the class DoubleAdderTest method test_long_add.

public void test_long_add() throws Exception {
    DoubleAdder adder = new DoubleAdder();
    adder.add(3);
    String json = JSON.toJSONString(adder);
    assertEquals("{\"value\":3.0}", json);

Example 2 with DoubleAdder

use of java.util.concurrent.atomic.DoubleAdder in project spring-boot by spring-projects.

the class BufferGaugeServiceSpeedTests method raw.

@Theory
public void raw(String input) throws Exception {
    iterate("writeRaw");
    double rate = number / watch.getLastTaskTimeMillis() * 1000;
    System.err.println("Rate(" + count + ")=" + rate + ", " + watch);
    watch.start("readRaw" + count);
    for (String name : names) {
        this.gauges.forEach(Pattern.compile(name).asPredicate(), new BiConsumer<String, GaugeBuffer>() {

            @Override
            public void accept(String name, GaugeBuffer value) {
                err.println(name + "=" + value);
            }
        });
    }
    final DoubleAdder total = new DoubleAdder();
    this.gauges.forEach(Pattern.compile(".*").asPredicate(), new BiConsumer<String, GaugeBuffer>() {

        @Override
        public void accept(String name, GaugeBuffer value) {
            total.add(value.getValue());
        }
    });
    watch.stop();
    System.err.println("Read(" + count + ")=" + watch.getLastTaskTimeMillis() + "ms");
    assertThat(number * threadCount < total.longValue()).isTrue();
}
