Method Details

incOps

public static void incOps()

During a doubling test, the provided code may call incOps and/or addOps. If either is called, then the number of operations so recorded will be reported by run.

addOps

public static void addOps(int count)

During a doubling test, the provided code may call incOps and/or addOps. If either is called, then the number of operations so recorded will be reported by run.

run

public static void run(int initialValue,
 int numValues,
 Consumer<Integer> timed)

See fully parameterized run for a description. In this abbreviated form, numTestsPerValue is 1. setup does nothing, therefore no value is provided to timed.

run

public static void run(int initialValue,
 int numValues,
 Consumer<Integer> setup,
 Consumer<Integer> timed)

See fully parameterized run for a description. In this abbreviated form, numTestsPerValue is 1. No value is passed from setup to timed.

run

public static void run(int initialValue,
 int numValues,
 int numTestsPerValue,
 Consumer<Integer> setup,
 Consumer<Integer> timed)

See fully parameterized run for a description. In this abbreviated form, no value is passed from setup to timed.

run

public static <T> void run(int initialValue,
 int numValues,
 Function<Integer,T> setup,
 BiConsumer<Integer,T> timed)

See fully parameterized run for a description. In this abbreviated form, numTestsPerValue is 1.

run

public static <T> void run(int initialValue,
 int numValues,
 int numTestsPerValue,
 Function<Integer,T> setup,
 Consumer<T> timed)

See fully parameterized run for a description. In this abbreviated form, the integer value is not passed to timed.

run

public static <T> void run(int initialValue,
 int numValues,
 Function<Integer,T> setup,
 Consumer<T> timed)

See fully parameterized run for a description. In this abbreviated form, numTestsPerValue is 1. The integer value is not passed to timed.

run

public static <T> void run(int initialValue,
 int numValues,
 int numTestsPerValue,
 Function<Integer,T> setup,
 BiConsumer<Integer,T> timed)

Run the function timed with increasing large values for the first integer parameter (N). Running time is reported to the console. Initial value of N is given by initialValue. N doubles each time the test is run. The number of different values for N is given by numValues. If numTestsPerValue is larger than one, then the test will be run multiple times for each N, and the average time reported. The setup function is called before timed, and the result (of type T) is provided to timed as the second parameter. setup is called once before each call to timed.

runOnce

private static <T> void runOnce(int value,
 int numTestsPerValue,
 Function<Integer,T> setup,
 BiConsumer<Integer,T> timed)

runLong

public static void runLong(long initialValue,
 int numValues,
 Consumer<Long> timed)

See fully parameterized runLong for a description. In this abbreviated form, numTestsPerValue is 1. setup does nothing, therefore no value is provided to timed.

runLong

public static void runLong(long initialValue,
 int numValues,
 Consumer<Long> setup,
 Consumer<Long> timed)

See fully parameterized runLong for a description. In this abbreviated form, numTestsPerValue is 1. No value is passed from setup to timed.

runLong

public static void runLong(long initialValue,
 int numValues,
 int numTestsPerValue,
 Consumer<Long> setup,
 Consumer<Long> timed)

See fully parameterized runLong for a description. In this abbreviated form, no value is passed from setup to timed.

runLong

public static <T> void runLong(long initialValue,
 int numValues,
 Function<Long,T> setup,
 BiConsumer<Long,T> timed)

See fully parameterized runLong for a description. In this abbreviated form, numTestsPerValue is 1.

runLong

public static <T> void runLong(long initialValue,
 int numValues,
 int numTestsPerValue,
 Function<Long,T> setup,
 Consumer<T> timed)

See fully parameterized runLong for a description. In this abbreviated form, the integer value is not passed to timed.

runLong

public static <T> void runLong(long initialValue,
 int numValues,
 Function<Long,T> setup,
 Consumer<T> timed)

See fully parameterized runLong for a description. In this abbreviated form, numTestsPerValue is 1. The integer value is not passed to timed.

runLong

public static <T> void runLong(long initialValue,
 int numValues,
 int numTestsPerValue,
 Function<Long,T> setup,
 BiConsumer<Long,T> timed)

Run the function timed with increasing large values for the first integer parameter (N). Running time is reported to the console. Initial value of N is given by initialValue. N doubles each time the test is runLong. The number of different values for N is given by numValues. If numTestsPerValue is larger than one, then the test will be runLong multiple times for each N, and the average time reported. The setup function is called before timed, and the result (of type T) is provided to timed as the second parameter. setup is called once before each call to timed.

runOnce

private static <T> void runOnce(long value,
 int numTestsPerValue,
 Function<Long,T> setup,
 BiConsumer<Long,T> timed)
