  - findSession
```
InternalSession findSession(String id)
```
    Return the active Session, associated with this Manager, with the specified session id (if any); otherwise return null.
    
    参数:
    id - The session id for the session to be returned
    
    抛出:
    
    IllegalStateException - if a new session cannot be instantiated for any reason
    
    IOException - if an input/output error occurs while processing this request
  - createSession
```
InternalSession createSession(String sessionId)
```
    Construct and return a new session object, based on the default settings specified by this Manager's properties. The session id specified will be used as the session id. If a new session cannot be created for any reason, return null.
    
    参数:
    sessionId - The session id which should be used to create the new session; if null, a new session id will be generated
    
    抛出:
    
    IllegalStateException - if a new session cannot be instantiated for any reason
  - remove
```
void remove(InternalSession session)
```
    Remove this Session from the active Sessions for this Manager.
    
    参数:
    session - Session to be removed
  - remove
```
void remove(InternalSession session,
          boolean update)
```
    Remove this Session from the active Sessions for this Manager.
    
    参数:
    session - Session to be removed
    update - Should the expiration statistics be updated
  - add
```
void add(InternalSession session)
```
    Add this Session to the set of active Sessions for this Manager.
    
    参数:
    session - Session to be added
  - getActiveSessions
```
int getActiveSessions()
```
    Returns the number of active sessions
    
    返回:
    number of sessions active
  - createEmptySession
```
InternalSession createEmptySession()
```
    Get a session from the recycled ones or create a new empty one. The PersistentManager manager does not need to create session data because it reads it from the Store.
  - findSessions
```
InternalSession[] findSessions()
```
  - backgroundProcess
```
void backgroundProcess()
```
    Implements the Manager interface, direct call to processExpires
  - setMaxInactiveInterval
```
void setMaxInactiveInterval(int interval)
```
    Set the default maximum inactive interval (in seconds) for Sessions created by this Manager.
    
    参数:
    interval - The new default value
  - setProcessExpiresFrequency
```
void setProcessExpiresFrequency(int processExpiresFrequency)
```
```
 Set the manager checks frequency.
 设置每尝试多少次清理过期session，才真的会执行一次清理动作
 要和setBackgroundProcessorDelay(int)联合起来看
 如果把这个数字设置为6（默认），那么就是说manager要等待 6 * backgroundProcessorDay的时间才会清理过期session
 
```
    参数:
    processExpiresFrequency - the new manager checks frequency
  - setBackgroundProcessorDelay
```
void setBackgroundProcessorDelay(int backgroundProcessorDelay)
```
```
 Set the manager background processor delay
 设置manager sleep几秒，尝试执行一次background操作（清理过期session）
 
```
    参数:
    backgroundProcessorDelay -
  - setMaxActiveSessions
```
void setMaxActiveSessions(int max)
```
    Set the maximum number of active Sessions allowed, or -1 for no limit. 设置最大活跃session数，默认无限
    
    参数:
    max - The new maximum number of sessions
