PipeTransform

To create a Pipe, you must implement this interface.

Angular invokes the transform method with the value of a binding as the first argument, and any parameters as the second argument in list form.

Syntax

value | pipeName[:arg0[:arg1...]]

Example

The RepeatPipe below repeats the value as many times as indicated by the first argument:

import 'package:angular2/core.dart' show Pipe, PipeTransform;
 
@Pipe(name: 'repeat')
class RepeatPipe implements PipeTransform {
  transform(dynamic value, int times) => '$value' * times;
}

Invoking {{ 'ok' | repeat:3 }} in a template produces okokok.
