List of lowerBound() Examples

Examples of lowerBound()

kodkod.instance.Bounds.lowerBound()
Returns the set of tuples that r must contain (the lower bound on r's contents). If r is not mapped by this, null is returned. @return r in this.relations => lowerBound[r], null
org.apache.hadoop.io.file.tfile.TFile.Reader.Scanner.lowerBound()
org.apache.hadoop.zebra.tfile.TFile.Reader.Scanner.lowerBound()
org.jquantlib.math.matrixutilities.Array.lowerBound()

Examples of kodkod.instance.Bounds.lowerBound()

          if (translBounds.lowerBound(r)!=translBounds.upperBound(r)) { // r may change
