The RJCB-generated bridge code makes direct, interface-specific vtable calls.
RJCB 生成的桥代码可以进行直接的、针对特定接口的 vtable调用。
The RJCB code generator generates Java proxies for each vtable interface and coclass defined in the COM type library.
RJCB代码生成器为COM类型库中定义的每个vtable接口和 辅助类生成代理。
The performance of this sample and the pure vtable-based sample are exactly identical.
这个例子的性能和纯虚函数表例子是相同的。
The memory image of an instance of a class has one pointer to the vtable of this class, stored in front of the actual data members of the object.
类的实例的内存快照里有一个vtable的指针，该指针位置在实际的成员变量前面。
Overhead in memory is very small: You basically have a 4- byte overhead per interface (the vtable pointers in the object's instance data) plus 4 bytes for the reference counter.
内存开销非常小：基本上每个接口需要额外4个字节（对象实例数据里虚函数表指针），加上引用计数的4个字节。
