Example 76 with Buffer

use of io.vertx.core.buffer.Buffer in project vert.x by eclipse.

the class BufferTest method testGetSetUnsignedShort.

private void testGetSetUnsignedShort(boolean isLE) throws Exception {
    int numShorts = 100;
    Buffer b = Buffer.buffer(numShorts * 2);
    for (short i = 0; i < numShorts; i++) {
        if (isLE) {
            b.setUnsignedShortLE(i * 2, (short) (Short.MAX_VALUE + (int) i));
        } else {
            b.setUnsignedShort(i * 2, (short) (Short.MAX_VALUE + (int) i));
        }
    }
    for (short i = 0; i < numShorts; i++) {
        if (isLE) {
            assertEquals(Integer.toUnsignedLong(Short.MAX_VALUE + i), b.getUnsignedShortLE(i * 2));
        } else {
            assertEquals(Integer.toUnsignedLong(Short.MAX_VALUE + i), b.getUnsignedShort(i * 2));
        }
    }
}
