Checks if an object implements an interface.
Example:



 var util =  require('./util');
 util.checkInterface(myPublisher, interfaces.IPublisher);

             		                            
util.checkInterface = function(theObject, theInterface, options) {
    options = options || {};    
    var silent = options.silent || false;
    
    for (var member in theInterface) {
        if ( (typeof theObject[member] != typeof theInterface[member]) ) {
            if (!silent) {
                console.log('object failed to implement interface member ' + member);
                console.log(member + ' expected: \'' + typeof theInterface[member] + '\' but was: \'' + typeof theObject[member] + '\'')
            }
            return false;
        }
    }
             		           
                               
                            
                                
               
If we get here, it passed the test, so return true.
             		                            
    return true;
};
