Role

Parse. Role

Represents a Role on the Parse server. Roles represent groupings of Users for the purposes of granting permissions (e.g. specifying an ACL for an Object). Roles are specified by their sets of child users and child roles, all of which are granted any permissions that the parent role has.

Roles must have a name (which cannot be changed after creation of the role), and must specify an ACL.

Constructor

new Role(name, acl)

Parameters:
Name Type Description
name String

The name of the Role to create.
acl Parse.ACL

The ACL for this role. Roles must have an ACL. A Parse.Role is a local representation of a role persisted to the Parse cloud.
