类 JsonStreamParser

java.lang.Object

com.google.gson.JsonStreamParser

所有已实现的接口:

Iterator<JsonElement>

public final class JsonStreamParser
extends Object
implements Iterator<JsonElement>

A streaming parser that allows reading of multiple JsonElements from the specified reader asynchronously.

This class is conditionally thread-safe (see Item 70, Effective Java second edition). To properly use this class across multiple threads, you will need to add some external synchronization. For example:

 JsonStreamParser parser = new JsonStreamParser("['first'] {'second':10} 'third'");
 JsonElement element;
 synchronized (parser) {  // synchronize on an object shared by threads
   if (parser.hasNext()) {
     element = parser.next();
   }
 }
 

从以下版本开始:

1.4
