Examples of org.teavm.model.MethodReference

org.teavm.model.MethodReference

Specifies a fully qualified name of a method, including its name, class name, parameter types and return value type. This class overloads equals and hashCode so that any two references to one method are considered equal.

Though in Java language it is enough to have only parameter types to uniquely identify a method, JVM uses return value as well. Java generates bridge methods to make adjust the JVM's behavior.
