Class OpenapiContractRegistry

java.lang.Object
ch.nexsol.gateway.validation.OpenapiContractRegistry
public class OpenapiContractRegistry extends Object
Reads the OpenAPI contracts the filter validates against, and keeps each one for as long as the gateway runs.

Reading and parsing a document blocks, so it happens on the bounded elastic scheduler and only once per location: the first request through a route pays for it, every later one gets the parsed contract straight away. A load that failed is not remembered, so a contract that became reachable again is picked up by the next request rather than needing a restart.
