Detailed Description

Public class that respresents a DDL parser.

This class represents a DDL parser. This class utilizes flex/bison for syntax/semantic processing and stores the parsed data (DDL blocks and tables) in a DdlFile object.

Constructor & Destructor Documentation

DDLParser::DDLParser	(	DdlFile *	ddlFileP,
		bool	verbose = `false`
	)

Constructs a DDL parser.

Parameters:

`[in]`	ddlFileP	- pointer to the DdlFile object that the DDL parser is to use to store the parsed data
`[in]`	verbose	- optional parameter that indicates whether parsing logging should be turned on (if true) or off (if false). If verbose is not spefified, logging is turned off.

Returns:: Not applicable

Precondition:: ddlFileP must not be NULL

Postcondition:: None

Exceptions:

EmptyValueException

- if ddlFileP is NULL

DDLParser::~DDLParser ( ) [virtual]

Destructs a DDL parser by releasing all the used resources.

Parameters:

Not applicable

Returns:: Not applicable

Precondition:: None

Postcondition:: None

Exceptions:

None

Member Function Documentation

void DDLParser::Parse	(	const string &	fileName,
		string &	diagnostics
	)

Parses the DDL file.

Parameters:

`[in]`	fileName	- relative or absolute name of the DDL file that is to be parsed.
`[out]`	diagnostics	- parsing result. If empty, parsing completed with no warnings or errors. If non-empty, there were parsing warnings and/or parsing errors.

Returns:: None

Precondition:: None

Postcondition:: None

Exceptions:

None

void DDLParser::Clear ( )

Method, not currently part of users public API, and will soon be re-examined.

Reimplemented from DDLScanner.
