  number

Properties

• description

  string
• id

Properties

• attributes

  object optional

  A map of attribute name to expected value, for example { name: 'Root directory', checkbox_mixed: true }. String attribute values may be specified as a regex, for example { name: /stralia$/ }.

  • float
  • boolean

• role

  RoleType optional
• state

  object optional

  A map of StateType to boolean, indicating for each state whether it should be set or not. For example: { StateType.disabled: false } would only match if StateType.disabled was not present in the node's state object.
