方法详细资料

register

public void register(org.eclipse.jetty.util.Callback callback)
              throws ReadPendingException

Call to register interest in a callback when a read is possible. The callback will be called either immediately if needsFillInterest() returns true or eventually once fillable() is called.

参数:

callback - the callback to register

抛出:

ReadPendingException - if unable to read due to pending read op

tryRegister

public boolean tryRegister(org.eclipse.jetty.util.Callback callback)

Call to register interest in a callback when a read is possible. The callback will be called either immediately if needsFillInterest() returns true or eventually once fillable() is called.

参数:

callback - the callback to register

返回:

true if the register succeeded

fillable

public void fillable()

Call to signal that a read is now possible.

isInterested

public boolean isInterested()

返回:

True if a read callback has been registered

getCallbackInvocationType

public org.eclipse.jetty.util.thread.Invocable.InvocationType getCallbackInvocationType()

onFail

public boolean onFail(Throwable cause)

Call to signal a failure to a registered interest

参数:

cause - the cause of the failure

返回:

true if the cause was passed to a Callback instance

onClose

public void onClose()

toString

public String toString()

覆盖:

toString 在类中 Object

toStateString

public String toStateString()

needsFillInterest

protected abstract void needsFillInterest()
                                   throws IOException

Register the read interest Abstract method to be implemented by the Specific ReadInterest to schedule a future call to fillable() or onFail(Throwable)

抛出:

IOException - if unable to fulfill interest in fill
