示例1: list
// static
Status PlanCacheListQueryShapes::list(const PlanCache& planCache, BSONObjBuilder* bob) {
invariant(bob);
// Fetch all cached solutions from plan cache.
vector<PlanCacheEntry*> solutions = planCache.getAllEntries();
BSONArrayBuilder arrayBuilder(bob->subarrayStart("shapes"));
for (vector<PlanCacheEntry*>::const_iterator i = solutions.begin(); i != solutions.end(); i++) {
PlanCacheEntry* entry = *i;
invariant(entry);
BSONObjBuilder shapeBuilder(arrayBuilder.subobjStart());
shapeBuilder.append("query", entry->query);
shapeBuilder.append("sort", entry->sort);
shapeBuilder.append("projection", entry->projection);
shapeBuilder.doneFast();
// Release resources for cached solution after extracting query shape.
delete entry;
}
arrayBuilder.doneFast();
return Status::OK();
