Class OperationContext

java.lang.Object

org.episteme.core.technical.algorithm.OperationContext

public final class OperationContext
extends Object

Describes the context of a numerical operation for provider selection.

Instead of purely priority-based selection, OperationContext allows AlgorithmProvider.score(OperationContext) to make informed decisions based on data characteristics.

OperationContext ctx = new OperationContext.Builder()
    .dataSize(1_000_000)
    .addHint(OperationContext.Hint.DENSE)
    .build();

LinearAlgebraProvider best = ProviderSelector.select(
    LinearAlgebraProvider.class, ctx);
