sendRequest

public void sendRequest(RequestChannel requestChannel,
                        HttpContext httpContext)
                 throws HttpException,
                        IOException

从接口复制的说明: AsyncRequestProducer

Triggered to signal the ability of the underlying request channel to accept a request messages. The data producer can choose to send a request message immediately inside the call or asynchronously at some later point.

指定者:

sendRequest 在接口中 AsyncRequestProducer

参数:

requestChannel - the request channel capable to accepting a request message.

httpContext - the actual execution context.

抛出:

HttpException

IOException

available

public int available()

从接口复制的说明: AsyncDataProducer

Returns the number of bytes immediately available for output. This method can be used as a hint to control output events of the underlying I/O session.

指定者:

available 在接口中 AsyncDataProducer

返回:

the number of bytes immediately available for output

produce

public void produce(DataStreamChannel channel)
             throws IOException

从接口复制的说明: AsyncDataProducer

Triggered to signal the ability of the underlying data channel to accept more data. The data producer can choose to write data immediately inside the call or asynchronously at some later point.

指定者:

produce 在接口中 AsyncDataProducer

参数:

channel - the data channel capable to accepting more data.

抛出:

IOException

isRepeatable

public boolean isRepeatable()

从接口复制的说明: AsyncRequestProducer

Determines whether the producer can consistently produce the same content after invocation of ResourceHolder.releaseResources().

指定者:

isRepeatable 在接口中 AsyncRequestProducer

failed

public void failed(Exception cause)

从接口复制的说明: AsyncRequestProducer

Triggered to signal a failure in data generation.

指定者:

failed 在接口中 AsyncRequestProducer

参数:

cause - the cause of the failure.

releaseResources

public void releaseResources()

指定者:

releaseResources 在接口中 ResourceHolder
