.SH "DESCRIPTION"
.PP
This macro assigns the string constructed in type_string to the variable. The + operator and the CT macro can be used to construct the type string of an object. This is useful in identifying templates uniquely, as shown below.
.SH "EXAMPLE"
.PP
\fBC++ :\fR
.sp
.nf
template<class PLayout>
ostream& operator<<(ostream& out, const ParticleBase<PLayout>& P) {
  TAU_TYPE_STRING(taustr, "ostream (ostream, " + CT(P) + " )");
  TAU_PROFILE("operator<<()"taustr, TAU_PARTICLE | TAU_IO);
  ... 
}
    
.fi
.PP
When PLayout is instantiated with "
UniformCartesian<3U, double>
",this generates the unique template name:
.sp
.nf
operator<<() ostream const 
ParticleBase<UniformCartesian<3U, double> > )
    
.fi
.PP
The following example illustrates the usage of the CT macro to extract the name of the class associated with the given object using CT(*this);
.sp
.nf
template<class PLayout>
unsigned ParticleBase<PLayout7>::GetMessage(Message& msg, int node) {
  TAU_TYPE_STRING(taustr, CT(*this) + "unsigned (Message, int)");
  TAU_PROFILE("ParticleBase::GetMessage()", taustr, TAU_PARTICLE);
  ...
}
    
.fi
.PP
When PLayout is instantiated with "
UniformCartesian<3U, double>
",this generates the unique template name:
.sp
.nf
ParticleBase::GetMessage() ParticleBase<UniformCartesian<3U, 
double> > unsigned (Message, int)
