SOP_Node::parsePrimitiveGroups() non-const GU_Detail

[nicholas_yue]

Hi

 

  I like to check/get a group of primitive from one of the SOP input

 

     const GU_Detail* gdp0 = inputGeo(0);

 

  but I see the following

 

const GA_PrimitiveGroup *parsePrimitiveGroups(const char *pattern, 

     GU_Detail *pgdp, 

     int allow_numeric=1,

     int ordered = 1,

     bool strict = false,

     int offset = 0);

 

  is there a reason for pgdp to be a non-const pointer ?

 

Cheers

Answering my own post :

 

Use

 

         const GA_PrimitiveGroup *guidesGrp = gdp0->findPrimitiveGroup("blah");

 

instead
