Method Detail

canCompare

public boolean canCompare(IModel m1,
                          IModel m2)

Description copied from interface: IModelComparator

Checks if the comparator can compare these two models.

Specified by:

canCompare in interface IModelComparator

Returns:

true if IModelComparator.compare(IModel, IModel) should finish successfully, and false otherwise.

compare

public java.lang.Object compare(IModel m1,
                                IModel m2)
                         throws java.lang.Exception

Description copied from interface: IModelComparator

Returns an object with the differences between this model and otherModel. If there are no differences, returns null. The exact configuration of the comparison depends on the model. For instance, unique identifiers (such as XMI IDs) may be ignored if the main object of these comparisons is to test model transformations. These tend to produce different unique identifiers each time they are run.

Specified by:

compare in interface IModelComparator

Throws:

java.lang.IllegalArgumentException - The models cannot be compared: for instance, they use incompatible drivers.

java.lang.Exception - There was some other kind of problem when performing the comparison.

configure

public void configure(java.util.Map<java.lang.String,java.lang.Object> options)

Description copied from interface: IModelComparator

Configures the model comparator with the specified options.

Specified by:

configure in interface IModelComparator
