Class CharacterPetAttributeService

Namespace

FishMMO.Database.Npgsql.Services

Assembly

FishMMO-DB.dll

Service for managing character pet attributes in the database. Provides async operations for CRUD operations on character pet attribute data. Uses the BaseService execution strategy for automatic retry on transient database failures. Returns DatabaseResult for consistent, safe error handling.

Constructors

CharacterPetAttributeService(INpgsqlDbContextFactory)

Initializes a new instance of the CharacterPetAttributeService class.

public CharacterPetAttributeService(INpgsqlDbContextFactory dbContextFactory)

Parameters

dbContextFactory INpgsqlDbContextFactory

Factory for creating database contexts.

Exceptions

ArgumentNullException

Thrown when dbContextFactory is null.

Methods

CountAsync(long, CancellationToken)

Counts items for the given key.

public Task<DatabaseResult<int>> CountAsync(long characterId, CancellationToken cancellationToken = default)

Parameters

characterId long

cancellationToken CancellationToken

Token to cancel the operation.

Returns

Task<DatabaseResult<int>>

DeleteAsync(long, long, CancellationToken)

Deletes the entity identified by the given key if incomingVersion is newer.

public Task<DatabaseResult> DeleteAsync(long characterId, long incomingVersion, CancellationToken cancellationToken = default)

Parameters

characterId long

incomingVersion long

The authoritative, monotonic version for this delete operation.

cancellationToken CancellationToken

Token to cancel the operation.

Returns

Task<DatabaseResult>

FetchAsync(long, CancellationToken)

Fetches a collection of items for the given key.

public Task<DatabaseResult<IReadOnlyList<CharacterPetAttributeData>>> FetchAsync(long characterId, CancellationToken cancellationToken = default)

Parameters

characterId long

cancellationToken CancellationToken

Token to cancel the operation.

Returns

Task<DatabaseResult<IReadOnlyList<CharacterPetAttributeData>>>

PersistAsync(CharacterPetAttributeData, CancellationToken)

Persists the provided data.

public Task<DatabaseResult<long>> PersistAsync(CharacterPetAttributeData attributeData, CancellationToken cancellationToken = default)

Parameters

attributeData CharacterPetAttributeData

cancellationToken CancellationToken

Token to cancel the operation.

Returns

Task<DatabaseResult<long>>

PersistAsync(IEnumerable<CharacterPetAttributeData>, CancellationToken)

Persists the provided items.

public Task<DatabaseResult<BulkWriteResult>> PersistAsync(IEnumerable<CharacterPetAttributeData> attributes, CancellationToken cancellationToken = default)

Parameters

attributes IEnumerable<CharacterPetAttributeData>

cancellationToken CancellationToken

Token to cancel the operation.

Returns

Task<DatabaseResult<BulkWriteResult>>

What the write actually did, or a failure.

Remarks

A successful result does not mean every supplied row was written. Batched writes are version-gated and the service filters what it cannot act on, so the outcome carries counts rather than a bare boolean — see BulkWriteResult, which explains which discrepancies a caller should care about and which are routine.
