InMemoryDatabaseConnection

public final class InMemoryDatabaseConnection : DatabaseConnection

This class provides a database connection to an in-memory database.

  • Declaration

    Swift

    public let eventLoop: EventLoop

  • The last committed transaction version.

    Declaration

    Swift

    public private(set) var currentVersion: Int64

  • This initializer creates a new database.

    Declaration

    Swift

    public init(eventLoop: EventLoop)

  • This method starts a transaction on the database.

    Declaration

    Swift

    public func startTransaction() -> Transaction

    Return Value

    The new transaction.

  • This method commits a transaction to the database.

    The transaction must be one that was created by calling startTransaction on this database. Otherwise, it will be rejected.

    If the transaction has added a read conflict on any keys that have changed since the transaction’s readVersion, this will reject the transaction.

    If the transaction is valid this will merge in the keys and values that were changed in the transaction.

    Declaration

    Swift

    public func commit(transaction: Transaction) -> EventLoopFuture<()>

    Parameters

    transaction

    The transaction to commit.

    Return Value

    A future that will fire when the transaction has finished committing. If the transaction is rejected, the future will throw an error.
