Types

type Activation

type Activation hamt.Map

func NewActivation

func NewActivation() Activation

func (Activation) Find

func (a Activation) Find(name string) interface{}

func (Activation) FirstRest

func (a Activation) FirstRest() (string, interface{}, Activation)

func (Activation) ForEach

func (a Activation) ForEach(cb func(string, interface{}) error) error

func (Activation) Insert

func (a Activation) Insert(name string, value interface{}) Activation

type Activations

type Activations struct {
	// contains filtered or unexported fields
}

Activations is a stack of activation records. Each entry represents a new scope.

func (*Activations) CurrentOrNew

func (a *Activations) CurrentOrNew() Activation

func (*Activations) Depth

func (a *Activations) Depth() int

func (*Activations) Find

func (a *Activations) Find(key string) interface{}

func (*Activations) Pop

func (a *Activations) Pop()

func (*Activations) Push

func (a *Activations) Push(activation Activation)

func (*Activations) PushCurrent

func (a *Activations) PushCurrent()

PushCurrent makes a copy of the current activation, and pushes it to the top of the activation stack, so that the `Find` method only needs to look up a certain record by name from the current activation record without having to go through each activation in the stack.

func (*Activations) Set

func (a *Activations) Set(name string, value interface{})

Set adds the new key value pair to the current scope. The current scope is updated in an immutable way.
