Deploy

when deploy it is no need to pass parameters in to constructor

Overview

Once installed will be use methods:

method name	called by	description
IntercoinContract.sol
init	owner	initializing after deploy
produceFactory	owner	creating factory possible to create contract instance
registerInstance	only factories created by IntercoinContract	registering contracts created by factories
checkInstance	anyone	checking contracts created by factory
renounceOwnership	owner	Leaves the contract without owner. It will not be possible to call `onlyOwner` functions anymore.
Factory.sol
init	owner	initializing after deploy
produce	anyone	creating contract insance

Methods (IntercoinContract.sol)

init

initializing after deploy

produceFactory

creating factory possible to create contract instance Emitted event ProducedFactory(address addr)
Params:

name	type	description
contractInstance	address	contract's address which need to clone

Return Values:

name	type	description
factoryInstance	address	factory's address

registerInstance

Registering contracts creating by factories Params:

name	type	description
addr	address[]	address of contract instance

Return Values:

name	type	description
success	bool	true if registered successful

checkInstance

checking contracts created by factory Params:

addr	address[]	address of contract instance

Return Values:

name	type	description
success	bool	true if registered successfully before

renounceOwnership

Leaves the contract without owner

Methods (Factory.sol)

init

initializing after deploy

produce

creating factory possible to create contract instance Emitted event Produced(address indexed caller, address indexed addr)
Return Values:

name	type	description
addr	address	contract's address

Lifecycle

1. owner deploy contract which need to be cloned. got contract address
2. owner deploy IntercoinContract and call method init()
3. create factory
   • owner call method produceFactory(<contract address>) at IntercoinContract.
   • emitted event ProducedFactory(<factory address>)
4. creating contract
   • anyone can call method produce() at newly created factory
   • emitted event Produce(<contract address>)
5. now user can call init at newly created contract and would to be owner
