Types

type Blocker

type Blocker interface {
	Header

	// GetBlockHeader returns block header
	GetBlockHeader() Header

	// GetTransaction returns transactions in the block
	GetTransaction() []Transactioner

	// GetExtraData returns extra data in the block
	GetExtraData() interface{}
}

Blocker defines the interface that the block needs to implement

type Header

type Header interface {
	// GetChainId returns chainId
	GetChainId() string

	// GetPreHash returns the hash value of previous block
	GetPreHash() []byte

	// GetTxRoot returns the root hash of transaction tree
	GetTxRoot() []byte

	// GetHeight returns block height
	GetHeight() uint64

	// GetBlockHash returns block hash
	GetBlockHash() []byte
}

Header defines the interface that the block header needs to implement

type Transactioner

type Transactioner interface {
	// GetStatusCode returns the transaction status code
	GetStatusCode() int32

	// GetTransactionHash returns transaction hash
	GetTransactionHash() ([]byte, error)

	// GetContractName returns the contract name of transaction
	GetContractName() (string, error)

	// GetMethod returns the method in contract method of transaction
	GetMethod() (string, error)

	// GetParams returns parameters of transaction
	GetParams() ([]interface{}, error)

	// GetExtraData returns extra data of transaction, for example read-write set.
	GetExtraData() (interface{}, error)
}

Transactioner defines the interface that the transaction needs to implement
