Detailed Description

A ListEditor is an auxiliary operator for Editor/EditForm I.E. it works on parameter values expressed as strings.

For a parameter which is a list, it may not be edited in once by just setting a new value (as a string)

Firstly, a list can be long (and tedious to be accessed flat) then requires a better way of accessing

Moreover, not only its VALUES may be changed (SetValue), but also its LENGTH : items may be added or removed ...

Hence, the way of editing a parameter as a list is :

An EditList is produced by the Editor, with a basic definition This definition (brought by this class) can be redefined Hence the Editor may produce a specific ListEditor as needed

Constructor & Destructor Documentation

◆ IFSelect_ListEditor() [1/2]

IFSelect_ListEditor::IFSelect_ListEditor ( )

Creates a ListEditor with absolutely no constraint.

◆ IFSelect_ListEditor() [2/2]

IFSelect_ListEditor::IFSelect_ListEditor ( const Handle< Interface_TypedValue > &  def,
const Standard_Integer  max = 0 
)

Creates a ListEditor, for which items of the list to edit are defined by <def>, and <max> describes max length : 0 (D) means no limit value > 0 means : no more the <max> items are allowed.

Member Function Documentation

◆ AddValue()

virtual Standard_Boolean IFSelect_ListEditor::AddValue ( const Handle< TCollection_HAsciiString > &  val,
const Standard_Integer  atnum = 0 
)
virtual

Adds a new item. By default appends (at the end of the list) Can insert before a given rank <num>, if positive Returns True when done. False if MaxLength may be overpassed or if <val> does not satisfy the definition.

◆ ClearEdit()

void IFSelect_ListEditor::ClearEdit ( )

Clears all editions already recorded.

◆ EditedValues()

Handle< TColStd_HSequenceOfHAsciiString > IFSelect_ListEditor::EditedValues ( ) const

Returns the result of the edition.

◆ IsAdded()

Standard_Boolean IFSelect_ListEditor::IsAdded ( const Standard_Integer  num) const

Tells if a value (in edited list) has been added (new one)

◆ IsChanged()

Standard_Boolean IFSelect_ListEditor::IsChanged ( const Standard_Integer  num) const

Tells if a value (in edited list) has been changed, i.e. either modified-value, or added.

◆ IsModified()

Standard_Boolean IFSelect_ListEditor::IsModified ( const Standard_Integer  num) const

Tells if a value (in edited list) has been modified-value (not added)

◆ IsTouched()

Standard_Boolean IFSelect_ListEditor::IsTouched ( ) const

Tells if at least one edition (SetValue-AddValue-Remove) has been recorded.

◆ LoadEdited()

virtual Standard_Boolean IFSelect_ListEditor::LoadEdited ( const Handle< TColStd_HSequenceOfHAsciiString > &  list)
virtual

Loads a new list to replace the older one, in once ! By default (can be redefined) checks the length of the list and the value of each item according to the def Items are all recorded as Modified.

If no def has been given at creation time, no check is done Returns True when done, False if checks have failed ... a specialisation may also lock it by returning always False ...

◆ LoadModel()

void IFSelect_ListEditor::LoadModel ( const Handle< Interface_InterfaceModel > &  model)

Loads a Model. It is used to check items of type Entity(Ident)

◆ LoadValues()

void IFSelect_ListEditor::LoadValues ( const Handle< TColStd_HSequenceOfHAsciiString > &  vals)

Loads the original values for the list Remark : If its length is mor then MaxLength, editions remain allowed, except Add.

◆ NbValues()

Standard_Integer IFSelect_ListEditor::NbValues ( const Standard_Boolean  edited = Standard_True) const

Returns count of values, edited (D) or original.

◆ OriginalValues()

Handle< TColStd_HSequenceOfHAsciiString > IFSelect_ListEditor::OriginalValues ( ) const

Returns the value from which the edition started.

◆ Remove()

virtual Standard_Boolean IFSelect_ListEditor::Remove ( const Standard_Integer  num = 0,
const Standard_Integer  howmany = 1 
)
virtual

Removes items from the list By default removes one item. Else, count given by <howmany> Remove from rank <num> included. By default, from the end Returns True when done, False (and does not work) if case of out of range of if <howmany> is greater than current length.

◆ SetTouched()

void IFSelect_ListEditor::SetTouched ( )

Declares this ListEditor to have been touched (whatever action)

◆ SetValue()

virtual Standard_Boolean IFSelect_ListEditor::SetValue ( const Standard_Integer  num,
const Handle< TCollection_HAsciiString > &  val 
)
virtual

Sets a new value for the item <num> (in edited list) <val> may be a Null Handle, then the value will be cleared but not removed Returns True when done. False if <num> is out of range or if <val> does not satisfy the definition.

◆ Value()

Handle< TCollection_HAsciiString > IFSelect_ListEditor::Value ( const Standard_Integer  num,
const Standard_Boolean  edited = Standard_True 
) const

Returns a value given its rank. Edited (D) or Original A Null String means the value is cleared but not removed.
