Constructor Detail

### OffsetFeatureConjunction

    public OffsetFeatureConjunction(java.lang.String thisFeatureName,
                                    java.lang.String[] featureNames,
                                    int[] offsets,
                                    boolean[] isNonNegated,
                                    boolean tagAllTimesteps)

  Create a Pipe for adding conjunctions of specified features.

  Parameters:
    `thisFeatureName` - Name of this conjunction feature.
    `featureNames` - String giving name for each subfeature i.
    `offsets` - For each subfeature i, which offset from the current timestep must i appear at.
    `isNonNegated` - If element i is false, then the negation of the feature is added to the conjuction.
