Class PermissionPredicates

java.lang.Object
net.fabricmc.fabric.api.permission.v1.PermissionPredicates
public final class PermissionPredicates extends Object
Utility methods for creating permission predicates, mainly to be used for commands, but will work in any context that needs a predicate.

Example usage: 

CommandRegistrationCallback.EVENT.register((dispatcher, _, _) -> {
    dispatcher.register(literal("modcommand")
    	   // By using direct Identitier
        .requires(PermissionPredicates.require(Identifier.fromNamespaceAndPath("mymod", "command/main"), true))
        .executes(ModCommands::executeMainCommand)
        .then(literal("admin")
            // By using boolean permission node
            .requires(PermissionPredicates.require(PermissionNode.of(Identifier.fromNamespaceAndPath("mymod", "command/admin")), PermissionLevel.ADMINS))
            .executes(ModCommands::executeMainCommand)
        )
});
