Documentation

Overview

Package resolver provides interface and default implementation of resolvers for getting objects from references. Interface Resolver uses interface{} type for reference, class and proxy (which GetObject returns), because in future implementation its going to be plugin. Virtual machine will be use it and provide resolving logic.

Usage:

package main

import (
	"github.com/insolar/insolar/genesis/model/class"
	"github.com/insolar/insolar/genesis/model/object"
}

func main() {
	resolver := NewChildResolver(parent)
	obj, err := resolver.GetObject(ref, class.ObjectID)
	res := obj.(object.Object)
}

Proxy provides interface and default implementation of proxy. It inherited by SmartContractProxy and Factory

Usage:

proxy.SetReference(Reference) sets reference to proxy.
proxy.GetReference() gets reference from proxy.
proxy.GetParent() always returns nil.
proxy.GetClassID() is a proxy call for instance method.

ReferenceContainer provides methods for store Reference as Proxy

Usage:

ref, _ := object.NewReference(domain, record, object.GlobalScope)
container = NewReferenceContainer(ref)

container.GetClassID()         // return string representation of object's class.
container.GetStoredReference() // returns stored reference.

Variables

var GlobalResolver = newGlobalResolver()

GlobalResolver is a public globalResolver instance for resolving all global references.

Types

type BaseProxy

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

BaseProxy is a base implementation of Proxy.

func (*BaseProxy) GetClassID

func (bp *BaseProxy) GetClassID() string

GetClassID is a proxy call for instance method.

func (*BaseProxy) GetParent

func (bp *BaseProxy) GetParent() object.Parent

GetParent always returns nil.

func (*BaseProxy) GetReference

func (bp *BaseProxy) GetReference() object.Reference

GetReference is a proxy call for instance method.

func (*BaseProxy) SetReference

func (bp *BaseProxy) SetReference(reference object.Reference)

SetReference is a proxy call for instance method.

type Handler

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

Handler should resolve references from any allowed scopes.

func NewHandler

func NewHandler(p interface{}) *Handler

NewHandler creates new resolverHandler instance.

func (*Handler) GetObject

func (r *Handler) GetObject(reference interface{}, classID interface{}) (interface{}, error)

GetObject resolves object by its reference and return its proxy.

func (*Handler) InitGlobalMap

func (r *Handler) InitGlobalMap(globalInstanceMap *map[string]Proxy)

InitGlobalMap sets globalInstanceMap into globalResolver.

type Proxy

type Proxy interface {
	object.Child
	GetReference() object.Reference
	SetReference(reference object.Reference)
}

Proxy marks instance as proxy object.

type ReferenceContainer

type ReferenceContainer struct {
	BaseProxy
	// contains filtered or unexported fields
}

ReferenceContainer is a implementation of Proxy for containerization purpose.

func NewReferenceContainer

func NewReferenceContainer(ref object.Reference) *ReferenceContainer

NewReferenceContainer creates new container for reference.

func (*ReferenceContainer) GetClassID

func (rc *ReferenceContainer) GetClassID() string

GetClassID return string representation of object's class.

func (*ReferenceContainer) GetStoredReference

func (rc *ReferenceContainer) GetStoredReference() object.Reference

GetStoredReference returns stored reference.

type Resolver

type Resolver interface {
	GetObject(reference interface{}, classID interface{}) (interface{}, error)
}

Resolver marks that instance have ability to get proxy objects by its reference.
