Types

type Any

type Any = interface{}

Any represents a object that may contain any valid type.

type AnyValue

type AnyValue interface {

	// ValueOf returns a new Value initialized to the
	// concrete value stored in the interface i.
	// ValueOf(nil) returns the zero Value.
	ValueOf() reflect.Value

	// TypeOf returns the object's type.
	TypeOf() reflect.Type

	// Kind returns v's Kind. If v is the zero Value
	// (IsValid returns false), Kind returns Invalid.
	Kind() reflect.Kind

	// Interface returns the original underlying interface.
	Interface() Any

	// Indirect returns the value pointed to by a pointer.
	// If the AnyValue is not a pointer, indirect returns the
	// AnyValue unchanged.
	Indirect() AnyValue

	// Elem returns the value that the interface contains
	// or that the pointer points to. If the kind of the
	// AnyValue is not Interface or Ptr, the original
	// AnyValue is returned.
	Elem() reflect.Value

	String() string

	KindInfo
}

AnyValue is a wrapper around the Any interface, or interface{}, which may contain any value. The extra features of this wrapper allow value, type, and kind information, as well as whether the type is comparable, ordered, and/or iterable.

func NewAnyValue

func NewAnyValue(a Any) AnyValue

NewAnyValue returns a new AnyValue interface, e.g. v := NewAnyValue(uint(42))

AnyValue is a wrapper around the Any interface, or interface{}, which may contain any value. The original interface{} value is returned by v.Interface()

The extra features of this wrapper allow value, type, and kind information, as well as whether the type is comparable, ordered, and/or iterable.

type Kind

type Kind = reflect.Kind

A Kind represents the specific kind of type that a Type represents. The zero Kind is not a valid kind.
