[Android.Runtime.Register("constrainField", "(Ljava/text/Format$Field;)V", "GetConstrainField_Ljava_text_Format_Field_Handler", ApiSince=31)]
public virtual void ConstrainField(Java.Text._Format.Field? field);

[<Android.Runtime.Register("constrainField", "(Ljava/text/Format$Field;)V", "GetConstrainField_Ljava_text_Format_Field_Handler", ApiSince=31)>]
abstract member ConstrainField : Java.Text._Format.Field -> unit
override this.ConstrainField : Java.Text._Format.Field -> unit

Parameters

field: _Format.Field

The field to fix when iterating.

Attributes: RegisterAttribute

Remarks

Sets a constraint on the field. When this instance of ConstrainedFieldPosition is passed to FormattedValue.nextPosition, positions are skipped unless they have the given field. Any previously set constraints are cleared. For example, to loop over all grouping separators:

ConstrainedFieldPosition cfpos;
cfpos.constrainField(NumberFormat.Field.GROUPING_SEPARATOR);
while (fmtval.nextPosition(cfpos)) {
  // handle the grouping separator position
}

Changing the constraint while in the middle of iterating over a FormattedValue does not generally have well-defined behavior.
