BloombergLP::bdlt::TimetableCache::TimetableCache

Create a timetable cache with the specified loader and timeout.

Synopsis

Declared in <bdlt_timetablecache.h>

TimetableCache(
    TimetableLoader* loader,
    bsls::TimeInterval const& timeout,
    bslma::Allocator* basicAllocator = 0);

Description

Create an empty timetable cache that uses the specified loader to load timetables on demand and has the specified timeout interval indicating the length of time that timetables remain valid for subsequent retrieval from the cache after they have been loaded. Optionally specify a basicAllocator used to supply memory. If basicAllocator is 0, the currently installed default allocator is used. The behavior is undefined unless bsls::TimeInterval() <= timeout <= bsls::TimeInterval(INT_MAX, 0), and loader remains valid throughout the lifetime of this cache. Note that a timeout value of 0 indicates that a timetable will be loaded into the cache by each (successful) call to the getTimetable method.
