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.

Member Function Documentation

◆ IsTypeOf()

static vtkTypeBool vtkSQLiteDatabase::IsTypeOf ( const char *  type)
static

◆ 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.

◆ SafeDownCast()

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

◆ NewInstanceInternal()

virtual vtkObjectBase* vtkSQLiteDatabase::NewInstanceInternal ( ) const
protectedvirtual

Reimplemented from vtkSQLDatabase.

◆ 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 
)

◆ Close()

void vtkSQLiteDatabase::Close ( )
overridevirtual

Close the connection to the database.

Implements vtkSQLDatabase.

◆ IsOpen()

bool vtkSQLiteDatabase::IsOpen ( )
overridevirtual

Return whether the database has an open connection.

Implements vtkSQLDatabase.

◆ GetQueryInstance()

vtkSQLQuery* vtkSQLiteDatabase::GetQueryInstance ( )
overridevirtual

Return an empty query on this database.

Implements vtkSQLDatabase.

◆ GetTables()

vtkStringArray* vtkSQLiteDatabase::GetTables ( )
overridevirtual

Get the list of tables from the database.

Implements vtkSQLDatabase.

◆ GetRecord()

vtkStringArray* vtkSQLiteDatabase::GetRecord ( const char *  table)
overridevirtual

Get the list of fields for a particular table.

Implements vtkSQLDatabase.

◆ IsSupported()

bool vtkSQLiteDatabase::IsSupported ( int  feature)
override

Return whether a feature is supported by the database.

◆ HasError()

bool vtkSQLiteDatabase::HasError ( )
overridevirtual

Did the last operation generate an error.

Implements vtkSQLDatabase.

◆ GetLastErrorText()

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.

◆ GetDatabaseFileName()

virtual char* vtkSQLiteDatabase::GetDatabaseFileName ( )
virtual

String representing the database filename.

◆ SetDatabaseFileName()

virtual void vtkSQLiteDatabase::SetDatabaseFileName ( const char *  )
virtual

◆ 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: <column name>=""> <column type>=""> <column attributes>="">

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.
