Constructor Detail

ExplainStep

public ExplainStep(Filter filter)

Construct an ExplainStep

Parameters:

filter - the step filter

Method Detail

recordEfficiency

public void recordEfficiency(int nEfficiency)

Record the calculated cost of applying the filter as defined by calculateEffectiveness

Specified by:

recordEfficiency in interface QueryRecord.PartialResult.ExplainStep

Parameters:

nEfficiency - an effectiveness estimate of how well the associated filter can use any applicable index

ensureStep

public QueryRecord.PartialResult.ExplainStep ensureStep(Filter filter)

Ensure an inner nested explain step for the given filter. If there is no inner nested step associated with the given filter then a new step is created.

Specified by:

ensureStep in interface QueryRecord.PartialResult.ExplainStep

Parameters:

filter - the filter to associate the new step with

Returns:

the inner nested step associated with the given filter
