Class ClassComparer

java.lang.Object

org.eclipse.collections.impl.test.ClassComparer

public class ClassComparer
extends Object

This class will compare the method signatures between two classes. The comparison can be based on the following method information:

• Method Name
• Method Name + Parameter Types
• Method Name + Return Type
• Method Name + Parameter Types + Return Type

The operations that can be used to compare the method signatures of two classes are:

• Intersection
• Difference
• Symmetric difference
• isProperSubsetOf
• isProperSupersetOf
