Example 1 with MethodDeclaration

use of org.eclipse.n4js.n4JS.MethodDeclaration in project n4js by eclipse.

the class N4JSMemberRedefinitionValidator method unusedGenericTypeVariable.

                // type variable in the method declaration, and the type variable in the type model is not identical
                // to the one in the AST which we actually need.
