Method Detail

provideContract

@Nonnull
public static org.hyperledger.fabric.gateway.Contract provideContract(@Nonnull
                                                                               ApplicationService applicationService)

Provides a Contract component that can be used to interact with the chaincode instantiated on a Hyperledger Fabric channel.

Parameters:

applicationService - An Application Service that contains all necessary credentials

Returns:

The contract object which represents a chaincode on a Hyperledger Fabric channel

provideNetwork

@Nonnull
public static org.hyperledger.fabric.gateway.Network provideNetwork(@Nonnull
                                                                             ChannelService channelService)

Provides a Network component that can be used to get chaincodes instantiated on the channel or interact with the ledger itself.

Parameters:

channelService - A Channel Service that contains all necessary credentials

Returns:

The network object which represents a channel on a Hyperledger Fabric network

provideContract

@Nonnull
public static org.hyperledger.fabric.gateway.Contract provideContract()

Provides a Contract component that can be used to interact with the chaincode instantiated on a Hyperledger Fabric channel. This method expects only one user-provided service to be in the environment of the Cloud Foundry application.

Returns:

The contract object which represents a chaincode on a Hyperledger Fabric channel

Throws:

IllegalStateException - if there are no or more than one user-provided services

IllegalArgumentException - if the user-provided service is not a hyperledger-fabric ApplicationService or some credentials are missing or can not be parsed

provideNetwork

@Nonnull
public static org.hyperledger.fabric.gateway.Network provideNetwork()

Provides a Network component that can be used to get chaincodes installed on the channel or interact with the ledger itself. This method expects only one user-provided service to be in the environment of the Cloud Foundry application.

Returns:

The network object which represents a channel on a Hyperledger Fabric network

Throws:

IllegalStateException - if there are no or more than one user-provided services

IllegalArgumentException - if the user-provided service is not a hyperledger-fabric ChannelService or some credentials are missing or can not be parsed
