Methods in edu.caltech.nanodb.indexes with parameters of type TupleFile

Modifier and Type	Method	Description
static PageTuple	IndexUtils.findTupleInIndex(Tuple key, TupleFile idxTupleFile)	Given an index tuple-file and a search key, this method attempts to find the first tuple in the index that matches the search key.
