Types

type AtomBehaviour

type AtomBehaviour struct {
	Reads     []StateAddress // States read by an atom.
	Modifies  []StateAddress // States read and written by an atom.
	Writes    []StateAddress // States written by an atom.
	Roots     []StateAddress // States labeled as root by an atom.
	KeepAlive bool           // Force the atom to be live.
	Aborted   bool           // Mutation of this command aborts.
}

func (*AtomBehaviour) Modify

func (b *AtomBehaviour) Modify(g *DependencyGraph, state StateKey)

func (*AtomBehaviour) Read

func (b *AtomBehaviour) Read(g *DependencyGraph, state StateKey)

func (*AtomBehaviour) Write

func (b *AtomBehaviour) Write(g *DependencyGraph, state StateKey)

type BehaviourProvider

type BehaviourProvider interface {
	GetBehaviourForAtom(context.Context, *api.State, api.CmdID, api.Cmd, *DependencyGraph) AtomBehaviour
}

type DependencyGraph

type DependencyGraph struct {
	Commands   []api.Cmd             // Atom list which this graph was build for.
	Behaviours []AtomBehaviour       // State reads/writes for each atom (graph edges).
	Roots      map[StateAddress]bool // State to mark live at requested atoms.
	// contains filtered or unexported fields
}

func GetDependencyGraph

func GetDependencyGraph(ctx context.Context) (*DependencyGraph, error)

func (*DependencyGraph) GetHierarchyStateMap

func (g *DependencyGraph) GetHierarchyStateMap() map[StateAddress]StateAddress

func (*DependencyGraph) GetStateAddressOf

func (g *DependencyGraph) GetStateAddressOf(key StateKey) StateAddress

func (*DependencyGraph) Print

func (g *DependencyGraph) Print(ctx context.Context, b *AtomBehaviour)

func (*DependencyGraph) SetRoot

func (g *DependencyGraph) SetRoot(key StateKey)

type DependencyGraphBehaviourProvider

type DependencyGraphBehaviourProvider interface {
	GetDependencyGraphBehaviourProvider(ctx context.Context) BehaviourProvider
}

type StateAddress

type StateAddress uint32

type StateKey

type StateKey interface {
	// Parent returns enclosing state (and this state is strict subset of it).
	// This allows efficient implementation of operations which access a lot state.
	Parent() StateKey
}

State key uniquely represents part of the GL state. Think of it as memory range (which stores the state data).
