[Closed] Accessing Custom Attributes Paramblock

Jan 14, 2009 10:20 am

Hi all,

I have a problem accessing certain parts of a parameters block within a custom attributes.
For e.g. I want to know the type setting of a parameter inside the parameters block. Is there anyway I can access it? I need this as I need to know if a parameter even thou the value is in float, is it in radian(#float) or degree(#angle).

Thanks in advanced.

either parse the source, or use the pblock definition?


a = custattributes.getDef $ 1
<AttributeDef:test>
custAttributes.getDefSource a
"attributes test (
	parameters main (
		rad type:#float
		deg type:#angle
	)
)
"
custAttributes.getPBlockDefs a
#(#(#main, 0, 0, #(), #(#rad, #(#type, #float)), #(#deg, #(#type, #angle))))

or, if bored, parse the output of showproperties:


showproperties $.test
  .rad : float
  .deg : angle
false

Thanks for helping this out. I was hoping there’s some better or more elegant way of doing this. Accessing the Paramblock definition really doesn’t seems that neat to me but oh well, it works.
