示例1: makeExtendedFilter
import org.apache.cassandra.db.filter.ExtendedFilter; //导入方法依赖的package包/类
/**
* Allows generic range paging with the slice column filter.
* Typically, suppose we have rows A, B, C ... Z having each some columns in [1, 100].
* And suppose we want to page through the query that for all rows returns the columns
* within [25, 75]. For that, we need to be able to do a range slice starting at (row r, column c)
* and ending at (row Z, column 75), *but* that only return columns in [25, 75].
* That is what this method allows. The columnRange is the "window" of columns we are interested
* in each row, and columnStart (resp. columnEnd) is the start (resp. end) for the first
* (resp. last) requested row.
