Detailed Description

(Internal) Class implements binary search on file

File consists of records, which structure is defined by creating class inherited from EBinaryRecord interface. File must be sorted by search key.

EBinaryRecordCol EBinarySortedFileSearch::Find ( std::string key )

Searching by key

Parameters

key	= search key (key "--all" returns all records from file)

Returns: Collection of all records with key "key". These record ARE NOT deleted by EBinarySortedFileSearch!

Here is the call graph for this function:

EBinaryRecordCol EBinarySortedFileSearch::Find ( std::string key )

Searching by key

Parameters

key	= search key (key "--all" returns all records from file)

Returns: Collection of all records with key "key". These record ARE NOT deleted by EBinarySortedFileSearch!

bool EBinarySortedFileSearch::Init	(	std::string	path,
		EBinaryRecord *	prototype,
		unsigned short	headSize = `0`
	)

Inicialization of search engine

Parameters

path	= absolute path of file including its name ( e.g. "/tmp/records.bin" )
prototype	= instance of class inherited from EBinaryRecord which defines the structure of data in file (deleted by EBinarySortedFileSearch)
headSize	= size of file header in bytes (0 = file doesn't have any header)

bool EBinarySortedFileSearch::Init	(	std::string	path,
		EBinaryRecord *	prototype,
		unsigned short	headSize = `0`
	)

Inicialization of search engine

Parameters

path	= absolute path of file including its name ( e.g. "/tmp/records.bin" )
prototype	= instance of class inherited from EBinaryRecord which defines the structure of data in file (deleted by EBinarySortedFileSearch)
headSize	= size of file header in bytes (0 = file doesn't have any header)
