    Method method = methodExecutor.getMethod();
    boolean isStaticMethod = Modifier.isStatic(method.getModifiers());
    String descriptor = cf.lastDescriptor();

Example 3 with ReflectiveMethodExecutor

use of org.springframework.expression.spel.support.ReflectiveMethodExecutor in project spring-framework by spring-projects.

the class MethodReference method isCompilable.
