Class IgnoreStrategy<T1 extends JsonValue,T2 extends JsonValue>

java.lang.Object
  de.hpi.fgis.dude.similarityfunction.contentbased.calculationstrategy.IgnoreStrategy<T1,T2>

Type Parameters:

T1 - The type of the first value.

T2 - The type of the second value.

All Implemented Interfaces:

CalculationStrategy<T1,T2>

public class IgnoreStrategy<T1 extends JsonValue,T2 extends JsonValue>
extends Object
implements CalculationStrategy<T1,T2>

IgnoreStrategy ignores the actual values and returns always the same default similarity. The number of times this strategy was used can be reviewed using getCallCount().
