Class Config


  • public class Config
extends java.lang.Object
    Config allows for a global config of the toolkit. Central location for all toolkit configuration defaults. Has a local config file that can override any property defaults. Config file can be relocated via a system property "org.hyperledger.fabric.sdk.configuration". Any property can be overridden with environment variable and then overridden with a java system property. Property hierarchy goes System property overrides environment variable which overrides config file for default values specified here.
