Abstract inline measurements.
Inline measurement of glueball operators via colorstd::vector matrix elements.
unsigned long getFrequency(void) const
Tell me how often I should measure this beastie.
void operator()(const unsigned long update_no, XMLWriter &xml_out)
Do the measurement.
void func(const unsigned long update_no, XMLWriter &xml_out)
Do the measurement.
bool registerAll()
Register all the factories.
Asqtad Staggered-Dirac operator.
Definition: klein_gord.cc:10
::std::string string
Definition: gtest.h:1979
Hold group xml and type id.
void writeXML(XMLWriter &xml_out, const std::string &path) const
Read an XML group as a std::string.
