Detailed Description

Abstract base class used for implementing all the AlterTable actions.

Definition at line 158 of file KDbAlter.h.

Constructor & Destructor Documentation

◆ ActionBase()

KDbAlterTableHandler::ActionBase::ActionBase ( bool  null)
explicitprotected

, used for constructing null action

Definition at line 60 of file KDbAlter.cpp.

Member Function Documentation

◆ debug()

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

Definition at line 99 of file KDbAlter.cpp.

◆ isNull()

bool KDbAlterTableHandler::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 170 of file KDbAlter.h.

◆ setAlteringRequirements()

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

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)
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 KDbAlterTableHandler::ChangeFieldPropertyAction.

Definition at line 221 of file KDbAlter.h.

◆ simplifyActions()

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

Definition at line 213 of file KDbAlter.h.
