    type CheckpointOracle

    type CheckpointOracle struct {
    	// contains filtered or unexported fields

      CheckpointOracle is a Go wrapper around an on-chain checkpoint oracle contract.

      func NewCheckpointOracle

      func NewCheckpointOracle(contractAddr common.Address, backend bind.ContractBackend) (*CheckpointOracle, error)

        NewCheckpointOracle binds checkpoint contract and returns a registrar instance.

        func (*CheckpointOracle) Contract

        func (oracle *CheckpointOracle) Contract() *contract.CheckpointOracle

          Contract returns the underlying contract instance.

          func (*CheckpointOracle) ContractAddr

          func (oracle *CheckpointOracle) ContractAddr() common.Address

            ContractAddr returns the address of contract.

            func (*CheckpointOracle) LookupCheckpointEvents

            func (oracle *CheckpointOracle) LookupCheckpointEvents(blockLogs [][]*types.Log, section uint64, hash common.Hash) []*contract.CheckpointOracleNewCheckpointVote

              LookupCheckpointEvents searches checkpoint event for specific section in the given log batches.

              func (*CheckpointOracle) RegisterCheckpoint

              func (oracle *CheckpointOracle) RegisterCheckpoint(opts *bind.TransactOpts, index uint64, hash []byte, rnum *big.Int, rhash [32]byte, sigs [][]byte) (*types.Transaction, error)

                RegisterCheckpoint registers the checkpoint with a batch of associated signatures that are collected off-chain and sorted by lexicographical order.

                Notably all signatures given should be transformed to "ethereum style" which transforms v from 0/1 to 27/28 according to the yellow paper.
