Constructor & Destructor Documentation

FieldList::FieldList ( bool  owner = false  ) 

Creates empty list of fields. If owner is true, the list will be owner of any added field, what means that these field will be removed on the list destruction. Otherwise, the list just points any field that was added.

See also:
isOwner()

Definition at line 29 of file fieldlist.cpp.

FieldList::FieldList ( const FieldList fl  ) 

Copy constructor.

Definition at line 38 of file fieldlist.cpp.

FieldList::~FieldList (  )  [virtual]

Destroys the list. If the list owns fields (see constructor), these are also deleted.

Definition at line 53 of file fieldlist.cpp.


Member Function Documentation

uint KexiDB::FieldList::fieldCount (  )  const [inline]

Returns:
number of fields in the list.

Definition at line 56 of file fieldlist.h.

FieldList & FieldList::addField ( Field field  ) 

Adds field at the and of field list.

Reimplemented in KexiDB::IndexSchema.

Definition at line 103 of file fieldlist.cpp.

FieldList & FieldList::insertField ( uint  index,
Field field 
) [virtual]

Inserts field into a specified position (index).

Note: You can reimplement this method but you should still call this implementation in your subclass.

Reimplemented in KexiDB::QuerySchema, and KexiDB::TableSchema.

Definition at line 68 of file fieldlist.cpp.

void FieldList::removeField ( KexiDB::Field field  )  [virtual]

Removes field from the field list. Use with care.

Note: You can reimplement this method but you should still call this implementation in your subclass.

Reimplemented in KexiDB::QuerySchema, and KexiDB::TableSchema.

Definition at line 108 of file fieldlist.cpp.

Field* KexiDB::FieldList::field ( uint  id  )  [inline]

Returns:
field id or NULL if there is no such a field.

Reimplemented in KexiDB::QuerySchema.

Definition at line 74 of file fieldlist.h.

Field * FieldList::field ( const QString &  name  )  [virtual]

Returns:
field with name name or NULL if there is no such a field.

Definition at line 118 of file fieldlist.cpp.

bool KexiDB::FieldList::hasField ( const Field field  )  [inline]

Returns:
true if this list contains given field.

Definition at line 80 of file fieldlist.h.

int KexiDB::FieldList::indexOf ( const Field field  )  [inline]

Returns:
first occurence of field in the list or -1 if this list does not contain this field.

Definition at line 84 of file fieldlist.h.

QStringList FieldList::names (  )  const

Returns:
list of field names for this list.

Definition at line 201 of file fieldlist.cpp.

Field::List * FieldList::autoIncrementFields (  ) 

Returns:
list of autoincremented fields. The list is owned by this FieldList object.

Reimplemented in KexiDB::QuerySchema.

Definition at line 240 of file fieldlist.cpp.

bool KexiDB::FieldList::isOwner (  )  const [inline]

Returns:
true if fields in the list are owned by this list.

Definition at line 97 of file fieldlist.h.

void FieldList::clear (  )  [virtual]

Removes all fields from the list.

Reimplemented in KexiDB::QuerySchema, and KexiDB::TableSchema.

Definition at line 58 of file fieldlist.cpp.

QString FieldList::debugString (  )  [virtual]

Returns:
String for debugging purposes.

Reimplemented in KexiDB::IndexSchema, KexiDB::QuerySchema, and KexiDB::TableSchema.

Definition at line 123 of file fieldlist.cpp.

void FieldList::debug (  ) 

Shows debug information about all fields in the list.

Definition at line 143 of file fieldlist.cpp.

FieldList * FieldList::subList ( const QString &  n1,
const QString &  n2 = QString::null,
const QString &  n3 = QString::null,
const QString &  n4 = QString::null,
const QString &  n5 = QString::null,
const QString &  n6 = QString::null,
const QString &  n7 = QString::null,
const QString &  n8 = QString::null,
const QString &  n9 = QString::null,
const QString &  n10 = QString::null,
const QString &  n11 = QString::null,
const QString &  n12 = QString::null,
const QString &  n13 = QString::null,
const QString &  n14 = QString::null,
const QString &  n15 = QString::null,
const QString &  n16 = QString::null,
const QString &  n17 = QString::null,
const QString &  n18 = QString::null 
)

Creates and returns list that contain fields selected by name. At least field (exising on this list) should be selected, otherwise NULL is returned. Returned FieldList object is not owned by any parent (so you need to destroy yourself) and Field objects included in it are not owned by it (but still as before, by 'this' object). Returned list can be usable e.g. as argument for Connection::insertRecord().

Definition at line 156 of file fieldlist.cpp.

FieldList * FieldList::subList ( const QStringList &  list  ) 

Like above, but with a QStringList

Definition at line 191 of file fieldlist.cpp.

QString FieldList::sqlFieldsList ( Driver driver  ) 

Returns:
a string that is a result of all field names concatenated and with "," between. This is usable e.g. as argument like "field1,field2" for "INSERT INTO (xxx) ..". The result of this method is effectively cached, and it is invalidated when set of fields changes (e.g. using clear() or addField()).

Definition at line 231 of file fieldlist.cpp.

static QString KexiDB::FieldList::sqlFieldsList ( Field::List list,
Driver driver 
) [static]

Like above, but thsi is convenient static function, so you can pass any list here.
