clara.rules.durability.fressian — com.cerner/clara-rules 0.21.2

A default Fressian-based implementation of d/ISessionSerializer.

Note! Currently this only supports the clara.rules.memory.PersistentLocalMemory implementation of memory.

create-session-serializer clj

(create-session-serializer in-or-out-stream)

(create-session-serializer in-stream out-stream)

Inputs: ([in-or-out-stream :- (s/pred (some-fn (fn* [p1__9879#] (instance? InputStream p1__9879#)) (fn* [p1__9880#] (instance? OutputStream p1__9880#))) "java.io.InputStream or java.io.OutputStream")] [in-stream :- (s/maybe InputStream) out-stream :- (s/maybe OutputStream)])

Creates an instance of FressianSessionSerializer which implements d/ISessionSerializer by using Fressian serialization for the session structures.

In the one arity case, takes either an input stream or an output stream. This arity is intended for creating a Fressian serializer instance that will only be used for serialization or deserialization, but not both. e.g. This is often convenient if serialization and deserialization are not done from the same process. If it is to be used for serialization, then the stream given should be an output stream. If it is to be used for deserialization, then the stream to be given should be an input stream.

In the two arity case, takes an input stream and an output stream. These will be used for deserialization and serialization within the created Fressian serializer instance, respectively.

Note! Currently this only supports the clara.rules.memory.PersistentLocalMemory implementation of memory.

FressianSessionSerializer clj

handlers clj

A structure tying together the custom Fressian write and read handlers used by FressianSessionSerializer's.

read-handler-lookup clj

read-handlers clj

All Fressian read handlers used by FressianSessionSerializer's.

read-record clj

(read-record rdr)

(read-record rdr add-fn)

Same as read-with-meta, but with Clojure record support. The type of the record will be preserved.

read-with-meta clj

(read-with-meta rdr build-fn)

Reads an object from the reader that was written via write-with-meta. If the object was written with metadata the metadata will be associated on the object returned.

record-map-constructor-name clj

(record-map-constructor-name rec)

Return the 'map->' prefix, factory constructor function for a Clojure record.

write-handler-lookup clj

write-handlers clj

All Fressian write handlers used by FressianSessionSerializer's.

write-map clj

(write-map w m)

Writes a map as Fressian with the tag 'map' and all keys cached.

write-record clj

(write-record w tag rec)

Same as write-with-meta, but with Clojure record support. The type of the record will be preserved.

write-with-meta clj

(write-with-meta w tag o)

(write-with-meta w tag o write-fn)

Writes the object to the writer under the given tag. If the record has metadata, the metadata will also be written. read-with-meta will associated this metadata back with the object when reading.
