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.
