ListRole¶

The idea of the ListRole is about to combine other roles (sub-roles) in the "and", "or" and "any N of" principle.

It stores the mode, the set of roles and the size of the quorum.

Basically, it has 3 types of modes:

All
Any
Quorum

Mode: All¶

Role could be performed only if set of keys could play all sub-roles

Mode: Any¶

Role could be performed if set of keys could play any role of the list

Mode: Quorum¶

Role could be played if set of keys could play any quorrum set of roles, e.g. at least any N subroles, controlled by the #setQuorum method

h1.How To.

There are 3 options for creating a ListRole by API:

constructor just with the role name;
constructor with the role name, the set of roles, and mode (ALL or ANY modes available only!)
constructor just for Quorum mode: role name, the set of roles and quorum size.

DSL:

role: [name](String) quorum_size: [number](Integer) mode: [All, Any, Quorum) roles:
[role1] ...
