- Method Detail
  - shouldRegisterReadEvent
```
boolean shouldRegisterReadEvent()
```
    Used to determine if the Connection should register with the TransportManager Selector to handle read events. For example, an HTTP transport would not register since the requesting thread would just block on read when waiting for the reply.
    
    Returns:
    
    true if it should be registered.
  - shouldRegisterServerReadEvent
```
boolean shouldRegisterServerReadEvent()
```
    Used to determine if the Connection should register with the TransportManager Selector to handle read events. For example, an HTTP transport would not register since the requesting thread would just block on read when waiting for the reply.
    
    Returns:
    
    true if it should be registered.
  - read
```
boolean read()
```
    Called to read incoming messages.
    
    Returns:
    
    true if the thread calling read can be released.
  - close
```
void close()
```
    Close the Connection.
  - getAcceptor
```
Acceptor getAcceptor()
```
    Get the Acceptor that created this Connection.
    
    Returns:
    
    Acceptor
  - getContactInfo
```
ContactInfo getContactInfo()
```
    Get the ContactInfo that created this Connection .
    
    Returns:
    
    ContactInfo
  - getEventHandler
```
EventHandler getEventHandler()
```
    Get the EventHandler associated with this Acceptor.
    
    Returns:
    
    EventHandler
  - isServer
```
boolean isServer()
```
    Indicates whether a ContactInfo or a Acceptor created the Connection.
    
    Returns:
    
    true if Connection an Acceptor created the Connection.
  - isBusy
```
boolean isBusy()
```
    Indicates if the Connection is in the process of sending or receiving a message.
    
    Returns:
    
    true if the Connection is busy.
  - getTimeStamp
```
long getTimeStamp()
```
    Timestamps are used for connection management, in particular, for reclaiming idle Connections.
    
    Returns:
    
    the "time" the Connection was last used.
  - setTimeStamp
```
void setTimeStamp(long time)
```
    Timestamps are used for connection management, in particular, for reclaiming idle Connections.
    
    Parameters:
    
    time - - the "time" the Connection was last used.
  - setState
```
void setState(String state)
```
    The "state" of the Connection. param state
  - writeLock
```
void writeLock()
```
    Grab a write lock on the Connection. If another thread already has a write lock then the calling thread will block until the lock is released. The calling thread must call writeUnlock() when it is done.
  - writeUnlock
```
void writeUnlock()
```
    Release a write lock on the Connection.
  - sendWithoutLock
```
void sendWithoutLock(OutputObject outputObject)
```
  - registerWaiter
```
void registerWaiter(MessageMediator messageMediator)
```
    Register an invocation's MessageMediator with the Connection. This is useful in protocols which support fragmentation.
    
    Parameters:
    
    messageMediator -
  - waitForResponse
```
InputObject waitForResponse(MessageMediator messageMediator)
```
    If a message expect's a response then this method is called. This method might block on a read (e.g., HTTP), put the calling thread to sleep while another thread read's the response (e.g., GIOP), or it may use the calling thread to perform the server-side work (e.g., Solaris Doors).
    
    Parameters:
    
    messageMediator -
  - unregisterWaiter
```
void unregisterWaiter(MessageMediator messageMediator)
```
    Unregister an invocation's MessageMediator with the Connection.
    
    Parameters:
    
    messageMediator -
  - setConnectionCache
```
void setConnectionCache(ConnectionCache connectionCache)
```
  - getConnectionCache
```
ConnectionCache getConnectionCache()
```
