ch.uzh.ifi.seal.changedistiller.model.entities.SourceCodeChange
General (abstract) representation of a source code change.
Each source code change has a
- {@link StructureEntityVersion} rootEntity that describes in which attribute, class, or method thechanges was made. The rootEntity is taken from the right AST, i.e., new version of the {@link StructureEntityVersion}.
- {@link SourceCodeEntity} changedEntity that describes which source code entity has changed. In caseof
  - {@link Delete}: the entity that was deleted; it is taken from the left AST, i.e., old version.
  - {@link Insert}: the entity that was inserted; it is taken from the right AST, i.e., new version.
  - {@link Move}: the entity that was moved; it is taken from the left AST, i.e., old version.
  - {@link Update}: the entity that was updated; it is taken from the left AST, i.e., old version.
Other entities involved in a source code change are described in the corresponding concrete implementation. @author Beat Fluri @author Giacomo Ghezzi @author zubi @see Delete @see Insert @see Move @see Update
