how to new some class from template

[Jianli Shen]

template is this:

template <class Data>
class FastQueue{

public:
FastQueue(int size){ }
}

I declare myQueue;
FastQueue<DInst *> myQueue;
I don't want to initialize it in constructor use myQueue(32)

I need use new to initialize it:

trie:
myQueue = new FastQueue<DInst *>::FastQueue(32)

failed, don't know how to do

Thanks for help!

error get is :
no matching function
for call to `FastQueue<DInst*>::FastQueue()'
...../FastQueue.h:52: candidates are:
FastQueue<DInst*>::FastQueue(const FastQueue<DInst*>&)
...../FastQueue.h:63:
FastQueue<Data>::FastQueue(unsigned int) [with Data = DInst*]

Drop the '::' and the "constructor name". Do

FastQueue<DInst*> *myQueue = new FastQueue<DInst*>(32);

First of all your variable has to be a pointer, and second, you the 'new'
expression needs a type, not a "constructor name".
