public interface Diff extends EObject
A representation of the model object 'Diff'. A DiffElement describes a difference related to the EObjects mapped by its parent MatchElement.

The following features are supported:

    • getMatch

      Match getMatch()
      Returns the value of the 'Match' container reference. It is bidirectional and its opposite is 'Differences'. Back-reference towards this difference's parent match, it points towards the mapping on which this difference has been detected.
      Returns:
      the value of the 'Match' container reference.

    • setMatch

      void setMatch(Match value)
      Sets the value of the 'Match' reference.
      Parameters:
      value - the new value of the 'Match' reference.

    • getRequires

      EList<Diff> getRequires()
      Returns the value of the 'Requires' reference list. The list contents are of type Diff. It is bidirectional and its opposite is ' Required By'. This will reference all differences that should be merged before this one.
      Returns:
      the value of the 'Requires' reference list.
      See Also:

    • getRequiredBy

      EList<Diff> getRequiredBy()
      Returns the value of the 'Required By' reference list. The list contents are of type Diff. It is bidirectional and its opposite is ' Requires'. This will reference all differences that depend on this one for their merging.
      Returns:
      the value of the 'Required By' reference list.

    • getImplies

      EList<Diff> getImplies()
      Returns the value of the 'Implies' reference list. The list contents are of type Diff. It is bidirectional and its opposite is 'Implied By'.

      If the meaning of the 'Implies' reference list isn't clear, there really should be more of a description here...

      Returns:
      the value of the 'Implies' reference list.

    • getImpliedBy

      EList<Diff> getImpliedBy()
      Returns the value of the 'Implied By' reference list. The list contents are of type Diff. It is bidirectional and its opposite is 'Implies'.

      If the meaning of the 'Implied By' reference list isn't clear, there really should be more of a description here...

      Returns:
      the value of the 'Implied By' reference list.

    • getRefines

      EList<Diff> getRefines()
      Returns the value of the 'Refines' reference list. The list contents are of type Diff. It is bidirectional and its opposite is ' Refined By'. This can be used to create "high level" differences to regroup one or more diffs in a common "container". For example, this could be used to regroup n technical differences into one single semantic difference, such as the differences "profile application added" and "reference to stereotype added" that can actually be regrouped under a single, more understandable "stereotype application added".
      Returns:
      the value of the 'Refines' reference list.

    • getRefinedBy

      EList<Diff> getRefinedBy()
      Returns the value of the 'Refined By' reference list. The list contents are of type Diff. It is bidirectional and its opposite is ' Refines'. This will reference the higher-level difference that shadows this one, if any.
      Returns:
      the value of the 'Refined By' reference list.

    • getPrimeRefining

      Diff getPrimeRefining()
      Returns the value of the 'Prime Refining' reference.

      If the meaning of the 'Prime Refining' reference isn't clear, there really should be more of a description here...

      Returns:
      the value of the 'Prime Refining' reference.

    • getKind

      DifferenceKind getKind()
      Returns the value of the 'Kind' attribute. The literals are from the enumeration DifferenceKind. Describes the kind of this difference, whether it is an addition, deletion, change, or move.
      Returns:
      the value of the 'Kind' attribute.

    • setKind

      void setKind(DifferenceKind value)

    • getConflict

      Conflict getConflict()
      Returns the value of the 'Conflict' reference. It is bidirectional and its opposite is 'Differences'. If this element is in conflict with one (or more) other differences, this will reference the Conflict association.
      Returns:
      the value of the 'Conflict' reference.

    • setConflict

      void setConflict(Conflict value)

    • getSource

      DifferenceSource getSource()
      Returns the value of the 'Source' attribute. The literals are from the enumeration DifferenceSource. Returns the source of this diff, either one of DifferenceSource.LEFT (for two-way comparisons or differences detected between the left and origin elements) or DifferenceSource.RIGHT (for differences between the right and origin elements).
      Returns:
      the value of the 'Source' attribute.

    • setSource

      void setSource(DifferenceSource value)

    • getState

      DifferenceState getState()
      Returns the value of the 'State' attribute. The literals are from the enumeration DifferenceState. Returns the current state of this diff, either one of DifferenceState.UNRESOLVED (Diff is still in its initial state), DifferenceState.MERGED when the Diff has been merged or DifferenceState.DISCARDED if the user chose to ignore this difference.
      Returns:
      the value of the 'State' attribute.

    • setState

      void setState(DifferenceState value)

    • getEquivalence

      Equivalence getEquivalence()
      Returns the value of the 'Equivalence' reference. It is bidirectional and its opposite is 'Differences'. If this diff is equivalent to another, we will reference the equivalence from here. For example, if a reference has an eOpposite, we will detect one diff for each side of the bidirectional reference, yet merging one of these diffs is enough. We consider them equivalent.
      Returns:
      the value of the 'Equivalence' reference.

    • setEquivalence

      void setEquivalence(Equivalence value)
      Sets the value of the 'Equivalence' reference.
      Parameters:
      value - the new value of the 'Equivalence' reference.

    • discard

      void discard()
      This will remove the diff from the model, effectively "forgetting" about it.
