Pair

type Interface ¶

type Interface interface {
	First() interface{}
	Second() interface{}
	Equal(Interface) bool
	ToArray() Array.Interface
	ToGoString() string
	IsNull() bool
}

Interface is the fixed two-element heterogeneous grouping: the natural key/value entry of Composition-Oriented Programming. A Pair never goes nil; the Null-Object variant honours the whole Interface.
