org.directwebremoting.dwrp.BaseScriptConduit
org.directwebremoting.dwrp.HtmlScriptConduit
public class HtmlScriptConduit
A ScriptConduit for use with HTML/SCRIPT wrapped Javascript output.
Scripts begin with an html and script tags. The scripts have been altered to include an 'execute-in-parent-context' wrapper.
If this conduit is used, the output should be directed to an iframe. No polling should be required.
This conduit works with IE 6/7 since the 4k buffer drawback (see
PlainScriptConduit
and Html4kScriptConduit
does not prevent
the execution of script elements.

public void beginStream()
BaseScriptConduit
This method is always called exactly once in the lifetime of a
conduit, after #preStreamSetup()
and before any scripts are sent.
public void endStream()
BaseScriptConduit
This method is always called exactly once in the lifetime of a conduit, just before the stream is closed.
public boolean addScript(ScriptBuffer scriptBuffer) throws java.io.IOException, MarshallException
ScriptConduit
It is not an error to refuse to handle the script and return false, it
just indicates that this ScriptConduit did not accept the script.
If the ScriptConduit can no longer function then it should throw an
exception and it will be asumed to be no longer useful.
If you want to implement this method then you will probably be doing
something like calling ServletOutputStream.print(String)
and
passing in the results of calling ScriptBufferUtil.createOutput().
addScript
in class ScriptConduit
scriptBuffer
- The script to execute
java.io.IOException
- If this conduit is broken and should not be used
MarshallException
- If objects in the script can not be marshalled
