This project is an idiomatic Scala wrapper around Web3J for Ethereum.
This project is an idiomatic Scala wrapper around Web3J for Ethereum.
This project is built with Scala 2.12, and requires the Java 8 runtime; it is not yet compatible with Java 9.This project promotes idiomatic Scala in the following ways:
- Variables and no-argument methods are actually names of properties, so
setandgetprefixes are not used. This means some properties do not have exactly the same name as their Web3J counterpart. - Zero-argument methods only require parentheses if they perform side effects.
- Scala data types are used to the maximum extent that makes sense. For example, scala.concurrent.Future.
- A functional programming style is encouraged by always returning immutable data types from methods. For example, scala.collection.immutable.List
The Ethereum JSON-RPC documentation was the source of many the comments incorporated into this Scaladoc.
The JSON-RPC default block parameter can represent a
QUANTITYor aTAG. Quantities are expressed as integer block numbers, and tags are strings with one of the values "latest", "earliest" or "pending". The Java implementation performs the same function as the underlying JSON-RPC implementation.Whisper is an experimental communication protocol of the Ethereum P2P protocol suite that allows for messaging between users' DApps (Ethereum Distributed Applications). Whisper uses the same network that the blockchain runs on. The protocol is separate from the blockchain, so smart contracts do not have access to whispered messages.
EthBlock and its internal types such as Block, TransactionObject and TransactionResult are returned by the following methods of com.micronautics.web3j.EthereumSynchronous and com.micronautics.web3j.EthereumASynchronous:
blockByHash,blockByNumber,uncleByBlockHashAndIndex,uncleByBlockNumberAndIndex. - Variables and no-argument methods are actually names of properties, so
