Method Detail

truncate

public TimeRange truncate(Date candidateStartTime,
                          Date candidateEndTime)

isCoverableBy

public boolean isCoverableBy(Set<UpdatePeriod> updatePeriods)

truncate

public TimeRange truncate(UpdatePeriod updatePeriod)
                   throws LensException

Truncate time range using the update period. The lower value of the truncated time range is the smallest date value equal to or larger than original time range's lower value which lies at the update period's boundary. Similarly for higher value.

Parameters:

updatePeriod - Update period to truncate time range with

Returns:

truncated time range

Throws:

LensException - If the truncated time range is invalid.

milliseconds

public long milliseconds()

cloneAsBuilder

public TimeRange.TimeRangeBuilder cloneAsBuilder()

isValid

public boolean isValid()

validate

public void validate()
              throws LensException

Throws:

LensException

toTimeDimWhereClause

public String toTimeDimWhereClause(String prefix,
                                   String column)

toString

public String toString()

Overrides:
