In the world of financial applications, performance and memory management are crucial. Pool allocation of objects can greatly increase efficiency by reusing memory, reducing the overhead of frequent allocations and deallocations. Here’s how to implement object pooling in C++ for financial applications.
#include <iostream>
#include <vector>
#include <memory>
class FinancialData {
public:
FinancialData() { /* Initialization logic */ }
void process() { /* Processing logic for financial data */ }
};
class ObjectPool {
public:
ObjectPool(size_t size) {
for (size_t i = 0; i < size; ++i) {
pool.emplace_back(std::make_unique<FinancialData>());
}
}
std::unique_ptr<FinancialData> acquireObject() {
if (!pool.empty()) {
auto object = std::move(pool.back());
pool.pop_back();
return object;
}
return nullptr;
}
void releaseObject(std::unique_ptr<FinancialData> object) {
pool.push_back(std::move(object));
}
private:
std::vector<std::unique_ptr<FinancialData>> pool;
};
int main() {
ObjectPool pool(10); // Creates a pool of 10 FinancialData objects
auto obj = pool.acquireObject();
if (obj) {
obj->process(); // Process financial data
pool.releaseObject(std::move(obj)); // Release object back to pool
}
return 0;
}
