DataFrameSolverStateTracker

class DataFrameSolverStateTracker(solver: Solver, columns: List<DataFrameColumn> = defaultColumns) : AbstractSolverStateTracker(source)

An autonomous tracker that collects iterations in memory and compiles them into a strongly-typed DataFrame. If the solver is executed multiple times, this tracker accumulates the data and rebuilds the DataFrame to include all consecutive runs.

Functions

clearData

fun clearData()

Clears all accumulated data in memory if needed.

consume

protected open override fun consume(snapshot: SolverStateSnapshot)

Defines how the concrete tracker handles the mathematical state payload.

onLifecycleEvent

protected open override fun onLifecycleEvent(status: SolverStatus)

Optional hook for subclasses to react to lifecycle changes (e.g., opening/closing files on INITIALIZED/COMPLETED).
