struct DeletedEvents __attribute__

(

(packed)

)

void CardEventCreator::AddCardEvent

(

CardEvent __EDATAPTR

cardEvent

)

Adds card event to collection

Parameters

cardEvent

: pointer to CardEvent instance - card event to add

CardEventCreator

(

)

static bool CleanEventFile ( __ESTRING  path )

static

CleanEventFile Cleans event file = removes records in .dat file which dont have twin in .idx file. In fact it removes all processed events since last cleaning.

Parameters

path	: string - path to event file including file name without extension (e.g. "/opt/emtest/var/events")

Returns

bool - false = file not found true = success

void CardEventCreator::GetBytes	(	__EBYTEARR __EDATAPTR __EVALREF	idxFileBuffer,
		__EBYTEARR __EDATAPTR __EVALREF	datFileBuffer,
		unsigned long __EVALREF	idxFileSize,
		unsigned long __EVALREF	datFileSize
	)

OBSOLETE - use GetBytes( __EBYTEARR __EDATAPTR __EVALREF idx_dat_FileBuffer ) instead

Here is the call graph for this function:

unsigned long CardEventCreator::GetBytes

(

__EBYTEARR __EDATAPTR __EVALREF

idx_dat_FileBuffer

)

GetBytes Creates event file buffer containing all parts

CardEventReader::SplitEventFile

Parameters

idx_dat_FileBuffer

: data stream [output parameter] - event file buffer

Returns

unsigned long - size of event file buffer returned as param

Here is the call graph for this function:

unsigned long GetValidFrom

(

)

Returns event file validity start (usually creation date)

See also

SetValidFrom

Returns

unsigned long - event file validity start as unix timestamp (number of seconds since January 1st, 1970)

unsigned long GetValidTo

(

)

Returns event file validity end (can be 0)

See also

SetValidTo

Returns

unsigned long : event file validity end as unix timestamp (number of seconds since January 1st, 1970)

void Init

(

__ESTRING

path

)

Here is the caller graph for this function:

static int MergeCumulative ( __ESTRING  pathOld, __ESTRING  pathUpd, unsigned long &  maxEventNumberInUpdate  )

static

Method merges current event files with downloaded incremental files and saves it under current file name (pathOld).
Downloading whole event file causes a large traffic and takes a long time on slow connection so there is a possibility to download only 'increments' - client provides the highest event ID he has already downloaded and webservice send only newer events. These increments have to be merged with old files then. This merging method merges index files including deleting already processed events, but .dat file keeps untouched except appending new events to the end of file. It's because of very long merging times on some devices. Therefore .dat files should be cleaned sometimes - best way is to delete event files and download brand new files. Or CleanEventFile method can be called.

Parameters

pathOld	: string - absulute path to current event file without any extension (e.g. /tmp/events)
pathUpd	: string - absolute path to downloaded increments without any extension (e.g. /tmp/events_tmp)
maxEventNumberInUpdate	: unsigned long [output parameter] - the largest event number in update files (can be 0 if 'pathOld' event files not found - in this case client has to find out max event number by himself)

Returns

int - error code (0 if OK)

Here is the caller graph for this function:

void SetFileType

(

char

type

)

Set file type (used by incremental downloading of event files from webservice)

MergeCumulative

Parameters

type	: char - file type 0 - incremental event file (should be merged) 1 - whole event file (should NOT be merged - original file should be replaced)

void SetValidFrom

(

unsigned long

from

)

Sets event file validity start (usually creation date)

See also

GetValidFrom

Parameters

from	: unsigned long - event file validity start as unix timestamp (number of seconds since January 1st, 1970)

void SetValidTo

(

unsigned long

to

)

Sets event file validity end (can be 0)
