Example 6 with MycatPropertyConf

use of io.mycat.memory.unsafe.utils.MycatPropertyConf in project Mycat-Server by MyCATApache.

the class TaskMemoryManagerSuite method encodePageNumberAndOffsetOffHeap.

@Test
public void encodePageNumberAndOffsetOffHeap() {
    final MycatPropertyConf conf = new MycatPropertyConf().set("mycat.memory.offHeap.enabled", "true").set("mycat.memory.offHeap.size", "1000");

    final MemoryBlock dataPage = manager.allocatePage(256, null);
    // In off-heap mode, an offset is an absolute address that may require more than 51 bits to
    // encode. This map exercises that corner-case:
    final long offset = ((1L << DataNodeMemoryManager.OFFSET_BITS) + 10);
    final long encodedAddress = manager.encodePageNumberAndOffset(dataPage, offset);
    Assert.assertEquals(null, manager.getPage(encodedAddress));
    Assert.assertEquals(offset, manager.getOffsetInPage(encodedAddress));
