public IncrementalIndexTimeBoundaryInspector(IncrementalIndex index)

Method Details

getMinTime

public org.joda.time.DateTime getMinTime()

Description copied from interface: TimeBoundaryInspector

Lower bound on ColumnHolder.TIME_COLUMN_NAME. Matches the lowest timestamp in the dataset if TimeBoundaryInspector.isMinMaxExact().

Specified by:

getMinTime in interface TimeBoundaryInspector

getMaxTime

public org.joda.time.DateTime getMaxTime()

Description copied from interface: TimeBoundaryInspector

Upper bound on ColumnHolder.TIME_COLUMN_NAME. Strict if TimeBoundaryInspector.isMinMaxExact(). Matches the highest timestamp in the dataset if TimeBoundaryInspector.isMinMaxExact().

Specified by:

getMaxTime in interface TimeBoundaryInspector

isMinMaxExact

public boolean isMinMaxExact()

Description copied from interface: TimeBoundaryInspector

Whether the lower and upper bounds returned by TimeBoundaryInspector.getMinTime() and TimeBoundaryInspector.getMaxTime() are actually found in the dataset. If true, the bounds are strict and can be used substitutes for aggregations MIN(__time) and MAX(__time).

Specified by:

isMinMaxExact in interface TimeBoundaryInspector
