Method Detail

close

public void close()

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface java.io.Closeable

Since:

4.2

finish

@Deprecated
public void finish()

Deprecated.

(4.2) use close()

Notification that any resources allocated for writing can be released.

Specified by:

finish in interface ProducingNHttpEntity

produceContent

public void produceContent(ContentEncoder encoder,
                           IOControl ioctrl)
                    throws java.io.IOException

Description copied from interface: HttpAsyncContentProducer

Invoked to write out a chunk of content to the ContentEncoder. The IOControl interface can be used to suspend output event notifications if the entity is temporarily unable to produce more content.

When all content is finished, the producer MUST call ContentEncoder.complete(). Failure to do so may cause the entity to be incorrectly delimited.

Please note that the ContentEncoder object is not thread-safe and should only be used within the context of this method call. The IOControl object can be shared and used on other thread to resume output event notifications when more content is made available.

Specified by:

produceContent in interface HttpAsyncContentProducer

Specified by:

produceContent in interface ProducingNHttpEntity

Parameters:

encoder - content encoder.

ioctrl - I/O control of the underlying connection.

Throws:

java.io.IOException

getContentLength

public long getContentLength()

Specified by:

getContentLength in interface HttpEntity

isRepeatable

public boolean isRepeatable()

Description copied from interface: HttpAsyncContentProducer

Determines whether or not this producer is capable of producing its content more than once. Repeatable content producers are expected to be able to recreate their content even after having been closed.

Specified by:

isRepeatable in interface HttpAsyncContentProducer

Specified by:

isRepeatable in interface HttpEntity

isStreaming

public boolean isStreaming()

Specified by:

isStreaming in interface HttpEntity

getContent

public java.io.InputStream getContent()

Specified by:

getContent in interface HttpEntity

writeTo

public void writeTo(java.io.OutputStream outstream)
             throws java.io.IOException

Specified by:

writeTo in interface HttpEntity

Throws:

java.io.IOException
