Constructor and Description |
---|
EncoderEmbedder(ChannelBufferFactory bufferFactory,
ChannelDownstreamHandler... handlers)
Creates a new embedder whose pipeline is composed of the specified
handlers.

boolean |
finish()
Signals the pipeline that the encoding or decoding has been finished and
no more data will be offered.
|
protected Channel |
getChannel()
Returns the virtual
Channel which will be used as a mock
during encoding and decoding. |
ChannelPipeline |
getPipeline()
Returns the
ChannelPipeline that handles the input. |

|
boolean |
offer(Object input)
Offers an input object to the pipeline of this embedder.
|
E |
peek()
Reads an encoded or decoded output from the head of the product queue.
|
E |
poll()
Consumes an encoded or decoded output from the product queue.
|
Object[] |
pollAll()
