Detailed Description

The controller of CIF to DB data conversion process.

This class controls the conversion process of CIF data to DB loadable data. It provides methods for its construction/destruction, conversion of ASCII CIF files, conversion of serialized (binary) CIF files, conversion of in-memory CIF file objects, setting the working directory. Data conversion methods can be instructed to generate: only the data loading files, only the data loading shell scripts or both the data and scripts. DB server data loading is accomplished by executing the generated loading shell scripts, which utilize the data loading files, obtained during the conversion process.

Constructor & Destructor Documentation

DbLoader::DbLoader	(	SchemaMap &	schemaMapping,
		DbOutput &	dbOutput,
		bool	verbose = false,
		const string &	workDir = std::string()
	)

Constructs a CIF to DB controller object.

Parameters:

[in]	schemaMapping	- reference to the schema mapping object
[in]	dbOutput	- reference to the database output object
[in]	verbose	- optional parameter that indicates whether logging should be turned on (if true) or off (if false). If verbose is not specified, logging is turned off.
[in]	workDir	- optional parameter that indicates the working directory in which the files will be placed. If workDir is not specified, current process working directory is used.

Returns:

Not applicable

Precondition:

None

Postcondition:

None

Exceptions:

None

DbLoader::~DbLoader

(

)

[virtual]

Destructs a CIF to DB controller object.

Parameters:

Not applicable

Returns:

Not applicable

Precondition:

None

Postcondition:

None

Exceptions:

None

void DbLoader::AsciiFileToDb	(	const string &	asciiFile,
		const eConvOpt	convOpt
	)

Converts an ASCII CIF file to DB loadable data with/without generating loading scripts. The specified file is first parsed and then converted.

Parameters:

[in]	asciiFile	- indicates the name of the ASCII CIF file, which is to be converted.
[in]	convOpt	- indicates data conversion options: generate data only, generate data with loading scripts, generate loading scripts only.

Returns:

None

void DbLoader::FileObjToDb	(	CifFile &	cifFile,
		const eConvOpt	convOpt
	)

Converts an in-memory CIF file object to DB loadable data with/without generating loading scripts.

Parameters:

[in]	cifFile	- a reference to the in-memory CIF file object, which is to be converted.
[in]	convOpt	- indicates data conversion options: generate data only, generate data with loading scripts, generate loading scripts only.

Returns:

None

Precondition:

None

Postcondition:

Exceptions:

None

void DbLoader::SerFileToDb	(	const string &	serFile,
		const eConvOpt	convOpt
	)

Converts a serialized (binary) CIF file to DB loadable data with/without generating loading scripts. The specified file is de-serialized (without the need to parse it) and converted.

Parameters:

[in]	serFile	- indicates the name of the serialized (binary) CIF file, which is to be converted.
[in]	convOpt	- indicates data conversion options: generate data only, generate data with loading scripts, generate loading scripts only.

Returns:

None

Precondition:

None

Postcondition:

None

Exceptions:

None

void DbLoader::SetWorkDir

(

const string &

Sets the working directory in which the generated files will be placed.

Parameters:

[in]

workDir

- indicates the working directory in which the files will be placed.

Returns:

None

Precondition:
