Heapbuffer directbuffer
Web#directBuffer(int) allocates a new fixed-capacity direct buffer. #dynamicBuffer(int) allocates a new dynamic-capacity heap buffer, whose capacity increases automatically as needed by a write operation. Creating a wrapped buffer Wrapped buffer is a buffer which is a view of one or more existing byte arrays and byte buffers.

两个都是Buffer ,不同的是前者使用的是堆外内存，后者时候的是 JVM 堆内内存。在使用 FileChannel 读写的时候内部实现就有点不同了。以下是FileChannel使用代码 如果上面的代码channel.write传入的参数是HeapBuffer类型,则会临时申请一块DirectBuffer,将HeapBuffer中的数据进行数据拷贝到堆外内存，然 … Ver más DirectByteBuffer 自身是一个Java对象，在Java堆中；而这个对象中有个long类型字段address，记录着一块调用 malloc() 申请到的native memory … Ver más 关于 Heap memory 和 Native memory的解释，来自stackoverflow 1.
