type Querier 

type Querier struct {
	Keeper
}

Querier is used as Keeper will have duplicate methods if used directly, and gRPC names take precedence over keeper

func (Querier) Account 

func (q Querier) Account(c context.Context, request *types.QueryAccountRequest) (*acm.Account, error)

type State 

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

State is the CVM state object. It implements acmstate.ReaderWriter.

func (*State) GetAccount 

func (s *State) GetAccount(address crypto.Address) (*acm.Account, error)

GetAccount gets an account by its address and returns nil if it does not exist (which should not be an error).

func (*State) GetAddressMeta 

func (s *State) GetAddressMeta(address crypto.Address) ([]*acm.ContractMeta, error)

GetAddressMeta returns the metadata hash of an address

func (*State) GetMetadata 

func (s *State) GetMetadata(metahash acmstate.MetadataHash) (string, error)

GetMetadata returns the metadata of the cvm module.

func (*State) GetStorage 

func (s *State) GetStorage(address crypto.Address, key binary.Word256) (value []byte, err error)

GetStorage retrieves a 32-byte value stored at the key for the account at the address and returns Zero256 if the key does not exist or if the address does not exist.

Note: burrow/acm/acmstate.StorageGetter claims that an error should be thrown upon non-existing address. However, when being embedded in acmstate.Cache, which is the case here, we cannot do that because the contract creation code might load from the new contract's storage, while the cache layer caches the account creation action hence the embedded storage getter will not be aware of it. Returning error in this case would fail the contract deployment.

func (*State) RemoveAccount 

func (s *State) RemoveAccount(address crypto.Address) error

RemoveAccount removes the account at the address.

func (*State) SetAddressMeta 

func (s *State) SetAddressMeta(address crypto.Address, contMeta []*acm.ContractMeta) error

SetAddressMeta sets the metadata hash for an address

func (*State) SetMetadata 

func (s *State) SetMetadata(metahash acmstate.MetadataHash, metadata string) error

SetMetadata sets the metadata of the cvm module.

func (*State) SetStorage 

func (s *State) SetStorage(address crypto.Address, key binary.Word256, value []byte) error

SetStorage stores a 32-byte value at the key for the account at the address. Setting to Zero256 removes the key.

func (*State) UpdateAccount 

func (s *State) UpdateAccount(updatedAccount *acm.Account) error

UpdateAccount updates the fields of updatedAccount by address, creating the account if it does not exist.
