This struct provides a namespace for functions that manage the lifetime of, and access to, a process‐wide default bdlt::TimetableCache object. The default cache is initialized by an explicit call to the initialize class method, and destroyed by the destroy class method. The default cache may be initialized and destroyed multiple times during the lifetime of a process. The lifetimes of the timetable loader and memory allocator supplied to initialize must extend beyond the following (matching) call to destroy.

Description

destroy

Destroy the default TimetableCache object managed by this class. If the default cache is not in the initialized state, this method has no effect. Note that all addresses returned by earlier calls to instance are invalidated by this method.

initialize

initialize overloads

instance

Return an address providing modifiable access to the default TimetableCache object managed by this class, if the default cache is in the initialized state, and 0 otherwise. The cache obtains timetables using the loader that was supplied to the initialize method. Note that the returned address is invalidated by a subsequent call to destroy.
