[Libmesh-devel] function pointer

[Mathias N. <mne...@tu...>]

Hello!

I'm programming a Newmarksystem...

My question is, if it is possible to attach a "assemble function" which 
is a method of a class...

Example:

PoroNewmark
{
private:
// declaration of a function pointer
void (PoroNewmark::*funcP)( EquationSystems &es, const std::string& 
system_name );
public:
//...
//...
void MatrixAssembler( EquationSystems &es, const std::string& system_name );

};

PoroNewmark::PoroNewmark (...)
{
//...
//...
funcPtrAssembler = & PoroNewmark::MatrixAssembler

rNewmark_system.attach_assemble_function ( funcPtrAssembler);

//...
//...
}

This will giva a comilation error

$ make
creating dependencies for src/poro_newmark.C ...
make[1]: Entering directory `/../main'
compiling src/poro_newmark.C ...

Any suggestions?

Thanks in advance
