Traversing patcher hierarchy
Jul 16 2014 | 2:01 pm
Hello,
Is there a way to improve this code? I'm trying to traverse a patcher hierarchy in order to get the value of a named object called "id" without knowing the number of parent patcher levels it may be located in. My solution is very lame and works only up to 6 levels, since I don't know how to apply the this.patcher.parentpatcher...getnamed() function recursively.
Thanks, Georg
function bang()
{
var id = this.patcher.parentpatcher.getnamed("id");
if (id == null){
id = this.patcher.parentpatcher.parentpatcher.getnamed("id");
if (id == null){
id = this.patcher.parentpatcher.parentpatcher.parentpatcher.getnamed("id");
if (id == null){
id = this.patcher.parentpatcher.parentpatcher.parentpatcher.parentpatcher.getnamed("id");
if (id == null){
id = this.patcher.parentpatcher.parentpatcher.parentpatcher.parentpatcher.parentpatcher.getnamed("id");
if (id == null){
id = this.patcher.parentpatcher.parentpatcher.parentpatcher.parentpatcher.parentpatcher.parentpatcher.getnamed("id");
if (id == null){
id = this.patcher.parentpatcher.parentpatcher.parentpatcher.parentpatcher.parentpatcher.parentpatcher.parentpatcher.getnamed("id");
}
else outlet(0,id.getvalueof())
}
else outlet(0,id.getvalueof())
}
else outlet(0,id.getvalueof())
}
else outlet(0,id.getvalueof())
}
else outlet(0,id.getvalueof())
}
else outlet(0,id.getvalueof())
}
- Jul 16 2014 | 2:31 pmhere is a js that returns the name of root patcher
function bang() { var prev = this; var owner = this.patcher.box; while (owner) { prev = owner; owner = owner.patcher.box; } if (prev) { outlet(0, prev.patcher.name); } }it should easily be adapted to match your needs...Mathieu - Jul 16 2014 | 2:36 pmThanks, I'll look into this. The problem I see (this may be unfounded) is that the object in question may not be on root level.Georg
