/// @brief A module cache class.
|
|
///
|
|
/// Caches locally modules that are downloaded from remote targets.
|
|
/// Each cached module maintains 2 views:
|
|
/// - UUID view: /${CACHE_ROOT}/${PLATFORM_NAME}/.cache/${UUID}/${MODULE_FILENAME}
|
|
/// - Sysroot view: /${CACHE_ROOT}/${PLATFORM_NAME}/${HOSTNAME}/${MODULE_FULL_FILEPATH}
|
|
///
|
|
/// UUID views stores a real module file, whereas Sysroot view holds a symbolic
|
|
/// link to UUID-view file.
|
|
///
|
|
/// Example:
|
|
/// UUID view : /tmp/lldb/remote-linux/.cache/30C94DC6-6A1F-E951-80C3-D68D2B89E576-D5AE213C/libc.so.6
