Example 41 with ObjectCreationExpr

use of com.github.javaparser.ast.expr.ObjectCreationExpr in project checker-framework by typetools.

the class JointJavacJavaParserVisitor method visitNewClass.

    // MyInnerClass() would store "this" as the enclosing expression. In Java 8, this would be
    // stored as new MyInnerClass(this). So, for the argument lists to match, we may have to
    // remove the first argument.
