Enum Class Query.Mode

All Implemented Interfaces:
Serializable, Comparable<Query.Mode>, Constable
Enclosing interface:

public static enum Query.Mode extends Enum<Query.Mode>
The execution mode of the query. Note that the mode is merely a hint. A backend may at any time choose to execute the query in another mode (e.g. because the desired mode is not available for the storage backend). Also note that lazy loading is usually very slow, while loading pages on demand is very fast. The performance impact of eager loading may very outweight the "cheap" on-demand loading of pages.
