Examples with Buffer org.apache.karaf.audit.util.Buffer used on opensource projects

Example 1 with Buffer

use of org.apache.karaf.audit.util.Buffer in project karaf by apache.

the class TestPerf method testGelfTimestamp.

@Test
public void testGelfTimestamp() throws Exception {
    long timestamp = System.currentTimeMillis();
    int iterations = 1000000;
    for (int p = 0; p < 10; p++) {
        Buffer buffer = new Buffer(Buffer.Format.Json);
        long t0 = measure(() -> {
            buffer.clear();
            long secs = timestamp / 1000;
            int ms = (int) (timestamp - secs * 1000);
            buffer.format(secs);
            buffer.append('.');
            int temp = ms / 100;
            buffer.append((char) (temp + '0'));
            ms -= 100 * temp;
            temp = ms / 10;
            buffer.append((char) (temp + '0'));
            ms -= 10 * temp;
            buffer.append((char) (ms + '0'));
            return null;
        }, iterations);
        System.out.println("t0 = " + t0);
        long t1 = measure(() -> {
            buffer.clear();
            long secs = timestamp / 1000;
            int ms = (int) (timestamp - secs * 1000);
            buffer.format(Long.toString(secs));
            buffer.append('.');
            int temp = ms / 100;
            buffer.append((char) (temp + '0'));
            ms -= 100 * temp;
            temp = ms / 10;
            buffer.append((char) (temp + '0'));
            ms -= 10 * temp;
            buffer.append((char) (ms + '0'));
            return null;
        }, iterations);
        System.out.println("t1 = " + t1);
        long t2 = measure(() -> {
            buffer.clear();
            new Formatter(buffer).format("%.3f", ((double) timestamp) / 1000.0);
            return null;
        }, iterations);
        System.out.println("t2 = " + t2);
    }
}

Example 2 with Buffer

use of org.apache.karaf.audit.util.Buffer in project karaf by apache.

the class TestPerf method testFormatString.

@Test
public void testFormatString() throws Exception {
    int iterations = 10000000;
    for (int i = 0; i < 10; i++) {
        final Buffer buffer0 = new Buffer(Buffer.Format.Json);
        long t0 = measure(() -> {
            buffer0.clear();
            buffer0.format("This is \"\n\tquite\n\tq\n\ta\n\tlong\n\tquote.\"\nIndeed !\n");
            return null;
        }, iterations);
        System.out.println("json = " + t0);
        final Buffer buffer1 = new Buffer(Buffer.Format.Syslog);
        long t1 = measure(() -> {
            buffer1.clear();
            buffer1.format("This is \"\n\tquite\n\tq\n\ta\n\tlong\n\tquote.\"\nIndeed !\n");
            return null;
        }, iterations);
        System.out.println("syslog = " + t1);
    }
