Block interface exposed to QML

func NewBlock

func NewBlock(block *types.Block) *Block

Creates a new QML Block from a chain block

func (*Block) GetTransaction

func (self *Block) GetTransaction(hash string) *Transaction

func (*Block) ToString

func (self *Block) ToString() string

type Frontend

type Frontend interface {
	// UnlockAccount is called when a transaction needs to be signed
	// but the key corresponding to the transaction's sender is
	// locked.
	//
	// It should unlock the account with the given address and return
	// true if unlocking succeeded.
	UnlockAccount(address []byte) bool

	// This is called for all transactions inititated through
	// Transact. It should prompt the user to confirm the transaction
	// and return true if the transaction was acknowledged.
	//
	// ConfirmTransaction is not used for Call transactions
	// because they cannot change any state.

}

Frontend should be implemented by users of XEth. Its methods are called whenever XEth makes a decision that requires user input.
