Example usage for org.apache.commons.lang3 ClassUtils isAssignable

Introduction

In this page you can find the example usage for org.apache.commons.lang3 ClassUtils isAssignable.

Prototype

public static boolean isAssignable(final Class<?> cls, final Class<?> toClass) 

Source Link

Document

Checks if one Class can be assigned to a variable of another Class .

Unlike the Class#isAssignableFrom(java.lang.Class) method, this method takes into account widenings of primitive classes and null s.

Primitive widenings allow an int to be assigned to a long, float or double.
