Class GraphConfig

java.lang.Object

uk.gov.gchq.gaffer.graph.GraphConfig

public final class GraphConfig
extends Object

GraphConfig contains configuration for Graphs. This configuration is used along side a Schema and StoreProperties to create a Graph. This configuration is made up of graph properties such as a graphId, GraphLibrary, a graph View and GraphHooks. To create an instance of GraphConfig you can either use the GraphConfig.Builder or a json file. If you wish to write a GraphHook in a separate json file and include it, you can do it by using the GraphHookPath GraphHook and setting the path field within.
