XmlCompression::XmlCompression()
virtual XmlCompression::~XmlCompression()

XmlCompression is a base class for implementations of custom compression for a container. Compression is only used by whole document storage containers. To use customized compression the implementation must be registered with the XmlManager using XmlManager::registerCompression and the container must be created by passing an XmlContainerConfig object to XmlManager::createContainer that includes the name under which the instance was registered. Compression is a persistent attribute of a container. A container created with custom compression requires that the same named compression instance be registered with the XmlManager or any attempt to open the container will fail.

XmlCompression instances must be free-threaded and safe to use concurrently.
