Detailed Description

template<typename sun>
class gauge_field_base< sun >

Define a standard base gauge class. Gauge field types (represented, smeared, etc) inherit from this

Definition at line 11 of file gauge_field.h.

Member Typedef Documentation

gauge_type_flt

template<typename sun >

using gauge_field_base< sun >::gauge_type_flt = sun

If the base type is double, this will be the corresponding floating point type.

Definition at line 47 of file gauge_field.h.

Member Function Documentation

restore_backup()

template<typename sun >

virtual void gauge_field_base< sun >::restore_backup ( )

inlinevirtual

Restore the gauge field from the backup. Used when an HMC trajectory is rejected.

Reimplemented in gauge_field< matrix >, gauge_field< fund_type >, gauge_field< sun >, represented_gauge_field< repr >, and stout_smeared_field< sun >.

Definition at line 43 of file gauge_field.h.

Member Data Documentation

momentum

template<typename sun >

Field<sun> gauge_field_base< sun >::momentum[4]

Also create a momentum field. This is only allocated if necessary
