This method returns true only if the parameter's default value is set to a named constant. e.g.
class Foo {
const OPTION_MULTIGET = 1;
//Method 1
public function setGetOptions($opts=0);
//Method 2
public function setMultiGetOptions($opts=Foo::OPTION_MULTIGET);
}
Method 1's first ReflectionParameter will return isDefaultValueConstant() = false (0 is a "constant"/static value but not a named constant) and Method 2's will return isDefaultValueConsntant() = true.
