entryScanned

public void entryScanned(T entry,

Description copied from interface: ScanCallback

This will be called after an entry is successfully scanned with the row IDs that were used. Deduplication, if performed, occurs prior to calling this method.

Without or without de-duplication, row ids are not consolidate, thus each entry only contains one row id. If the entry is not de-dupped, then the entry this method is called for each duplicate, each with a different row id.

Specified by:

entryScanned in interface ScanCallback<T,GeoWaveRow>

Parameters:

entry - the entry that was ingested

row - the raw row scanned from the table for this entry
