Detailed Description

Abstract base class used for implementing table field-related actions.

Definition at line 248 of file KDbAlter.h.

Constructor & Destructor Documentation

◆ FieldActionBase() [1/2]

KDbAlterTableHandler::FieldActionBase::FieldActionBase ( const QString & fieldName,
int uid )

Definition at line 107 of file KDbAlter.cpp.

◆ ~FieldActionBase()

KDbAlterTableHandler::FieldActionBase::~FieldActionBase ( )

Definition at line 120 of file KDbAlter.cpp.

◆ FieldActionBase() [2/2]

KDbAlterTableHandler::FieldActionBase::FieldActionBase ( bool null)

, used for constructing null action

Definition at line 114 of file KDbAlter.cpp.

Member Function Documentation

◆ fieldName()

QString KDbAlterTableHandler::FieldActionBase::fieldName ( ) const
field name for this action

Definition at line 255 of file KDbAlter.h.

◆ setFieldName()

void KDbAlterTableHandler::FieldActionBase::setFieldName ( const QString & fieldName)

Sets field name for this action.

Definition at line 273 of file KDbAlter.h.

◆ uid()

int KDbAlterTableHandler::FieldActionBase::uid ( ) const
field's unique identifier This id is needed because in the meantime there can be more than one field sharing the same name, so we need to identify them unambiguously. After the (valid) altering is completed all the names will be unique.

Example scenario when user exchanged the field names:

  1. At the beginning: [field A], [field B]
  2. Rename the 1st field to B: [field B], [field B]
  3. Rename the 2nd field to A: [field B], [field A]

Definition at line 268 of file KDbAlter.h.

Member Data Documentation

◆ m_fieldUID

int KDbAlterTableHandler::FieldActionBase::m_fieldUID

field's unique identifier,
