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.

Member Function Documentation

static int vtkPostgreSQLDatabase::IsTypeOf ( const char *  type )

static

virtual int vtkPostgreSQLDatabase::IsA ( const char *  name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkSQLDatabase.

static vtkPostgreSQLDatabase* vtkPostgreSQLDatabase::SafeDownCast ( vtkObjectBase *  o )

static

virtual vtkObjectBase* vtkPostgreSQLDatabase::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkSQLDatabase.

vtkPostgreSQLDatabase* vtkPostgreSQLDatabase::NewInstance

(

)

const

void vtkPostgreSQLDatabase::PrintSelf ( ostream &  os, vtkIndent  indent  )

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

static vtkPostgreSQLDatabase* vtkPostgreSQLDatabase::New ( )

static

bool vtkPostgreSQLDatabase::Open ( const char *  password = 0 )

virtual

Open a new connection to the database. You need to set the filename before calling this function. Returns true if the database was opened successfully; false otherwise.

Implements vtkSQLDatabase.

void vtkPostgreSQLDatabase::Close ( )

virtual

Close the connection to the database.

Implements vtkSQLDatabase.

bool vtkPostgreSQLDatabase::IsOpen ( )

virtual

Return whether the database has an open connection

Implements vtkSQLDatabase.

vtkSQLQuery* vtkPostgreSQLDatabase::GetQueryInstance ( )

virtual

Return an empty query on this database.

Implements vtkSQLDatabase.

virtual bool vtkPostgreSQLDatabase::HasError ( )

virtual

Did the last operation generate an error

Implements vtkSQLDatabase.

const char* vtkPostgreSQLDatabase::GetLastErrorText ( )

virtual

Get the last error text from the database

Implements vtkSQLDatabase.

virtual char* vtkPostgreSQLDatabase::GetDatabaseType ( )

virtual

String representing database type (e.g. "psql").

Implements vtkSQLDatabase.

virtual void vtkPostgreSQLDatabase::SetHostName ( const char *  )

virtual

The database server host name.

virtual char* vtkPostgreSQLDatabase::GetHostName ( )

virtual

The database server host name.

virtual void vtkPostgreSQLDatabase::SetUser ( const char *  )

virtual

The user name for connecting to the database server.

virtual char* vtkPostgreSQLDatabase::GetUser ( )

virtual

The user name for connecting to the database server.

virtual void vtkPostgreSQLDatabase::SetPassword ( const char *  )

virtual

The user's password for connecting to the database server.

virtual void vtkPostgreSQLDatabase::SetDatabaseName ( const char *  )

virtual

The name of the database to connect to.

virtual char* vtkPostgreSQLDatabase::GetDatabaseName ( )

virtual

The name of the database to connect to.

virtual void vtkPostgreSQLDatabase::SetConnectOptions ( const char *  )

virtual

Additional options for the database.

virtual char* vtkPostgreSQLDatabase::GetConnectOptions ( )

virtual

Additional options for the database.

void vtkPostgreSQLDatabase::SetServerPort ( int  _arg )

inlinevirtual

The port used for connecting to the database.

Definition at line 251 of file vtkPostgreSQLDatabase.h.

virtual int vtkPostgreSQLDatabase::GetServerPortMinValue ( )

inlinevirtual

The port used for connecting to the database.

Definition at line 126 of file vtkPostgreSQLDatabase.h.

virtual int vtkPostgreSQLDatabase::GetServerPortMaxValue ( )

inlinevirtual

The port used for connecting to the database.

Definition at line 130 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.

virtual vtkStdString vtkPostgreSQLDatabase::GetColumnSpecification ( vtkSQLDatabaseSchema *  schema, int  tblHandle, int  colHandle  )

virtual

Return the SQL string with the syntax to create a column inside a "CREATE TABLE" SQL statement. 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.

virtual void vtkPostgreSQLDatabase::SetDatabaseType ( const char *  )

protectedvirtual

virtual void vtkPostgreSQLDatabase::SetLastErrorText ( const char *  )

void vtkPostgreSQLDatabase::NullTrailingWhitespace ( char *  msg )
