### 4.3 Lease Manager
```java
package jcifs.internal.smb2.lease;

import java.util.concurrent.ConcurrentHashMap;
import java.util.concurrent.locks.ReadWriteLock;
import java.util.concurrent.locks.ReentrantReadWriteLock;
import jcifs.CIFSContext;

public class LeaseManager {
    private final ConcurrentHashMap<Smb2LeaseKey, LeaseEntry> leases;

    int added = 0;
    while (added < numElements) {
      // we could rely solely on #poll, but #drainTo might be more efficient when there are multiple
      // elements already available (e.g. LinkedBlockingQueue#drainTo locks only once)
      added += q.drainTo(buffer, numElements - added);
      if (added < numElements) { // not enough elements immediately available; will have to poll
        E e = q.poll(deadline - System.nanoTime(), NANOSECONDS);

    int added = 0;
    while (added < numElements) {
      // we could rely solely on #poll, but #drainTo might be more efficient when there are multiple
      // elements already available (e.g. LinkedBlockingQueue#drainTo locks only once)
      added += q.drainTo(buffer, numElements - added);
      if (added < numElements) { // not enough elements immediately available; will have to poll
        E e = q.poll(deadline - System.nanoTime(), NANOSECONDS);

awkward-to-reproduce situations like 500 errors or slow-loading responses.


### Example

Use MockWebServer the same way that you use mocking frameworks like
[Mockito](https://github.com/mockito/mockito):

1. Script the mocks.
2. Run application code.
3. Verify that the expected requests were made.

Here's a complete example:

### Java
```java
public void test() throws Exception {

    }
}
```

### 4.2 Directory Cache Entry
```java
package jcifs.internal.smb2.lease;

import java.util.concurrent.ConcurrentHashMap;
import java.util.concurrent.locks.ReadWriteLock;
import java.util.concurrent.locks.ReentrantReadWriteLock;

public class DirectoryCacheEntry {
    private final String directoryPath;
    private final Smb2LeaseKey leaseKey;
    private final long createTime;

import java.util.concurrent.ConcurrentHashMap;
import java.util.concurrent.Executors;
import java.util.concurrent.ScheduledExecutorService;
import java.util.concurrent.TimeUnit;
import java.util.concurrent.locks.ReentrantReadWriteLock;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import jcifs.CIFSContext;
import jcifs.internal.smb2.lease.Smb2LeaseKey;

/**

import org.mockito.Mock;
import org.mockito.Mockito;
import org.mockito.junit.jupiter.MockitoExtension;

import jcifs.SmbSession;

/**
 * Tests for SmbTransportInternal interface using Mockito mocks to
 * exercise method contracts, checked exceptions, and interactions.
 */
@ExtendWith(MockitoExtension.class)
public class SmbTransportInternalTest {

    @Mock
    private SmbTransportInternal transport;

      assertLockNotHeld()

      connection.updateConnectionFlowControl(read)
    }

    /**
     * Accept bytes on the connection's reader thread. This function avoids holding locks while it
     * performs blocking reads for the incoming bytes.
     */
    @Throws(IOException::class)
    internal fun receive(
      source: BufferedSource,
      byteCount: Long,
    ) {

これは **FastAPI** が以下のようなボディを期待することを意味します:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

繰り返しになりますが、**FastAPI** を使用して、その宣言を行うだけで以下のような恩恵を受けられます:

            assertEquals(24, encoded);
            assertEquals(flags, SMBUtil.readInt4(buffer, 16));
        }

        @Test
        @DisplayName("Should encode multiple locks sequentially")
        void testSequentialEncoding() {
            Smb2Lock lock1 = new Smb2Lock(100L, 200L, 1);
            Smb2Lock lock2 = new Smb2Lock(300L, 400L, 2);
