class QgsFieldMappingModel : QAbstractTableModel
{
%Docstring(signature="appended")
Holds mapping information for mapping from one set of
:py:class:`QgsFields` to another.

For each set of "destination" fields an expression defines how to obtain
the values of the "destination" fields.

The model can be optionally set "editable" allowing to modify all the
fields, by default only the mapping expression is editable.

%Docstring
Constructs a QgsFieldMappingModel from a set of ``sourceFields`` and
``destinationFields``, initial values for the expressions can be
optionally specified through ``expressions`` which is a map from the
original field name to the corresponding expression. A ``parent`` object
can be also specified.

%Docstring
Sets the list of ``nativeTypes`` supported by a data provider.

If this list is non-empty, then the destination field types will be
populated accordingly. If the list is empty, then a set of default
native types will be used instead.

Returns ``True`` if the destination fields are editable

Sets the destination fields editable state to ``editable``

Returns a static map of supported data types

Returns a map of destination field name to :py:class:`QgsProperty`
definition for field value, representing the current status of the
model.

Sets a map of destination field name to :py:class:`QgsProperty`
definition for field value.

%Docstring
Appends a new ``field`` to the model, with an optional ``expression``
%End

%Docstring
Removes the field at ``index`` from the model, returns ``True`` on
success
%End

Moves down the field at ``index``
%End

Moves up the field at ``index``

Set source fields to ``sourceFields``

Returns the context generator with the source fields

Sets the base expression context ``generator``, which will generate the
expression contexts for expression based widgets used by the model.

%Docstring
Set destination fields to ``destinationFields``, initial values for the

a map from the original field name to the corresponding expression.
