backConverter property

BackConversion? get backConverter

Gets or sets a converter function to apply to the GraphObject property value in order to produce the value to set to a data property. This conversion function is only used in a TwoWay binding, when transferring a value from the target to the source. The default value is null -- no conversion takes place. Otherwise the value should be a function that takes one or two arguments and returns the desired value. However, the return value is ignored when the #sourceProperty is the empty string.

Conversion functions must not have any side-effects other than setting the source property.

The function is passed the value from the target (the first argument), the source Panel#data object (the second argument), and the Model (the third argument). If the #sourceProperty is a property name, that property is set to the function's return value. If the #sourceProperty is the empty string, the function should modify the second argument, which will be the source data object.

Implementation

_i3.BackConversion get backConverter => (
      _i3.Model p2, [
      _i2.dynamic p0,
      _i2.dynamic p1,
    ]) =>
        _i4.callMethod(
          _i4.getProperty(
            this,
            'backConverter',
          ),
          r'call',
          [
            this,
            p0,
            p1,
            p2,
          ],
        );

set backConverter (BackConversion? value)

Implementation

set backConverter(_i3.BackConversion value) {
  _i4.setProperty(
    this,
    'backConverter',
    value == null ? _i5.undefined : _i4.allowInterop(value),
  );
