Constructor Details

MultiEvaluator

public MultiEvaluator(Collection<InputType> input,
 Function<InputType, OutputType> function,
 ExternalAlgorithmHaltingConditions externalHaltingConditions,
 BiFunction<InputType, String, OutputType> outputIfTimeout)

Creates an evaluator using the same function for batch and lazy execution.

Parameters:

input - the inputs to evaluate

function - the evaluation function used in both modes

externalHaltingConditions - the external stop conditions to observe

outputIfTimeout - the fallback result producer when a timeout occurs

MultiEvaluator

public MultiEvaluator(Collection<InputType> input,
 Function<InputType, OutputType> batchFunction,
 Function<InputType, OutputType> lazyFunction,
 ExternalAlgorithmHaltingConditions externalHaltingConditions,
 BiFunction<InputType, String, OutputType> outputIfTimeout)

Creates an evaluator with distinct batch and lazy functions.

Parameters:

input - the inputs to evaluate

batchFunction - the function used for batch processing

lazyFunction - the function used for lazy processing

externalHaltingConditions - the external stop conditions to observe

outputIfTimeout - the fallback result producer when a timeout occurs

Method Details

batchEvaluate

public final Iterable<OutputType> batchEvaluate()

Evaluates all queries in a batch and returns a list of QueryEvaluationOutput.

Returns:

A list of QueryEvaluationOutput, each containing a query and its corresponding iterator of substitutions.

lazyEvaluate

public final Iterable<OutputType> lazyEvaluate()

Provides lazy evaluation for the queries, yielding QueryEvaluationOutput for each query.

Returns:

An iterable for lazy evaluation of query results, each as a QueryEvaluationOutput.
