Types

type ApplicationProvider

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

ApplicationProvider provides capabilities information for application level config.

func NewApplicationProvider

func NewApplicationProvider(capabilities map[string]*cb.Capability) *ApplicationProvider

NewApplicationProvider creates a application capabilities provider.

func (*ApplicationProvider) ACLs

func (ap *ApplicationProvider) ACLs() bool

ACLs returns whether ACLs may be specified in the channel application config

func (ApplicationProvider) CollectionUpgrade

func (ap ApplicationProvider) CollectionUpgrade() bool

CollectionUpgrade returns true if this channel is configured to allow updates to existing collection or add new collections through chaincode upgrade (as introduced in v1.2)

func (*ApplicationProvider) FabToken

func (ap *ApplicationProvider) FabToken() bool

There is no fabtoken support in v1.4, so always return false

func (*ApplicationProvider) ForbidDuplicateTXIdInBlock

func (ap *ApplicationProvider) ForbidDuplicateTXIdInBlock() bool

ForbidDuplicateTXIdInBlock specifies whether two transactions with the same TXId are permitted in the same block or whether we mark the second one as TxValidationCode_DUPLICATE_TXID

func (*ApplicationProvider) HasCapability

func (ap *ApplicationProvider) HasCapability(capability string) bool

HasCapability returns true if the capability is supported by this binary.

func (*ApplicationProvider) KeyLevelEndorsement

func (ap *ApplicationProvider) KeyLevelEndorsement() bool

KeyLevelEndorsement returns true if this channel supports endorsement policies expressible at a ledger key granularity, as described in FAB-8812

func (*ApplicationProvider) MetadataLifecycle

func (ap *ApplicationProvider) MetadataLifecycle() bool

MetadataLifecycle indicates whether the peer should use the deprecated and problematic v1.0/v1.1/v1.2 lifecycle, or whether it should use the newer per channel peer local chaincode metadata package approach planned for release with Fabric v1.3

func (*ApplicationProvider) PrivateChannelData

func (ap *ApplicationProvider) PrivateChannelData() bool

PrivateChannelData returns true if support for private channel data (a.k.a. collections) is enabled. In v1.1, the private channel data is experimental and has to be enabled explicitly. In v1.2, the private channel data is enabled by default.

func (ApplicationProvider) Supported

func (r ApplicationProvider) Supported() error

Supported checks that all of the required capabilities are supported by this binary.

func (*ApplicationProvider) Type

func (ap *ApplicationProvider) Type() string

Type returns a descriptive string for logging purposes.

func (*ApplicationProvider) V1_1Validation

func (ap *ApplicationProvider) V1_1Validation() bool

V1_1Validation returns true is this channel is configured to perform stricter validation of transactions (as introduced in v1.1).

func (*ApplicationProvider) V1_2Validation

func (ap *ApplicationProvider) V1_2Validation() bool

V1_2Validation returns true if this channel is configured to perform stricter validation of transactions (as introduced in v1.2).

func (*ApplicationProvider) V1_3Validation

func (ap *ApplicationProvider) V1_3Validation() bool

V1_3Validation returns true if this channel is configured to perform stricter validation of transactions (as introduced in v1.3).

type ChannelProvider

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

ChannelProvider provides capabilities information for channel level config.

func NewChannelProvider

func NewChannelProvider(capabilities map[string]*cb.Capability) *ChannelProvider

NewChannelProvider creates a channel capabilities provider.

func (*ChannelProvider) HasCapability

func (cp *ChannelProvider) HasCapability(capability string) bool

HasCapability returns true if the capability is supported by this binary.

func (*ChannelProvider) MSPVersion

func (cp *ChannelProvider) MSPVersion() msp.MSPVersion

MSPVersion returns the level of MSP support required by this channel.

func (ChannelProvider) Supported

func (r ChannelProvider) Supported() error

Supported checks that all of the required capabilities are supported by this binary.

func (*ChannelProvider) Type

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

OrdererProvider provides capabilities information for orderer level config.

func NewOrdererProvider

func NewOrdererProvider(capabilities map[string]*cb.Capability) *OrdererProvider

ExpirationCheck specifies whether the orderer checks for identity expiration checks when validating messages

func (*OrdererProvider) HasCapability

func (cp *OrdererProvider) HasCapability(capability string) bool

HasCapability returns true if the capability is supported by this binary.

func (*OrdererProvider) Kafka2RaftMigration

func (cp *OrdererProvider) Kafka2RaftMigration() bool

Kafka2RaftMigration checks whether the orderer permits a Kafka to Raft migration.

func (*OrdererProvider) PredictableChannelTemplate

func (cp *OrdererProvider) PredictableChannelTemplate() bool

PredictableChannelTemplate specifies whether the v1.0 undesirable behavior of setting the /Channel group's mod_policy to "" and copying versions from the channel config should be fixed or not.

func (*OrdererProvider) Resubmission

func (cp *OrdererProvider) Resubmission() bool

Resubmission specifies whether the v1.0 non-deterministic commitment of tx should be fixed by re-submitting the re-validated tx.

func (OrdererProvider) Supported

func (r OrdererProvider) Supported() error

Supported checks that all of the required capabilities are supported by this binary.

func (*OrdererProvider) Type

func (cp *OrdererProvider) Type() string
