public static class OmSnapshotLocalDataYaml.YamlFactory extends org.apache.commons.pool2.BasePooledObjectFactory<org.yaml.snakeyaml.Yaml>
Factory class for constructing and pooling instances of the Yaml object. This class extends BasePooledObjectFactory to support object pooling, minimizing the expense of repeatedly creating and destroying Yaml instances. The Yaml instances created by this factory are customized to use a specific set of property and serialization/deserialization configurations. - BeanAccess is configured to access fields directly, allowing manipulation of private fields in objects. - The PropertyUtils allows read-only properties to be accessed. - Custom Representer and Constructor classes tailored to the OmSnapshotLocalData data structure are employed to customize how objects are represented in YAML. This class provides thread-safe pooling and management of Yaml instances, ensuring efficient resource usage in high-concurrency environments.
