# Generator strategies ProxyManager allows you to generate classes based on generator strategies and a given `Laminas\Code\Generator\ClassGenerator` as of the [interface of a generator strategy](https://github.com/Ocramius/ProxyManager/blob/master/src/ProxyManager/GeneratorStrategy/GeneratorStrategyInterface.php). Currently, 3 generator strategies are shipped with ProxyManager: * [`ProxyManager\GeneratorStrategy\BaseGeneratorStrategy`](https://github.com/Ocramius/ProxyManager/blob/master/src/ProxyManager/GeneratorStrategy/BaseGeneratorStrategy.php) which retrieves the string representation of the class from `ClassGenerator` * [`ProxyManager\GeneratorStrategy\EvaluatingGeneratorStrategy`](https://github.com/Ocramius/ProxyManager/blob/master/src/ProxyManager/GeneratorStrategy/EvaluatingGeneratorStrategy.php) which calls `eval()` upon the generated class code before returning it. This is useful in cases where you want to generate multiple classes at runtime * [`ProxyManager\GeneratorStrategy\FileWriterGeneratorStrategy`](https://github.com/Ocramius/ProxyManager/blob/master/src/ProxyManager/GeneratorStrategy/FileWriterGeneratorStrategy.php) which accepts a [`ProxyManager\FileLocator\FileLocatorInterface`](https://github.com/Ocramius/ProxyManager/blob/master/src/ProxyManager/FileLocator/FileLocatorInterface.php) instance as constructor parameter, and based on it, writes the generated class to a file before returning its code.
