package format

Contains the Format API used by Form.

For example, to define a custom formatter:

val signedIntFormat = new Formatter[Int] {

def bind(key: String, data: Map[String, String]) = {
  stringFormat.bind(key, data).right.flatMap { value =>
    scala.util.control.Exception.allCatch[Int]
      .either(java.lang.Integer.parseInt(value))
      .left.map(e => Seq(FormError(key, "error.signedNumber", Nil)))
  }
}

def unbind(key: String, value: Long) = Map(
  key -> ((if (value<0) "-" else "+") + value)
)
}
