Trait Sabre\DAVACL\ACLTrait

This trait is a default implementation of the IACL interface.

In many cases you only want to implement 1 or to of the IACL functions, this trait allows you to be a bit lazier.

By default this trait grants all privileges to the owner of the resource.

Methods
`public`	`getOwner(): string\|null` Returns the owner principal. Returns the owner principal. This must be a url to a principal, or null if there's no owner	#
`public`	`getGroup(): string\|null` Returns a group principal. Returns a group principal. This must be a url to a principal, or null if there's no owner	#
`public`	`getACL(): array` Returns a list of ACE's for this node. Returns a list of ACE's for this node. Each ACE has the following properties: 'privilege', a string such as {DAV:}read or {DAV:}write. These are currently the only supported privileges 'principal', a url to the principal who owns the node 'protected' (optional), indicating that this ACE is not allowed to be updated.	#
`public`	`setACL(array $acl)` Updates the ACL. Updates the ACL. This method will receive a list of new ACE's as an array argument.	#
`public`	`getSupportedPrivilegeSet(): array\|null` Returns the list of supported privileges for this node. Returns the list of supported privileges for this node. The returned data structure is a list of nested privileges. See Sabre\DAVACL\Plugin::getDefaultSupportedPrivilegeSet for a simple standard structure. If null is returned from this method, the default privilege set is used, which is fine for most common usecases.	#
