Types

type Client

type Client struct {
	ChainID uint64
	// contains filtered or unexported fields
}

Client implements the ClientInterf that reads data from the Ethereum blockchain

func New

func New(opts Options) (*Client, error)

New loads a new Client

func (*Client) Sync

func (c *Client) Sync() error

Sync synchronizes the blocknums and events since the last synced block to the current one, and then live syncs the new ones

type ClientInterf

type ClientInterf interface {
	// Sync scans the contract activity since the given fromBlock until the
	// current block, storing in the database all the updates on the
	// Processess
	Start(fromBlock uint64) error
}

ClientInterf defines the interface that synchronizes with the Ethereum blockchain to obtain the processes data

type Options

type Options struct {
	EthURL       string
	SQLite       *db.SQLite
	ContractAddr common.Address
}

Options is used to pass the parameters to load a new Client

type TestEthClient

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

TestEthClient simulates an EthReader for testing purposes

func NewTestEthClient

func NewTestEthClient(sqlite *db.SQLite, startBlock uint64,
	blocks map[uint64][]TestEvent) *TestEthClient

NewTestEthClient returns a new TestEthClient with the given configuration

func (*TestEthClient) AdvanceBlock

func (e *TestEthClient) AdvanceBlock() error

AdvanceBlock simulates the advance of the EthBlockNum in the TestEthClient

func (*TestEthClient) Start

func (e *TestEthClient) Start(fromBlock uint64) error

Start implements the EthReader.Start method of the interface

type TestEvent

type TestEvent types.Process

TestEvent is used to simulate creation of new processes in the SmartContract
