in.get(buffer,0,10);//该方法是从in(即IoBuffer)中取从0到10(不含第10个字节),共10个字节的值赋给buffer数组。 1. java.nio.ByteBuffer的API中mark、position、limit、flip、reset几个方法非常重要,下面的例子结合源码可以帮助大家更好地掌握: String str = "helloWorld"; ByteBuffer buff = ByteBuffer...
DirectByteBuffer不是分配在堆上的,它不被GC直接管理(但Direct Buffer的JAVA对象是归GC管理的,只要GC回收了它的JAVA对象,操作系统才会释放Direct Buffer所申请的空间),它似乎给人感觉是“内核缓冲区(buffer in kernel)”。HeapByteBuffer则是分配在堆上的,或者我们可以简单理解为Heap Buffer就是byte[]数组的一种封装...
