[Trilinos-Users] [EXTERNAL] iterating over parameter list elements

[Roger Pawlowski]

Hi Kevin,

The read only iterators are still there.  We use them in Panzer quite 
heavily.  Ross refactored the ParameterList recently but he made sure to 
preserve this functionality.

According to the doxygen for development branch built last night:

http://trilinos.sandia.gov/packages/docs/dev/packages/teuchos/doc/html/classTeuchos_1_1ParameterList.html#ac9143b7e1038258a1b05974d7ea3c173

ConstIterator 
<http://trilinos.sandia.gov/packages/docs/dev/packages/teuchos/doc/html/classTeuchos_1_1FilteredIterator.html> 
begin 
<http://trilinos.sandia.gov/packages/docs/dev/packages/teuchos/doc/html/classTeuchos_1_1ParameterList.html#ac9143b7e1038258a1b05974d7ea3c173> 
() const  An iterator pointing to the first entry.

ConstIterator

end 
<http://trilinos.sandia.gov/packages/docs/dev/packages/teuchos/doc/html/classTeuchos_1_1ParameterList.html#aa48925320408aa65a077365d7e678136> 
() const  An iterator pointing beyond the last entry.

Were there other functions you were thinking of?
