Constructor & Destructor Documentation

◆ ActionBase()

AlterTableHandler::ActionBase::ActionBase ( bool  null = false)

Definition at line 53 of file alter.cpp.

Definition at line 196 of file alter.h.

◆ debug()

void KexiDB::AlterTableHandler::ActionBase::debug ( const DebugOptions &  debugOptions = DebugOptions())
inline

Definition at line 187 of file alter.h.

◆ debugString()

virtual TQString KexiDB::AlterTableHandler::ActionBase::debugString ( const DebugOptions &  debugOptions = DebugOptions())
inlinevirtual

Definition at line 185 of file alter.h.

◆ isNull()

bool KexiDB::AlterTableHandler::ActionBase::isNull ( ) const
inline
Returns
true if the action is NULL; used in the Table Designer for temporarily collecting actions that have no effect at all.

Definition at line 169 of file alter.h.

◆ setAlteringRequirements()

void KexiDB::AlterTableHandler::ActionBase::setAlteringRequirements ( int  alteringRequirements)
inlineprotected

Sets requirements for altering; used internally by AlterTableHandler object.

Definition at line 193 of file alter.h.

◆ shouldBeRemoved()

virtual bool KexiDB::AlterTableHandler::ActionBase::shouldBeRemoved ( ActionDictDict &  fieldActions)
inlineprotectedvirtual

After calling simplifyActions() for each action, shouldBeRemoved() is called for them as an additional step. This is used for ChangeFieldPropertyAction items so actions that do not change property values are removed.

Reimplemented in KexiDB::AlterTableHandler::ChangeFieldPropertyAction.

Definition at line 209 of file alter.h.

◆ simplifyActions()

virtual void KexiDB::AlterTableHandler::ActionBase::simplifyActions ( ActionDictDict &  fieldActions)
inlineprotectedvirtual

Simplifies fieldActions dictionary. If this action has to be inserted Into the dictionary, an ActionDict is created first and then a copy of this action is inserted into it.

Reimplemented in KexiDB::AlterTableHandler::ChangeFieldPropertyAction, KexiDB::AlterTableHandler::RemoveFieldAction, KexiDB::AlterTableHandler::InsertFieldAction, and KexiDB::AlterTableHandler::MoveFieldPositionAction.

Definition at line 203 of file alter.h.

AlterTableHandler::ChangeFieldPropertyAction & AlterTableHandler::ActionBase::toChangeFieldPropertyAction ( )

Definition at line 64 of file alter.cpp.

◆ toInsertFieldAction()

AlterTableHandler::InsertFieldAction & AlterTableHandler::ActionBase::toInsertFieldAction ( )

Definition at line 78 of file alter.cpp.

◆ toMoveFieldPositionAction()

Definition at line 85 of file alter.cpp.

◆ toRemoveFieldAction()

AlterTableHandler::RemoveFieldAction & AlterTableHandler::ActionBase::toRemoveFieldAction ( )

Definition at line 71 of file alter.cpp.

◆ updateAlteringRequirements()

virtual void KexiDB::AlterTableHandler::ActionBase::updateAlteringRequirements ( )

Reimplemented in KexiDB::AlterTableHandler::RemoveFieldAction, KexiDB::AlterTableHandler::InsertFieldAction, and KexiDB::AlterTableHandler::MoveFieldPositionAction.

Definition at line 198 of file alter.h.

virtual tristate KexiDB::AlterTableHandler::ActionBase::updateTableSchema ( TableSchema &  table,
Field *  field,
TQMap< TQString, TQString > &  fieldMap 
)
inlineprotectedvirtual

Reimplemented in KexiDB::AlterTableHandler::InsertFieldAction.
