DESCRIPTION

33       This module provides a simple counter attribute, which can be
34       incremented and decremented by arbitrary amounts.  The default amount
35       of change is one.
36

PROVIDED METHODS

38       These methods are implemented in
39       Moose::Meta::Attribute::Native::MethodProvider::Counter. It is
40       important to note that all those methods do in place modification of
41       the value stored in the attribute.
42
43       set($value)
44           Set the counter to the specified value.
45
46       inc($arg)
47           Increase the attribute value by the amount of the argument.  No
48           argument increments the value by 1.
49
50       dec($arg)
51           Decrease the attribute value by the amount of the argument.  No
52           argument decrements the value by 1.
53
54       reset
55           Resets the value stored in this slot to it's default value.
