具体实现源码没研究，写了几行测试代码，发现和stl的vector差不多，会自动扩容，支持随机存取。

从测试结果来看，自动扩容的机制也和vector一样，如下：

		m_array=wyArrayNew(4);
		wyArrayPush(m_array,new wyObject());
		wyArrayPush(m_array,new wyObject());
		wyArrayPush(m_array,new wyObject());
		wyArrayPush(m_array,new wyObject());

	LOGD("==== length :  %d =====",adapter->getLength());
	LOGD("==== size :  %d =====",adapter->getSize());
	wyArrayPush(m_array,new wyObject());
	LOGD("==== length :  %d =====",adapter->getLength());
	LOGD("==== size :  %d =====",adapter->getSize());

输出结果依次是

4,4    

5,8
