Field

data class Field<T>(val handle: StepHandle<*>, val columnName: String?, val rowIndex: Int = 0) : TransactionValue.FromStep<T>

Fetches a single value from a specific cell (row, column). Ideal for retrieving the ID from a just-inserted row.

handle

Handle to the step from which the data originates.

columnName

Name of the column from which the value should be fetched.

rowIndex

Row index (default 0, i.e., first).

The expected type of the field's value.

Constructors

constructor(handle: StepHandle<*>, columnName: String?, rowIndex: Int = 0)

constructor(handle: StepHandle<*>, rowIndex: Int = 0)

open override val handle: StepHandle<*>

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