Function Documentation

ZFIORemoveOutdate()

zfautoT< ZFTaskId > ZFIORemoveOutdate ( const ZFPathInfo & pathInfo, const ZFListener & filter = (zft_zfnull), zftimet outdate = (zftimetOneWeek()) )

extern

remove outdated files

filter would be called before removing each file, param0 is v_ZFPathInfo that describe the child file, and param1 is a v_zfstring stores the relative path to source pathInfo
impl can:

• set ZFArgs::eventFiltered if process done
• set ZFArgs::result to any valid object, to prevent the file from being removed

ZFIORemoveEmptyDir()

zfautoT< ZFTaskId > ZFIORemoveEmptyDir ( const ZFPathInfo & pathInfo, const ZFListener & filter = (zft_zfnull) )

extern

remove empty dir, excluding the pathInfo itself

filter would be called before removing each dir, param0 is v_ZFPathInfo that describe the child file or dir, and param1 is a v_zfstring stores the relative path to source pathInfo
impl can:

• set ZFArgs::param0 or ZFArgs::param1 to null, to prevent checking children of the file or dir (if isRecursive)
• set ZFArgs::eventFiltered if process done
• set ZFArgs::result to any valid object, to prevent the dir from being removed

ZFIOForEachAsync()

zfautoT< ZFTaskId > ZFIOForEachAsync ( const ZFPathInfo & pathInfo, const ZFListener & fileCallback, const ZFListener & finishCallback = (zft_zfnull), zfbool isRecursive = (_ZFT_t_zftrue) )

extern

async version for ZFIOForEach to prevent blocking UI update when performing heavy task

fileCallback is same as ZFIOForEach, but would be called with some delay between each call for each file/dir

fileCallback's sender would be the v_ZFIOFindData (may be null if pathInfo already points to a file), param0 is v_ZFPathInfo that describe the child file or dir, and param1 is a v_zfstring stores the relative path to source pathInfo (may be empty string if pathInfo already points to a file)
impl can:

• set ZFArgs::param0 to null, to prevent checking children of the file or dir (if isRecursive)
• set ZFArgs::param0 to a ZFTask, to perform custom task
• set ZFArgs::eventFiltered if process done
• set ZFArgs::result, which would be passed as param1 to finishCallback, note: the result would be kept acrossing different calls

finishCallback's param0 would be a v_ZFResultType indicates result type, param1 would be the result passed from fileCallback

ZFStyleLoadAsync()

zfautoT< ZFTaskId > ZFStyleLoadAsync ( const ZFPathInfo & pathInfo, const ZFListener & finishCallback = (zft_zfnull) )

extern

async version of ZFStyleLoad

all items would still be loaded in main thread, but would wait some time between each load task, so that it's possible to update your UI during heavy load task, item load events:

• ZFGlobalEvent::E_ZFStyleLoadItemBegin
• ZFGlobalEvent::E_ZFStyleLoadItemEnd

finishCallback's param0 would be a v_ZFResultType indicates result type
