ValidatorExported is designed for Validator export

func (ValidatorExported) ConsAddress 

func (ve ValidatorExported) ConsAddress() sdk.ConsAddress

ConsAddress returns the TM validator address of exported validator

func (ValidatorExported) Import 

func (ve ValidatorExported) Import() Validator

Import converts validator exported format to inner one by filling the zero-value of Tokens and Commission

func (ValidatorExported) IsBonded 

func (ve ValidatorExported) IsBonded() bool

IsBonded checks if the exported validator status equals Bonded

type ValidatorSet 

type ValidatorSet interface {
	// iterate through validators by operator address, execute func for each validator
	IterateValidators(sdk.Context,
		func(index int64, validator stakingexported.ValidatorI) (stop bool))

	// iterate through bonded validators by operator address, execute func for each validator
	IterateBondedValidatorsByPower(sdk.Context,
		func(index int64, validator stakingexported.ValidatorI) (stop bool))

	// iterate through the consensus validator set of the last block by operator address, execute func for each validator
	IterateLastValidators(sdk.Context,
		func(index int64, validator stakingexported.ValidatorI) (stop bool))
	// get a particular validator by operator address
	Validator(sdk.Context, sdk.ValAddress) stakingexported.ValidatorI
	// get a particular validator by consensus address
	ValidatorByConsAddr(sdk.Context, sdk.ConsAddress) stakingexported.ValidatorI
	// total bonded tokens within the validator set
	TotalBondedTokens(sdk.Context) sdk.Dec
	// total staking token supply
	StakingTokenSupply(sdk.Context) sdk.Dec

	// slash the validator and delegators of the validator, specifying offence height, offence power, and slash fraction
	// jail a validator
	Jail(sdk.Context, sdk.ConsAddress)
	// unjail a validator
	Unjail(sdk.Context, sdk.ConsAddress)

	// MaxValidators returns the maximum amount of bonded validators
	MaxValidators(sdk.Context) uint16
}

ValidatorSet expected properties for the set of all validators (noalias)
