Vaultaire

Query DSL and data access utilities for Corda developers.

See complete documentation at https://manosbatsis.github.io/vaultaire

Query DSL

Use DSL will make your queries much easier to read and maintain. Each query DSL is automatically (re)generated at build time using annotation processing.

Usage example:

val queryCriteria: QueryCriteria = booksQuery {
    and {
    	// Check publisher?
        if(checkPublisher) fields.publisher `==` "Corda Books Ltd."
        or {
            fields.title  `==` "A book on Corda"
            fields.author `!=` "John Doe"
        }
    }
    orderBy {
        fields.title sort DESC
    }
}.toCriteria()

For more details see Query DSL.

State Services

Vaultaire's StateService components provide a simple, consistent API to load, query and track vault states.

StateService implementations are usually auto-generated at build-time and specific to a ContractState type. They also help decouple your code from ServiceHub and CordaRPCOps amd help increase code reuse in and out of a Node, i.e. between cordapps and their clients.

For more details see State Services.

RSQL Plugin

A plugin with support for RSQL, a URL-friendly query language for dynamic, complex queries and maintenance-free REST endpoints for searching the Vault.

For more details see RSQL Support.

Accounts Plugin

A plugin for adding Corda Accounts support to Vaultaire's runtime and build-time modules.

For more details see Corda Accounts.

State DTOs

Maintaining Data Transfer Objects for your contract states can be a mundane, error-prone task. Vaultaire’s annotation processing automates this by (re)generating those DTOs for you.

Other Utils

Vaultaire includes a few other utilities like:

• REST-friendly pages for query results.
• Annotation to generate responder flows from commonly used supertypes.
