Constructor & Destructor Documentation

ClearSkyEphemeris()

rose::ClearSkyEphemeris::ClearSkyEphemeris ( const std::string &  rootUri, const path &  xdgDir, const std::string &  storeRoot, std::chrono::system_clock::duration  duration  )

inline

Constructor.

Parameters

rootUri	The base URI locating all the items manage by the cache.
xdgDir	The XDG compliant specification for the user caching directory. See rose::Environment.
storeRoot	A relative path from xdgDir that this cache will use.
duration	The period of time cache items should be considered valid before being reloaded.

Member Function Documentation

constructUrl()

std::string rose::ClearSkyEphemeris::constructUrl ( const local_id_t &  localId )

inlineoverridevirtual

Construct the appropriate URL for the item.

Default procedure is to append the local id to the rout URI.

Parameters

localId

The local id.

Returns

The constructed URL.

Reimplemented from rose::WebCache.
