addTokenToAllT

addTokenToAllT is a function in a token management system used to augment the token set associated with a generic token type T. The function operates on a collection or registry named AllT, which stores tokens that share the same type T. Its primary purpose is to propagate a new token or token descriptor to every existing instance in AllT, enabling consistent tagging, metadata, or behavioral extensions across the entire token stream.

Typical usage involves calling addTokenToAllT with a token descriptor and the AllT collection, optionally providing options to control de-duplication or conflict handling. When invoked, the function validates the input token, iterates over each token in AllT that matches type T, and attaches the new token to its metadata or tag list. If the target token already includes the descriptor, the function may skip it or update existing metadata depending on the configured policy. The operation may emit change events to notify dependent components such as analyzers or renderers.

Return values commonly include the number of tokens updated or a status object indicating success and any encountered conflicts. The function is typically designed to be O(n) with respect to the size of AllT, and attention is given to thread safety in concurrent environments.

Common use cases include introducing a new diagnostic tag to all tokens of a type, applying a global feature flag, or broadening semantic annotations during a preprocessing stage. See also: Token, TokenType T, AllT, token metadata, and tokenizer pipeline.
