[ADMB Users] empty function in doubling.cpp

[William Stockhausen - NOAA Federal]

Hi,

I'm trying to set the initial values for a param_init_number_vector (p,
say) from a dvector (vls, say) in a function using the following:

p.set_initial_value(vls);

The actual function is:

void setInitVals(BoundedNumberVectorInfo* pI,
param_init_bounded_number_vector& p){
    int np = pI->getSize();
    if (np){
        dvector vls = pI->getInitVals();
        p.set_initial_value(vls);
        cout<<"vls = "<<vls<<endl;
        cout<<"p   = "<<p<<endl;
     }
}

where pI is a pointer to an object whose method getInitVals() returns a
dvector.

Everything compiles fine, but when I run the code,  the initial values for
p are not equal to vls (they're equal to the default initial values) after
running setInits.

Fortunately this caused my code to produce some really strange results so I
realized there was a problem. Using the ADMB website, I tracked down the
following:

The 'set_initial_value' method for param_init_bounded_number_vector is
defined in model45.cpp as

00008 00009 <http://www.admb-project.org/documentation/api/classparam__init__bounded__vector__vector.html#ad696a4660a01ad50266fcbafa7d3beb7>
void param_init_bounded_vector_vector::set_initial_value
<http://www.admb-project.org/documentation/api/classparam__init__bounded__vector__vector.html#ad696a4660a01ad50266fcbafa7d3beb7>(00010
  const double_index_type
<http://www.admb-project.org/documentation/api/classdouble__index__type.html>&
_it)00011  {00012     it
<http://www.admb-project.org/documentation/api/classparam__init__bounded__vector__vector.html#a106e1b4f5049a08386645afbb658384b>=new
double_index_type
<http://www.admb-project.org/documentation/api/classdouble__index__type.html>(_it);00013
 }00014


and the conversion of a dvector to double_index_type is defined in
doublind.cpp as

00057 00062 <http://www.admb-project.org/documentation/api/classdouble__index__type.html#a70db7015028be71be42cbc4c37b59319>
double_index_type::double_index_type
<http://www.admb-project.org/documentation/api/classdouble__index__type.html#a2265b2e72fbd497b8cd4d4688398957a>(const
dvector <http://www.admb-project.org/documentation/api/classdvector.html>&
x)00063   {00064     p
<http://www.admb-project.org/documentation/api/classdouble__index__type.html#ad1bebc88ffff9232f7502f2c764ee3f2>
= new dvector_index
<http://www.admb-project.org/documentation/api/classdvector__index.html>((const
dvector <http://www.admb-project.org/documentation/api/classdvector.html>&)(x));00065
  }00066


but the constructor for the dvector_index uses the copy constructor for
dvector

00184 00189 <http://www.admb-project.org/documentation/api/classdvector__index.html#aba2c20e6f7432a5b4441e828427ce6e7>
dvector_index::dvector_index
<http://www.admb-project.org/documentation/api/classdvector__index.html#aba2c20e6f7432a5b4441e828427ce6e7>(const
dvector <http://www.admb-project.org/documentation/api/classdvector.html>&
v) : dvector <http://www.admb-project.org/documentation/api/classdvector.html>(v)00190
{00191 }00192


which makes a shallow copy of v. Not sure why this doesn't work, but it
doesn't.

My immediate issue is that I want to put setInitVals(...) in a code
library--i.e., not in the tpl code and the usual methods for setting the
initial values (i.e., simple assignment by element) are private and only
work when the function is defined inside the tpl. The set_initial_value
method is public and SHOULD work anywhere  (but doesn't work in the tpl
code either).

Hope this can get fixed soon.
