Detailed Description

maintain a connection to an SQLite database

SQLite (http://www.sqlite.org) is a public-domain SQL database written in C++. It's small, fast, and can be easily embedded inside other applications. Its databases are stored in files.

This class provides a VTK interface to SQLite. You do not need to download any external libraries: we include a copy of SQLite 3.3.16 in VTK/Utilities/vtksqlite.

If you want to open a database that stays in memory and never gets written to disk, pass in the URL sqlite://:memory:; otherwise, specify the file path by passing the URL sqlite://<file_path>.

Thanks:: Thanks to Andrew Wilson and Philippe Pebay from Sandia National Laboratories for implementing this class.

◆ IsA()

virtual vtkTypeBool vtkSQLiteDatabase::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 vtkSQLiteDatabase * vtkSQLiteDatabase::SafeDownCast ( vtkObjectBase * o )

static

◆ NewInstanceInternal()

virtual vtkObjectBase * vtkSQLiteDatabase::NewInstanceInternal ( ) const

◆ NewInstance()

vtkSQLiteDatabase * vtkSQLiteDatabase::NewInstance ( ) const

◆ PrintSelf()

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

overridevirtual

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 vtkSQLDatabase.

◆ New()

static vtkSQLiteDatabase * vtkSQLiteDatabase::New ( )

static

◆ Open() [1/2]

bool vtkSQLiteDatabase::Open ( const char * password )

overridevirtual

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.

USE_EXISTING (default) - Fail if the file does not exist.
USE_EXISTING_OR_CREATE - Create a new file if necessary.
CREATE_OR_CLEAR - Create new or clear existing file.
CREATE - Create new, fail if file exists.

Implements vtkSQLDatabase.

◆ Open() [2/2]

bool vtkSQLiteDatabase::Open	(	const char *	password,
		int	mode
	)

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.

USE_EXISTING (default) - Fail if the file does not exist.
USE_EXISTING_OR_CREATE - Create a new file if necessary.
CREATE_OR_CLEAR - Create new or clear existing file.
CREATE - Create new, fail if file exists.

const char * vtkSQLiteDatabase::GetLastErrorText ( )

overridevirtual

Get the last error text from the database.

Implements vtkSQLDatabase.

◆ GetDatabaseType()

const char * vtkSQLiteDatabase::GetDatabaseType ( )

inlineoverridevirtual

String representing database type (e.g.

"sqlite").

Implements vtkSQLDatabase.

Definition at line 133 of file vtkSQLiteDatabase.h.

◆ vtkGetFilePathMacro()

vtkSQLiteDatabase::vtkGetFilePathMacro ( DatabaseFileName )

String representing the database filename.

◆ vtkSetFilePathMacro()

vtkSQLiteDatabase::vtkSetFilePathMacro ( DatabaseFileName )

String representing the database filename.

◆ GetURL()

vtkStdString vtkSQLiteDatabase::GetURL ( )

overridevirtual

Get the URL of the database.

Implements vtkSQLDatabase.

◆ GetColumnSpecification()

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

overridevirtual

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

NB: this method implements the SQLite-specific syntax:

vtkX3D::type

@ type

Definition: vtkX3D.h:522

vtkX3D::name

@ name

Definition: vtkX3D.h:225

Reimplemented from vtkSQLDatabase.

◆ ParseURL()

bool vtkSQLiteDatabase::ParseURL ( const char * url )

overrideprotectedvirtual

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.
