Method Details

totalLength

long totalLength()

dataLength

long dataLength()

dataFillRatio

double dataFillRatio()

isHeadFile

boolean isHeadFile()

hasSingleEntity

boolean hasSingleEntity()

Querying method to check if a storage file consists of only one singular live entity. This is necessary to avoid dissolving files that are oversized because of one single oversized entity.

Returns:

true if the file containts exactely one live entity.
