UseCompoundFile() public method

Returns true if a new segment (regardless of its origin) should use the compound file format. The default implementation returns true iff the size of the given mergedInfo is less or equal to #getMaxCFSSegmentSizeMB() and the size is less or equal to the TotalIndexSize * #getNoCFSRatio() otherwise false.
