getterSetter

typedef

The getterSetter argument passed to registerConverter.

`Object`

An object with a get and set method that get converted to a two-way helper.

stache.registerConverter("numberToString", {
 get: function(fooCompute) {
    return "" + fooCompute();
 },
 set: function(newVal, fooCompute) {
    fooCompute(+newVal);
 }
});

A getterSetter object provides:

A get method that returns the value of the left value given the arguments passed on the right.
a set method that updates one or multiple of the right arguments computes given a new left value.

Options

get {function(args...)}:
Takes the arguments from a Call Expression and returns a value.

An argument is a compute if the argument has been marked with a tilde (~) prefix, otherwise the value of the argument is the same as the value of the corresponding scope property. At least one argument should be a compute so set can update the value.
set {function(setValue, args...)}:
Takes the new value of the left side of a {(two-way)} binding followed by the other arguments to the Call Expression. This should change one of the compute arguments.
