResponseMainEventListing>(){
@覆盖
公众诠释整型尺寸(CollectionResponseMainEventListing对象){
返回object.toString()的getBytes()长度。
}
}; 缓存=新DualCacheBuilder<>(Constants.cacheName,1,CollectionResponseMainEventListing.class)
.useReferenceInRam(Integer.MAX_VALUE的,整型尺寸)
.useDefaultSerializerInDisk(Integer.MAX_VALUE的,真正的); cache.put(OBJECT_KEY清单); }赶上(IOException异常五){
queryComplete = FALSE;
}
返回null;
} }
和检索,它的那样简单:
cache.get(OBJECT_KEY);
I need to store the results of the query that i fired the last time locally on the client android app for immediately using the data. The updated data can be fetched later from an AsyncTack or a thread
The objects that the generated client libraries return are of class that extends GenericJson
is there any way to convert this into a String and store in sharedpreferences and Later instantiate the Objects again ?
heres the class definition

package sanket.pinboard.backend.postApi.model;
public final class Post extends com.google.api.client.json.GenericJson {

public sanket.pinboard.backend.postApi.model.Post clone() { /* compiled code */ }
}
I solved the problem by implementing an amazing library
sample code using the above library :
public class MainListingsUpdate extends AsyncTask<Void, Void, Void> {
private CollectionResponseMainEventListing list = new CollectionResponseMainEventListing();
private DualCache<CollectionResponseMainEventListing> cache;
@Override
protected Void doInBackground(Void... voids) {
try {
list = mainActivityConnect.getAppUserApi().getMainListings().execute();
SizeOf<CollectionResponseMainEventListing> sizeOf = new SizeOf<CollectionResponseMainEventListing>() {
@Override
public int sizeOf(CollectionResponseMainEventListing object) {
return object.toString().getBytes().length;
}
};
cache = new DualCacheBuilder<>(Constants.cacheName, 1, CollectionResponseMainEventListing.class)
.useReferenceInRam(Integer.MAX_VALUE, sizeOf)
.useDefaultSerializerInDisk(Integer.MAX_VALUE, true);
cache.put("OBJECT_KEY", list);
} catch (IOException e) {
queryComplete = false;
}
return null;
}
}
and to retrieve , its as simple as :
cache.get("OBJECT_KEY");
