Class TimeRange

java.lang.Object

org.apache.hadoop.hbase.io.TimeRange

@InterfaceAudience.Public
@InterfaceStability.Stable
public class TimeRange
extends Object

Represents an interval of version timestamps.

Evaluated according to minStamp <= timestamp < maxStamp or [minStamp,maxStamp) in interval notation.

Only used internally; should not be accessed directly by clients.

Method Detail

getMin

public long getMin()

Returns:

the smallest timestamp that should be considered

getMax

public long getMax()

Returns:

the biggest timestamp that should be considered

isAllTime

public boolean isAllTime()

Check if it is for all time

Returns:

true if it is for all time

withinTimeRange

public boolean withinTimeRange(byte[] bytes,
                      int offset)

Check if the specified timestamp is within this TimeRange.

Returns true if within interval [minStamp, maxStamp), false if not.

Parameters:

bytes - timestamp to check

offset - offset into the bytes

Returns:

true if within TimeRange, false if not

withinTimeRange

public boolean withinTimeRange(long timestamp)

Check if the specified timestamp is within this TimeRange.

Returns true if within interval [minStamp, maxStamp), false if not.

Parameters:

timestamp - timestamp to check

Returns:

true if within TimeRange, false if not

withinOrAfterTimeRange

public boolean withinOrAfterTimeRange(long timestamp)

Check if the specified timestamp is within this TimeRange.

Returns true if within interval [minStamp, maxStamp), false if not.

Parameters:

timestamp - timestamp to check

Returns:

true if within TimeRange, false if not

compare

public int compare(long timestamp)

Compare the timestamp to timerange

Parameters:

timestamp -

Returns:

-1 if timestamp is less than timerange, 0 if timestamp is within timerange, 1 if timestamp is greater than timerange

toString

public String toString()

Overrides:

toString in class Object
