Member Function Documentation

template<class oType> unsigned long GrMC4020Source< oType >::index_sub (  unsigned long  a, unsigned long  b )  [protected]

template<class oType> void GrMC4020Source< oType >::initOutputBuffer (  int  n  )  [virtual]

Reimplemented from VrSigProc.

template<class oType> virtual float GrMC4020Source< oType >::memoryTouched (   )  [inline, virtual]

Returns the total number of bytes read (ignores written bytes) per second by the upstream chain ending with this module zero has a special meaning (no outputs in cache) Reimplemented from VrSigProc.

template<class oType> virtual const char* GrMC4020Source< oType >::name (   )  [inline, virtual]

default name for a module (override with actual name) Reimplemented from VrSource< oType >.

template<class oType> unsigned long GrMC4020Source< oType >::npages_to_free (   )  [protected]

Determine how many pages at the beginning of the region that the driver has allocated to us we no longer need. The earliest VrSampleIndex in use is given by proc_minRP(). We use this and sample_index (the VrSampleIndex of the beginning of the active portion of the driver buffer) to see if we can return some pages to the driver.

template<class oType> int GrMC4020Source< oType >::work2 (  VrSampleRange  output, void *  o[] )  [virtual]

Implements VrSource< oType >.
