Member Function Documentation

PVTimestampFilterPtr epics::pvCopy::PVTimestampFilter::create ( const std::string &  requestValue, const epics::pvData::PVFieldPtr &  master  )

static

Create a PVTimestampFilter.

Parameters

requestValue	The value part of a name=value request option.
master	The field in the master PVStructure to which the PVFilter will be attached.

Returns

The PVFilter. A null is returned if master or requestValue is not appropriate for the plugin.

bool epics::pvCopy::PVTimestampFilter::filter ( const epics::pvData::PVFieldPtr &  pvCopy, const epics::pvData::BitSetPtr &  bitSet, bool  toCopy  )

virtual

Perform a filter operation

Parameters

pvCopy	The field in the copy PVStructure.
bitSet	A bitSet for copyPVStructure.
toCopy	(true,false) means copy (from master to copy,from copy to master)

Returns

if filter (modified, did not modify) destination. Null is returned if master or requestValue is not appropriate for the plugin.
