   adapter, 
   resolvedMode, 
   options): TransactionContext

Parameters

Returns

TransactionContext

Accessors

Get Signature

get mode(): ResolvedTransactionMode

Get the transaction mode.

Returns

ResolvedTransactionMode

Get the current transaction mode.

Implementation of

ITransactionContext.mode

mutationCount

Get Signature

get mutationCount(): number

Get the current mutation count.

Returns

number

Get mutation count so far.

Implementation of

ITransactionContext.mutationCount

Methods

commit(): Promise<void>

Commit the transaction. The actual commit logic is determined by the mode.

Returns

Promise<void>

delete()

delete(key): void

Stage a delete operation.

Parameters

Returns

void

Implementation of

ITransactionContext.delete

getOptions()

getOptions(): Required<TransactionOptions>

Get transaction options.

Returns

Required<TransactionOptions>

getReadVersions()

getReadVersions(): Map<string, number>

Get the read versions map (for commit).

Returns

Map<string, number>

getStagedDeletes()

getStagedDeletes(): Set<string>

Get staged deletes.

Returns

Set<string>

getStagedWrites()

getStagedWrites(): Map<string, unknown>

Get staged writes.

Returns

Map<string, unknown>

hasPendingOperations()

hasPendingOperations(): boolean

Check if there are any pending operations.

Returns

boolean

read()

read<V>(key): Promise<V>

Read a value within the transaction. Tracks the version for conflict detection in optimistic mode.

Type Parameters

Parameters

Returns

Promise<V>

Implementation of

ITransactionContext.read

rollback()

rollback(): void

Rollback the transaction (discard staged operations).

Returns

void

set()

set(key, value): void

Stage a set operation.

Parameters

Returns

void

Implementation of

ITransactionContext.set

trackReadVersion()

trackReadVersion(key, version): void

Track a read version externally (for model operations).

Parameters

Returns

void
