Interface ResourceConsumptionEstimator

All Known Implementing Classes:

ExampleSetResourceConsumptionEstimator, PolynomialExampleSetResourceConsumptionEstimator

public interface ResourceConsumptionEstimator

Estimates the resource consumption (CPU time and memory usage) of an Operator based on its current input. The methods in this interface do not take any arguments. Instead, they are backed by an operator and consider its current input.

Method Summary

long	estimateMemoryConsumption() Returns the estimated number of bytes required when executing this operator.
long	estimateRuntime() Returns the estimated number of CPU-cycles.
PolynomialFunction	getCpuFunction() Returns the cpu function.
PolynomialFunction	getMemoryFunction() Returns the memory function.

Method Detail

estimateRuntime

long estimateRuntime()

Returns the estimated number of CPU-cycles. If, for any reason, computation is impossible, -1 should be returned.

estimateMemoryConsumption

long estimateMemoryConsumption()

Returns the estimated number of bytes required when executing this operator. If, for any reason, computation is impossible, -1 should be returned.

getCpuFunction

PolynomialFunction getCpuFunction()

Returns the cpu function.

getMemoryFunction

PolynomialFunction getMemoryFunction()

Returns the memory function.
