Package org.hyperledger.fabric.gateway

package org.hyperledger.fabric.gateway
As of Fabric v2.5, replaced by the Fabric Gateway client API.

This package provides the set of interfaces that enable a Java application to interact with a Fabric blockchain network. It provides a simple API to submit transactions to a ledger or query the contents of a ledger with minimal code. The Gateway SDK implements the Fabric programming model as described in the Developing Applications chapter of the Fabric documentation.
