Obscure Syntax

[tw2035]

HI,

I have had a 5 year Java holiday from C++ and seem to have become super
rusty.
Can anyone tell me what this syntax below means (inside "THIS CODE
HERE" comment):

......
......
#include <iostream>
#include <cmath>

using namespace std;

// THIS CODE HERE --->
StaticSynapse::NeuronConnector StaticSynapse::Connect;
DynamicSynapse::NeuronConnector DynamicSynapse::Connect;
// <----------------------------------


Synapse::Synapse(SynapseProperties& synProps):
dendrite(0),
lastTransTime(0)
{
....
....

I dont mean what it does in this context but what is it? A Forward
declaration or something? It seems to have the form "ClassA ClassB;"

I would really appreciate any tips.
Cheers

// THIS CODE HERE --->
StaticSynapse::NeuronConnector StaticSynapse::Connect;
DynamicSynapse::NeuronConnector DynamicSynapse::Connect;
// <----------------------------------

Looks like:

"StaticSynapse" is a class
"NeuronConnector" is a type which is defined within the class.
"Connect" is a static member.


It looks like this is the definition of the static member objects.


class Synapse
{
typedef int NeuronConnector;
};

class StaticSynapse : public Synapse
{
static NeuronConnector Connect; //static member data declaration
};

class DynamicSynapse : public Synapse
{
static NeuronConnector Connect; //static member data declaration

};


//Here's where the objects are actually defined
StaticSynapse::NeuronConnector StaticSynapse::Connect;
DynamicSynapse::NeuronConnector DynamicSynapse::Connect;

Thanks a lot.
I was thrown by the capitalisation. I thought it was:
NAMESPACEA::CLASSA NAMESPACEA::CLASSB;
NAMESPACEB::CLASSC NAMESPACEB::CLASSC;

But I see now.
