AtmosphereResponse (atmosphere-runtime 2.4.5.vaadin2 API)

All Superinterfaces:

javax.servlet.http.HttpServletResponse, javax.servlet.ServletResponse

All Known Implementing Classes:

AtmosphereResponseImpl
```
public interface AtmosphereResponse
extends javax.servlet.http.HttpServletResponse
```
An Atmosphere's response representation. An AtmosphereResponse can be used to construct a bi-directional asynchronous application. If the underlying transport is a WebSocket or if its associated AtmosphereResource has been suspended, this object can be used to write message back to the client at any moment.
This object can delegate the write operation to AsyncIOWriter.

  - write
```
AtmosphereResponse write(byte[] data,
                       boolean writeUsingOriginalResponse)
```
    Write the String by either using the PrintWriter or OutputStream. The decision is based on the request attribute ApplicationConfig.PROPERTY_USE_STREAM. If writeUsingOriginalResponse is set to true, execute the write without invoking the defined AsyncIOWriter.
    
    Parameters:
    data - the bytes to write
    writeUsingOriginalResponse - if true, execute the write without invoking the AsyncIOWriter
  - write
```

                       int length)
```
    Write the bytes by either using the PrintWriter or OutputStream. The decision is based on the request attribute ApplicationConfig.PROPERTY_USE_STREAM.
    
    Parameters:
    data - the bytes to write
    offset - the first byte position to write
    length - the data length
  - write
```
AtmosphereResponse write(byte[] data,
                       int offset,
                       int length,
                       boolean writeUsingOriginalResponse)
```
    Write the String by either using the PrintWriter or OutputStream. The decision is based on the request attribute ApplicationConfig.PROPERTY_USE_STREAM. If writeUsingOriginalResponse is set to true, execute the write without invoking the defined AsyncIOWriter.
    
    Parameters:
    data - the bytes to write
    offset - the first byte position to write
    length - the data length
    writeUsingOriginalResponse - if true, execute the write without invoking the AsyncIOWriter
