Module CCHashTrie.TransientSource

Transient Identifiers

Sourcetype t

Identifiers for transient modifications. A transient modification is uniquely identified by a Transient.t. Once Transient.freeze r is called, r cannot be used to modify the structure again.

Sourceval create : unit -> t

Create a new, active ID.

Sourceval equal : t -> t -> bool

Equality between IDs.

Sourceval frozen : t -> bool

frozen i returns true if freeze i was called before. In this case, the ID cannot be used for modifications again.

Sourceval active : t -> bool

active i is not (frozen i).

Sourceval freeze : t -> unit

freeze i makes i unusable for new modifications. The values created with i will now be immutable.

Sourceval with_ : (t -> 'a) -> 'a

with_ f creates a transient ID i, calls f i, freezes the ID i and returns the result of f i.

Sourceexception Frozen

Raised when a frozen ID is used.
