Types

StepHandle

class StepHandle<T>

Type-safe, unique identifier for a step in a transaction.

TransactionPlan

class TransactionPlan

Mutable container for building a sequence of database operations to be executed atomically.

TransactionPlanResult

class TransactionPlanResult(results: Map<StepHandle<*>, Any?>)

Stores the results of an executed transaction plan in a safe manner. Allows retrieving results using StepHandle instead of indices.

TransactionPropagation

enum TransactionPropagation : Enum<TransactionPropagation>

Defines transaction behavior when it is launched in the context of an already existing transaction. Reflects key propagation strategies from Spring Framework.

TransactionStep

class TransactionStep<T>(val builder: QueryBuilder<*>, val executionLogic: (builder: QueryBuilder<*>, params: Map<String, Any?>) -> DataResult<T>, val params: Map<String, Any?>)

Encapsulates a single, deferred database operation within a TransactionPlan.

TransactionValue

sealed class TransactionValue<T>

Represents a value in a transaction step. Enables passing both constant values and dynamic references to results of previous steps in the same transaction.

Functions

map

fun <IN, OUT> TransactionValue<IN>.map(transformation: (IN) -> OUT): TransactionValue<OUT>

Applies a transformation to a TransactionValue, creating a new, transformed value. This function is type-safe.

toTransactionValue

fun <T> T.toTransactionValue(): TransactionValue.Value<T>

Converts any value to a type-safe instance of TransactionValue.Value.
