◆ ~ActionBase()

KDbAlterTableHandler::ActionBase::~ActionBase ( )

Definition at line 67 of file KDbAlter.cpp.

KDbAlterTableHandler::ActionBase::ActionBase ( bool null)

, used for constructing null action

Definition at line 60 of file KDbAlter.cpp.

Member Function Documentation

◆ alteringRequirements()

int KDbAlterTableHandler::ActionBase::alteringRequirements ( ) const

Definition at line 204 of file KDbAlter.h.

◆ debug()

void KDbAlterTableHandler::ActionBase::debug ( const DebugOptions & debugOptions = DebugOptions())
add QDebug operator <<

Definition at line 99 of file KDbAlter.cpp.

◆ debugString()

virtual QString KDbAlterTableHandler::ActionBase::debugString ( const DebugOptions & debugOptions = DebugOptions())

Definition at line 188 of file KDbAlter.h.

◆ isNull()

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

Definition at line 170 of file KDbAlter.h.

◆ setAlteringRequirements()

void KDbAlterTableHandler::ActionBase::setAlteringRequirements ( int alteringRequirements)

Sets requirements for altering; used internally by KDbAlterTableHandler object.

Definition at line 200 of file KDbAlter.h.

◆ shouldBeRemoved()

virtual bool KDbAlterTableHandler::ActionBase::shouldBeRemoved ( ActionDictDict * fieldActions)

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 KDbAlterTableHandler::ChangeFieldPropertyAction.

Definition at line 221 of file KDbAlter.h.

◆ simplifyActions()

virtual void KDbAlterTableHandler::ActionBase::simplifyActions ( ActionDictDict * fieldActions)

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 KDbAlterTableHandler::ChangeFieldPropertyAction, KDbAlterTableHandler::InsertFieldAction, KDbAlterTableHandler::MoveFieldPositionAction, and KDbAlterTableHandler::RemoveFieldAction.

Definition at line 213 of file KDbAlter.h.

◆ toChangeFieldPropertyAction()

KDbAlterTableHandler::ChangeFieldPropertyAction & KDbAlterTableHandler::ActionBase::toChangeFieldPropertyAction ( )

Definition at line 71 of file KDbAlter.cpp.

◆ toInsertFieldAction()

KDbAlterTableHandler::InsertFieldAction & KDbAlterTableHandler::ActionBase::toInsertFieldAction ( )

Definition at line 85 of file KDbAlter.cpp.

◆ toMoveFieldPositionAction()

KDbAlterTableHandler::MoveFieldPositionAction & KDbAlterTableHandler::ActionBase::toMoveFieldPositionAction ( )

Definition at line 92 of file KDbAlter.cpp.

◆ toRemoveFieldAction()

KDbAlterTableHandler::RemoveFieldAction & KDbAlterTableHandler::ActionBase::toRemoveFieldAction ( )

Definition at line 78 of file KDbAlter.cpp.

◆ updateAlteringRequirements()

virtual void KDbAlterTableHandler::ActionBase::updateAlteringRequirements ( )

◆ updateTableSchema()

virtual tristate KDbAlterTableHandler::ActionBase::updateTableSchema ( KDbTableSchema * table,
KDbField * field,
QHash< QString, QString > * fieldHash )

Reimplemented in KDbAlterTableHandler::InsertFieldAction.
