Class ParameterGroup

java.lang.Object

nl.pim16aap2.util.reflection.ParameterGroup

public class ParameterGroup
extends Object

Represents a group of parameters that describes, for example, the input arguments of a Constructor.

The advantage over using an array of raw Class objects is that these parameters can be marked optional, allowing for greater freedom when searching for a method with a set of parameters.

For example, when providing the types {int.class, boolean.class, float.class} and mark float.class as optional, this set of parameters can be used to match a method void fun(int, boolean) as well as a method void fun(int, boolean, float.

Use ParameterGroup.Builder to create a new instance.
