The ParameterInfoProvider Object

The ParameterInfoProvider object provides a list of named Parameter objects within a patcher hierarchy, as well as information about specific Parameter objects. It can also notify when Parameter objects are added or removed from a patcher hierarchy.

ParameterInfoProvider Constructor

var pip = new ParameterInfoProvider(function);

The function argument specifies the function you want to execute to receive change notifications. The function may have a single argument, which is a ParameterInfoProviderData object.

Example:

function paramschanged(data) {
  post("something was added or removed, getting new list\n")
  if (data.added.length) {
    post(data.added.join(", ") + " added\n")
  }
  if (data.removed.length) {
    post(data.removed.join(", ") + " removed\n")
  }
}

pip = new ParameterInfoProvider(paramschanged)

var pip = new ParameterInfoProvider()
var info = pip.getinfo("live.dial") // the Parameter named 'live.dial'
// iterating the contents
for (var i in info) {
  post(i + ": " + info[i] + "\n")
}
// prints to the Max Console (for a default live.dial object)
// js: longname: live.dial
// js: shortname: live.dial
// js: scriptname: live.dial
// js: type: float
// js: visibility: automated
// js: min: 0
// js: max: 127
// js: exponent: 1
// js: maxobject: [object Maxobj]
