* <p>Checks if an array of Classes can be assigned to another array of Classes.</p>

|
*
|
||||||
|
* <p>This method calls {@link #isAssignable(Class, Class) isAssignable} for each
|
||||||
|
* Class pair in the input arrays. It can be used to check if a set of arguments
|
||||||
|
* (the first parameter) are suitably compatible with a set of method parameter types
|
||||||
|
* (the second parameter).</p>
|
||||||
|
*
|
||||||
|
* <p>Unlike the {@link Class#isAssignableFrom(java.lang.Class)} method, this
|
||||||
|
* method takes into account widenings of primitive classes and
|
||||||
|
* <code>null</code>s.</p>
|
||||||
|
*
|
||||||
|
* <p>Primitive widenings allow an int to be assigned to a <code>long</code>,
|
||||||
|
* <code>float</code> or <code>double</code>. This method returns the correct
|
||||||
|
* result for these cases.</p>
|
||||||
|
*
|
||||||
|
* <p><code>Null</code> may be assigned to any reference type. This method will
|
||||||
|
* return <code>true</code> if <code>null</code> is passed in and the toClass is
|
||||||
|
* non-primitive.</p>
|
||||||
|
*
|
||||||
|
* <p>Specifically, this method tests whether the type represented by the
|
||||||
|
* specified <code>Class</code> parameter can be converted to the type
|
||||||
|
* represented by this <code>Class</code> object via an identity conversion
|
||||||
|
* widening primitive or widening reference conversion. See
