Package org.glassfish.grizzly

Interface Reader<L>

Type Parameters:

L - the reader address type

All Known Subinterfaces:

AsyncQueueReader<L>

All Known Implementing Classes:

AbstractNIOAsyncQueueReader, AbstractReader, TCPNIOAsyncQueueReader, TCPNIOTemporarySelectorReader, TemporarySelectorReader, UDPNIOAsyncQueueReader, UDPNIOTemporarySelectorReader

public interface Reader<L>

Implementations of this interface are able to read data from Connection to a Buffer. There are two basic Reader implementations in Grizzly: AsyncQueueReader, TemporarySelectorReader.

Method Details

read

GrizzlyFuture<ReadResult<Buffer,L>> read(Connection<L> connection)

Method reads data.

Parameters:

connection - the Connection to read from

Returns:

Future, using which it's possible to check the result

read

GrizzlyFuture<ReadResult<Buffer,L>> read(Connection<L> connection,
 Buffer buffer)

Method reads data to the buffer.

Parameters:

connection - the Connection to read from

buffer - the buffer, where data will be read

Returns:

Future, using which it's possible to check the result

read

void read(Connection<L> connection,
 Buffer buffer,
 CompletionHandler<ReadResult<Buffer,L>> completionHandler)

Method reads data to the buffer.

Parameters:

connection - the Connection to read from

buffer - the buffer, where data will be read

completionHandler - CompletionHandler, which will get notified, when read will be completed

read

void read(Connection<L> connection,
 Buffer buffer,
 CompletionHandler<ReadResult<Buffer,L>> completionHandler,
 Interceptor<ReadResult> interceptor)

Method reads data to the buffer.

Parameters:

connection - the Connection to read from

buffer - the Buffer to which data will be read

completionHandler - CompletionHandler, which will get notified, when read will be completed

interceptor - Interceptor, which will be able to intercept control each time new portion of a data was read to a buffer. The interceptor can decide, whether asynchronous read is completed or not, or provide other processing instructions.
