Detailed Description

Public class that respresents schema mapping configuration.

This class encapsulates schema mapping functionality. Schema mapping defines how mmCIF data gets converted into the database data. Schema mapping information is stored in a number of configuration tables that are located in a configuration CIF file. This class provides methods for reading the schema mapping information from the ASCII CIF file or serialized (binary) configuration CIF file, for revising the schema mapping information (based on the data), updating the schema mapping information, accessing the attributes information.

Constructor & Destructor Documentation

SchemaMapping::SchemaMapping	(	const string &	schemaFile = `String::Empty`,
		const string &	schemaFileOdb = `String::Empty`,
		bool	verbose = `false`
	)

Constructs a schema mapping object.

Parameters:

`[in]`	schemaFile	- optional parameter that indicates the name of the ASCII CIF file, which holds the schema mapping configuration information. If specified, schemaFile file is parsed and the schema mapping configuration information is taken from it.
`[in]`	schemaFileOdb	- optional parameter that indicates the name of the serialized CIF file, which holds the schema mapping configuration information. If schemaFile is not specified, schemaFileOdb is de-serialized and the schema mapping configuration information is taken from it. If both schemaFile and schemaFileOdb are specified, schemaFile is parsed, the schema mapping configuration information is taken from it and then serialized to schemaFileOdb file, at the end of processing.
`[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.

Returns:: Not applicable

Precondition:: schemaFile and schemaFileOdb cannot both be empty.

Postcondition:: None

Exceptions:

None

SchemaMapping::~SchemaMapping ( ) [virtual]

Destructs a schema mapping object, by releasing all the used resources.

Parameters:

Not applicable

Returns:: Not applicable

Precondition:: None

Postcondition:: None

Exceptions:

None

Member Function Documentation

void SchemaMapping::SetReviseSchemaMode ( bool mode = true )

Sets the schema revising mode. Schema revising is a process where the existing schema mapping information is being updated, by examining the attributes of the converted mmCIF file. Schema revising is needed in order to increase the length of database attributes in database schema/data file so that the data can be fully stored in the database.

Parameters:

[in] mode - optional parameter that indicates whether the schema revising should be turned on (if true) or off (if false). If mode is not specified, schema revising is turned on.

Returns:: None

Precondition:: None

Postcondition:: None

Exceptions:

None

bool SchemaMapping::GetReviseSchemaMode ( )

Retrieves schema revising mode.

Parameters:

None

Returns:: true - if schema revising is turned on
false - if schema revising is turned off

Precondition:: None

Postcondition:: None

Exceptions:

None

void SchemaMapping::ReviseSchemaMap ( const string & revisedSchemaFile )

Writes the revised schema mapping information to a file.

Parameters:

[in] revisedSchemaFile - indicates the name of the ASCII CIF file, to which the revised schema mapping information will be written to.

Returns:: None

Precondition:: None

Postcondition:: None

Exceptions:

None

void SchemaMapping::updateSchemaMapDetails ( SchemaMapping & revSchMap )

Updates the existing schema mapping object, with the revised information from the specified schema mapping object.

Parameters:

[in] revSchMap - reference to a revised schema mapping object.

Returns:: None

Precondition:: None

Postcondition:: None

Exceptions:

None

void SchemaMapping::CreateTables	(	CifFile &	cifFile,
		const string &	blockName
	)

In the specified CIF file object, creates tables that are specified in the schema mapping object.

Parameters:

`[in]`	cifFile	- reference to a CIF file object that will hold the data.
`[in]`	blockName	- the name of the data block

Returns:: None

Precondition:: None

Postcondition:: None

Exceptions:

None

void SchemaMapping::GetTableNames ( vector< string > & tableNames )

Retrieves names of all the tables in each data block, defined in schema mapping object.

Parameters:

[out] tableNames - retrieved table names

Returns:: None

Precondition:: None

Postcondition:: None

Exceptions:

None
