Klasse VarArgsChecker

java.lang.Object

com.sun.jna.VarArgsChecker

abstract class VarArgsChecker
extends Object

Class for checking if a method has vararg parameters. Use method create() to create an instance of this class. How the returned instance work depends on the capabilities of the underlying JVM implementation. On older versions of the VM not supporting varargs, the returned VarArgsChecker will always return false on calls to isVarArgs(Method).
