Chronicle.EventSequences.EventSequence (cratis_chronicle v0.2.0)

Represents a Chronicle event sequence.

Use this module when you want to work with a non-default event sequence and keep the event sequence identifier close to the append/query operations.

Summary

Types

t()

Functions

append(event_sequence, event_source_id, event, opts \\ [])

Appends a single event to the event sequence.

append_many(event_sequence, event_source_id, events, opts \\ [])

Appends multiple events to the event sequence.

get_for_event_source(event_sequence, event_source_id, opts \\ [])

Gets events for the given event source from the event sequence.

get_tail_sequence_number(event_sequence, event_source_id \\ nil, opts \\ [])

Gets the tail sequence number for the event sequence.

has_events_for?(event_sequence, event_source_id, opts \\ [])

Checks whether the event sequence has events for the given event source id.

new(id, opts \\ [])

Creates an event sequence wrapper for the given event sequence id.

transactional(event_sequence)

Gets a transactional view of the event sequence that buffers appends in the current unit of work.

Types

t()

@type t() :: %Chronicle.EventSequences.EventSequence{id: String.t(), opts: keyword()}

Functions

append(event_sequence, event_source_id, event, opts \\ [])

@spec append(t(), String.t(), struct(), keyword()) :: :ok | {:error, term()}

Appends a single event to the event sequence.

append_many(event_sequence, event_source_id, events, opts \\ [])

@spec append_many(t(), String.t(), [struct()], keyword()) :: :ok | {:error, term()}

Appends multiple events to the event sequence.

get_for_event_source(event_sequence, event_source_id, opts \\ [])

@spec get_for_event_source(t(), String.t(), keyword()) ::
  {:ok, list()} | {:error, term()}

Gets events for the given event source from the event sequence.

get_tail_sequence_number(event_sequence, event_source_id \\ nil, opts \\ [])

@spec get_tail_sequence_number(t(), String.t() | nil, keyword()) ::
  {:ok, non_neg_integer()} | {:error, term()}

Gets the tail sequence number for the event sequence.

has_events_for?(event_sequence, event_source_id, opts \\ [])

@spec has_events_for?(t(), String.t(), keyword()) ::
  {:ok, boolean()} | {:error, term()}

Checks whether the event sequence has events for the given event source id.

new(id, opts \\ [])

@spec new(
  String.t(),
  keyword()
) :: t()

Creates an event sequence wrapper for the given event sequence id.

transactional(event_sequence)

@spec transactional(t()) :: Chronicle.EventSequences.TransactionalEventSequence.t()

Gets a transactional view of the event sequence that buffers appends in the current unit of work.
