All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`long`	`getBuildTime()` Time required to "build" (load, create, filter, ...) the data set.
`long`	`getIndexSize()` Return the estimated memory (in bytes) the data set index is consuming.
`DataSetIndexElement`	`getLessReused()` An index reference to the less reused element.
`DataSetIndexElement`	`getLongestBuild()` An index reference to the element that takes more time to get instantiated.
`DataSetIndexElement`	`getMostReused()` An index reference to the most reused element.
`int`	`getNumberOfAggFunctions()` Total number of aggregate function calculations executed over the data set
`int`	`getNumberOfFilterOps()` Total number of filter operations executed over the data set
`int`	`getNumberOfGroupOps()` Total number of group operations over the data set
`int`	`getNumberOfSortOps()` Total number of sort operations executed over the data set
`double`	`getReuseRate()` The ratio between the reuse time and the build time.
`long`	`getReuseTime()` The real usage time this element would have if was not indexed.
`DataSetIndexElement`	`getShortestBuild()` An index reference to the element that takes less time to get instantiated.
`String`	`toString(String sep)` Prints a stats summary.
