# A collection is an object that represents a list of nodes. A collection can be |
|||
# either live or static. Unless otherwise stated, a collection must be live. |
|||
# |
|||
# If a collection is live, then the attributes and methods on that object must |
|||
# operate on the actual underlying data, not a snapshot of the data. |
|||
# |
|||
# When a collection is created, a filter and a root are associated with it. |
|||
# |
|||
# The collection then represents a view of the subtree rooted at the |
|||
# collection’s root, containing only nodes that match the given filter. The view |
|||
# is linear. In the absence of specific requirements to the contrary, the nodes |
|||
# within the collection must be sorted in tree order. |
