DataflowStreamReadAdapter (gpars 1.2.1)

java.lang.Object
- groovyx.gpars.dataflow.stream.DataflowStreamReadAdapter<T>

Type Parameters:
T - The type of messages to pass through the stream

All Implemented Interfaces:

DataflowReadChannel<T>, SelectableChannel<T>

Direct Known Subclasses:

SyncDataflowStreamReadAdapter
```
public class DataflowStreamReadAdapter<T>
extends java.lang.Object
implements DataflowReadChannel<T>
```
Adapts a DataflowStream to accommodate for the DataflowReadChannel interface. To minimize the overhead and stay in-line with the DataflowStream semantics, the DataflowStreamReadAdapter class is not thread-safe and should only be used from within a single thread. If multiple threads need to read from a DataflowStream, they should each create their own wrapping DataflowStreamReadAdapter.

    Specified by:
    
    getVal in interface DataflowReadChannel<T>

  - getValAsync
```
public void getValAsync(MessageStream callback)
```
    Description copied from interface: DataflowReadChannel
    
    Asynchronously retrieves the value from the channel. Sends the actual value of the channel as a message back the the supplied actor once the value has been bound. The actor can perform other activities or release a thread back to the pool by calling react() waiting for the message with the value of the Dataflow channel.
    
    Specified by:
    
    getValAsync in interface DataflowReadChannel<T>
    
    Parameters:
    callback - An actor to send the bound value to.
  - getValAsync
```
public void getValAsync(java.lang.Object attachment,
               MessageStream callback)
```
    Description copied from interface: DataflowReadChannel
    
    Asynchronously retrieves the value from the channel. Sends a message back the the supplied MessageStream with a map holding the supplied attachment under the 'attachment' key and the actual value of the channel under the 'result' key once the value has been bound. Attachment is an arbitrary value helping the actor.operator match its request with the reply. The actor/operator can perform other activities or release a thread back to the pool by calling react() waiting for the message with the value of the Dataflow channel.
    
    Specified by:
    
    getValAsync in interface DataflowReadChannel<T>
    
    Parameters:
    attachment - arbitrary non-null attachment if reader needs better identification of result
    callback - An actor to send the bound value plus the supplied index to.

    separate in interface DataflowReadChannel<T>
    
    Parameters:
    params - Additional parameters to initialize the operator with (e.g. listeners or maxForks)
    outputs - The channels to send data to.
    code - A closure returning a list of values to pass to the output channels. Values are output to the output channels with identical index.
