Method Detail
-
evaluate
public boolean evaluate(T o)
Apply the test to the input argument.
-
evaluateEntry
public boolean evaluateEntry(Map.Entry entry)
Apply the test to a Map Entry.- Specified by:
evaluateEntry
in interfaceEntryFilter<Object,T>
- Parameters:
entry
- the Map Entry to evaluate; never null- Returns:
- true if the test passes, false otherwise
-
explain
public void explain(QueryContext ctx, QueryRecord.PartialResult.ExplainStep step, Set setKeys)
Record the projected query execution cost by this filter.This method is expected to record the order of execution and estimated cost of applying corresponding indexes in the given
step
without actually applying any indexes or evaluating entries.- Specified by:
explain
in interfaceQueryRecorderFilter<T>
- Overrides:
explain
in classAbstractQueryRecorderFilter<T>
- Parameters:
ctx
- the query contextstep
- the step used to record the estimated execution costsetKeys
- the set of keys that would be filtered
-
trace
public Filter trace(QueryContext ctx, QueryRecord.PartialResult.TraceStep step, Set setKeys)
Filter the given keys using available indexes and record the cost of execution on the given step of theQueryRecord
.This method should record the size of the given key set before and after applying corresponding indexes using
QueryRecord.PartialResult.RecordableStep.recordPreFilterKeys(int)
andQueryRecord.PartialResult.TraceStep.recordPostFilterKeys(int)
as well as the corresponding execution time using theQueryRecord.PartialResult.TraceStep.recordDuration(long)
method.This method is only called if the filter is an
IndexAwareFilter
and its implementations should explicitly callapplyIndex()
to actually perform the query. Additionally, this method should return the filter object (if any) returned by the applyIndex() call.- Specified by:
trace
in interfaceQueryRecorderFilter<T>
- Overrides:
trace
in classAbstractQueryRecorderFilter<T>
- Parameters:
ctx
- the query contextstep
- the step used to record the execution costsetKeys
- the mutable set of keys that remain to be filtered- Returns:
- the filter returned from
IndexAwareFilter.applyIndex(Map, Set)
-
trace
public boolean trace(QueryContext ctx, QueryRecord.PartialResult.TraceStep step, Map.Entry entry)
Evaluate the specified entry against this filter and record the evaluation cost on the given step of theQueryRecord
.This method should record the corresponding latencies using
QueryRecord.PartialResult.TraceStep.recordDuration(long)
.Implementations are responsible for explicitly calling
evaluateEntry()
method to perform the actual entry evaluation. Additionally, this method should return the result of the evaluateEntry call.- Specified by:
trace
in interfaceQueryRecorderFilter<T>
- Overrides:
trace
in classAbstractQueryRecorderFilter<T>
- Parameters:
ctx
- the contextstep
- the step used to record the evaluation costentry
- the entry to evaluate- Returns:
- the result returned from
EntryFilter.evaluateEntry(Map.Entry)
