Documentation

Overview

Package contract provides interface and default implementation of smart contract.

Usage:

parent := NewBaseSmartContract(nil)
child := NewBaseSmartContract(parent)

classID := child.GetClassID()

SmartContractProxy is public interface to call object's methods. If you want to make proxy for your object inherit BaseSmartContractProxy

Usage:

// make your custom domain proxy

type customDomainProxy struct {
	object.BaseSmartContractProxy
}

// create proxy for your custom domain

func newCustomDomainProxy(parent object.Parent) (*customDomainProxy, error) {
	instance, err := newCustomDomain(parent)
	if err != nil {
		return nil, err
	}
	return &customDomainProxy{
		BaseSmartContractProxy: object.BaseSmartContractProxy{
			Instance: instance,
		},
	}, nil
}

proxy, err := newCustomDomainProxy(...)

proxy.GetClassID() is a proxy call for instance method.
proxy.GetParent() is a proxy call for instance method.
proxy.GetOrCreateComposite() is a proxy call for instance method if instance inherit ComposingContainer.

Types

type BaseSmartContract

type BaseSmartContract struct {
	object.BaseObject
	CompositeMap   map[string]factory.Composite
	ChildStorage   storage.Storage
	ContextStorage storage.Storage
	Parent         object.Parent
	// contains filtered or unexported fields
}

BaseSmartContract is a base implementation of ComposingContainer, Callable and TypedObject interfaces.

func NewBaseSmartContract

func NewBaseSmartContract(parent object.Parent) *BaseSmartContract

NewBaseSmartContract creates new BaseSmartContract instance with empty CompositeMap, ChildStorage and specific parent.

func (*BaseSmartContract) AddChild

func (sc *BaseSmartContract) AddChild(child object.Child) (string, error)

AddChild add new child to smart contract's ChildStorage.

func (*BaseSmartContract) CreateComposite

func (sc *BaseSmartContract) CreateComposite(compositeFactory factory.CompositeFactory) (factory.Composite, error)

CreateComposite allows to create composites inside smart contract.

func (*BaseSmartContract) GetChild

func (sc *BaseSmartContract) GetChild(key string) (object.Child, error)

GetChild get child from smart contract's ChildStorage.

func (*BaseSmartContract) GetChildStorage

func (sc *BaseSmartContract) GetChildStorage() storage.Storage

GetChildStorage return storage with children of smart contract.

func (*BaseSmartContract) GetClassID

func (sc *BaseSmartContract) GetClassID() string

GetClassID return string representation of object's class.

func (*BaseSmartContract) GetComposite

func (sc *BaseSmartContract) GetComposite(key string) (factory.Composite, error)
