PaperTiger.Store.BalanceTransactions (PaperTiger v0.9.20)

View Source

ETS-backed storage for BalanceTransaction resources.

Uses the shared store pattern via use PaperTiger.Store which provides:

  • GenServer wraps ETS table
  • Reads go directly to ETS (concurrent, fast)
  • Writes go through GenServer (serialized, safe)

Architecture

  • ETS Table: :paper_tiger_balance_transactions (public, read_concurrency: true)
  • GenServer: Serializes writes, handles initialization
  • Shared Implementation: All CRUD operations via PaperTiger.Store

Examples

# Direct read (no GenServer bottleneck)
{:ok, txn} = PaperTiger.Store.BalanceTransactions.get("txn_123")

# Serialized write
txn = %{id: "txn_123", source: "ch_123", ...}
{:ok, txn} = PaperTiger.Store.BalanceTransactions.insert(txn)

# Query helpers (direct ETS access)
txns = PaperTiger.Store.BalanceTransactions.find_by_source("ch_123")

Summary

Functions

Returns a specification to start this module under a supervisor.

Clears all balance_transactions from the store (all namespaces).

Clears all balance_transactions for a specific namespace.

Counts total balance_transactions in current namespace.

Deletes a balance_transaction from the store.

Finds balance transactions by source ID.

Retrieves a balance_transaction by ID.

Inserts a balance_transaction into the store.

Lists all balance_transactions with optional pagination.

Returns all items in a specific namespace.

Returns the ID prefix for this resource.

Starts the balance_transaction store GenServer.

Functions

child_spec(init_arg)

Returns a specification to start this module under a supervisor.

See Supervisor.

clear()

@spec clear() :: :ok

Clears all balance_transactions from the store (all namespaces).

Serialized write - goes through GenServer.

Useful for test cleanup. Note: This clears ALL data, not just the current namespace. For namespace-specific cleanup, use clear_namespace/1.

clear_namespace(namespace)

@spec clear_namespace(pid() | :global) :: :ok

Clears all balance_transactions for a specific namespace.

Used by PaperTiger.Test to clean up after each test.

count()

@spec count() :: non_neg_integer()

Counts total balance_transactions in current namespace.

Direct ETS access - does not go through GenServer.

delete(id)

@spec delete(String.t()) :: :ok

Deletes a balance_transaction from the store.

Serialized write - goes through GenServer. Data is scoped to the current test namespace.

find_by_source(source_id)

@spec find_by_source(String.t()) :: [map()]

Finds balance transactions by source ID.

Direct ETS access - does not go through GenServer.

get(id)

@spec get(String.t()) :: {:ok, map()} | {:error, :not_found}

Retrieves a balance_transaction by ID.

Direct ETS access - does not go through GenServer. Data is scoped to the current test namespace.

insert(item)

@spec insert(map()) :: {:ok, map()}

Inserts a balance_transaction into the store.

Serialized write - goes through GenServer to prevent race conditions. Data is scoped to the current test namespace.

list(opts \\ %{})

@spec list(keyword() | map()) :: PaperTiger.List.t()

Lists all balance_transactions with optional pagination.

Direct ETS access - does not go through GenServer. Data is scoped to the current test namespace.

Options

  • :limit - Number of items (default: 10, max: 100)
  • :starting_after - Cursor for pagination
  • :ending_before - Reverse cursor

list_namespace(namespace)

@spec list_namespace(pid() | :global) :: [map()]

Returns all items in a specific namespace.

Useful for debugging test isolation.

prefix()

@spec prefix() :: String.t() | nil

Returns the ID prefix for this resource.

start_link(opts \\ [])

@spec start_link(keyword()) :: GenServer.on_start()

Starts the balance_transaction store GenServer.

table_name()

@spec table_name() :: atom()

Returns the ETS table name for this store.

update(item)

@spec update(map()) :: {:ok, map()}

Updates a balance_transaction in the store.

Serialized write - goes through GenServer. Data is scoped to the current test namespace.
