TriePrefix (gb.data)

This class provides a read-only view of part of a Trie. It lets you examine keys with a common prefix.

This class is not creatable.

This class acts like a read-only array.

This class is enumerable with the FOR EACH keyword.

Properties

Key	Return the relative key of the last enumerated object.
Prefix	Return the prefix string of this object.

Methods

Add	Add bytes to the prefix. If the extended prefix does not exist within the Trie, an error is raised.
Exist	Return if the given key exists relative to the prefix. This returns the same as `hTrie.Exist(hTriePrefix.Prefix & RelKey)`.
Remove	Remove bytes from the end of the prefix.

Searches begin in the middle of the Trie and are thus faster (compared to repeated lookups under the same prefix).

TriePrefix objects are invalidated when you change the Trie, so be careful if you store them persistently.
