Detailed Description

maintain a connection to a PostgreSQL database

PostgreSQL (http://www.postgres.org) is a BSD-licensed SQL database. It's large, fast, and can not be easily embedded inside other applications. Its databases are stored in files that belong to another process.

This class provides a VTK interface to PostgreSQL. You do need to download external libraries: we need a copy of PostgreSQL 8 (currently 8.2 or 8.3) so that we can link against the libpq C interface.

Thanks:: Thanks to David Thompson and Andy Wilson from Sandia National Laboratories for implementing this class.

virtual int vtkPostgreSQLDatabase::GetServerPortMinValue ( )

inlinevirtual

The port used for connecting to the database.

Definition at line 152 of file vtkPostgreSQLDatabase.h.

virtual int vtkPostgreSQLDatabase::GetServerPort ( )

virtual

The port used for connecting to the database.

virtual vtkStdString vtkPostgreSQLDatabase::GetURL ( )

virtual

Get a URL referencing the current database connection.

This is not well-defined if the HostName and DatabaseName have not been set. The URL will be of the form 'psql://'[username[':'password]'@']hostname[':'port]'/'database .

Implements vtkSQLDatabase.

vtkStringArray* vtkPostgreSQLDatabase::GetTables ( )

virtual

Get the list of tables from the database.

Implements vtkSQLDatabase.

vtkStringArray* vtkPostgreSQLDatabase::GetRecord ( const char * table )

virtual

Get the list of fields for a particular table.

Implements vtkSQLDatabase.

bool vtkPostgreSQLDatabase::IsSupported ( int feature )

Return whether a feature is supported by the database.

vtkStringArray* vtkPostgreSQLDatabase::GetDatabases ( )

Return a list of databases on the server.

bool vtkPostgreSQLDatabase::CreateDatabase	(	const char *	dbName,
		bool	dropExisting = `false`
	)

Create a new database, optionally dropping any existing database of the same name.

Returns true when the database is properly created and false on failure.

bool vtkPostgreSQLDatabase::DropDatabase ( const char * dbName )

Drop a database if it exists.

Returns true on success and false on failure.

NB: this method implements the PostgreSQL-specific syntax: <column name>=""> <column type>=""> <column attributes>="">

Reimplemented from vtkSQLDatabase.

virtual bool vtkPostgreSQLDatabase::ParseURL ( const char * url )

virtual

Overridden to determine connection parameters given the URL.

This is called by CreateFromURL() to initialize the instance. Look at CreateFromURL() for details about the URL format.

Implements vtkSQLDatabase.

void vtkPostgreSQLDatabase::UpdateDataTypeMap ( )

protected

Create or refresh the map from Postgres column types to VTK array types.

Postgres defines a table for types so that users may define types. This adaptor does not support user-defined types or even all of the default types defined by Postgres (some are inherently difficult to translate into VTK since Postgres allows columns to have composite types, vector-valued types, and extended precision types that vtkVariant does not support.

This routine examines the pg_types table to get a map from Postgres column type IDs (stored as OIDs) to VTK array types. It is called whenever a new database connection is initiated.
