Method Details

compareToTimestamp

public int compareToTimestamp(long timestamp)

Description copied from class: CompactionWindow

Compares the window to a timestamp.

Specified by:

compareToTimestamp in class CompactionWindow

Parameters:

timestamp - the timestamp to compare.

Returns:

a negative integer, zero, or a positive integer as the window lies before, covering, or after than the timestamp.

nextEarlierWindow

Description copied from class: CompactionWindow

Move to the new window of the same tier or of the next tier, which represents an earlier time span.

Specified by:

nextEarlierWindow in class CompactionWindow

Returns:

The next earlier window

startMillis

public long startMillis()

Description copied from class: CompactionWindow

Inclusive lower bound

Specified by:

startMillis in class CompactionWindow

endMillis

public long endMillis()

Description copied from class: CompactionWindow

Exclusive upper bound

Specified by:

endMillis in class CompactionWindow
