Method Detail

hasFilters

public boolean hasFilters()

getFilter

public DimFilter getFilter()

getType

public String getType()

getBound

public String getBound()

withOverriddenContext

public TimeBoundaryQuery withOverriddenContext(Map<String,Object> contextOverrides)

withQuerySegmentSpec

public TimeBoundaryQuery withQuerySegmentSpec(QuerySegmentSpec spec)

Description copied from interface: Query

Returns a new query, identical to this one, but with a different associated QuerySegmentSpec. This often changes the behavior of Query.getRunner(QuerySegmentWalker), since most queries inherit that method from BaseQuery, which implements it by calling QuerySegmentSpec.lookup(org.apache.druid.query.Query<T>, org.apache.druid.query.QuerySegmentWalker).

withDataSource

public Query<Result<TimeBoundaryResultValue>> withDataSource(DataSource dataSource)

getCacheKey

public byte[] getCacheKey()

buildResult

public Iterable<Result<TimeBoundaryResultValue>> buildResult(org.joda.time.DateTime timestamp,
                                                             org.joda.time.DateTime min,
                                                             org.joda.time.DateTime max)

mergeResults

public Iterable<Result<TimeBoundaryResultValue>> mergeResults(List<Result<TimeBoundaryResultValue>> results)

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class BaseQuery<Result<TimeBoundaryResultValue>>

hashCode
