All Implemented Interfaces:
Predicate<VariationNode<?,?>>, Source, Relevance
public record Trace(String featureName) extends Record implements Relevance
Relevance predicate that traces a certain feature syntactically within a variation tree. This relevance predicate is the implementation of Equation 6 in our SPLC'23 paper.

  • Field Details

    • featureName

      private final String featureName
      The field for the featureName record component.

  • Constructor Details

    • Trace

      public Trace(String featureName)
      Creates an instance of a Trace record class.
      Parameters:
      featureName - the value for the featureName record component

  • Method Details

    • test

      public boolean test(VariationNode<?,?> v)
      Specified by:
      test in interface Predicate<VariationNode<?,?>>

    • getSourceArguments

      public List<Object> getSourceArguments()
      Description copied from interface: Source
      Returns a list of arguments required to understand this source. Each argument in the result list should represent a string without newlines and will be formatted together with Source.getSourceExplanation() like "sourceExplanation(argument1, argument2)" by Source.shallowExplanation(). This method is only intended to access the arguments for printing. In case access to the well-typed object is required, use Source.<T>findFirst(org.variantsync.diffdetective.util.Source,java.lang.Class<T>) or Source.<T>findAll(org.variantsync.diffdetective.util.Source,java.lang.Class<T>) and use the accessors of the underlying type.

      For ease of implementing Source, the return value is a list of Objects instead of a list of Strings to allow code like List.of(arg0, arg1, arg2) instead of List.of(arg0.toString(), arg1.toString(), arg2.toString()). Users of this function should assume nothing from the returned objects except that Object.toString() is well behaved.

      Specified by:
      getSourceArguments in interface Source
      Returns:
      an empty list by default
      See Also:

    • getSourceExplanation

      public String getSourceExplanation()
      Description copied from interface: Source
      Returns a short, one line explanation or identifier of this source. The result is used by Source.shallowExplanation() and is formatted together with Source.getSourceArguments() like "sourceExplanation(argument1, argument2)".
      Specified by:
      getSourceExplanation in interface Source

    • toString

      public String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • featureName

      public String featureName()
      Returns the value of the featureName record component.
      Returns:
      the value of the featureName record component
