Class PropertyComparison

java.lang.Object
  eu.planets_project.services.compare.PropertyComparison

public final class PropertyComparison
extends Object

This class encapsulates a comparison property. That is, it encapsulates a single property related to the comparison of the content of two digital objects. The 'first' and 'second' objects. In the 'significant property' case, this is the comparison of the values of a particular property that has been extracted from both files. More generally, this may be a property that encapsulates the relationship between different subsets of properties from each object. i.e. when the same concept is encoded differently in each. Finally, this can be a direct comparison property, like Peak Signal-to-Noise Ratio. These are not a simple comparisons of the properties of objects, but direct expression of the differences between the content or the expected performances.
