exception:
  IOException - if an input/output error occurs



getConnector
public Connector getConnector()(Code)
Return the Connector through which this Response is returned.



getContentCount
public int getContentCount()(Code)
Return the number of bytes actually written to the output stream.



getContentLength
public int getContentLength()(Code)
Return the content length that was set or calculated for this Response.



getContentType
public String getContentType()(Code)
Return the content type that was set or calculated for this response, or null if no content type was set.



getContext
public Context getContext()(Code)
Return the Context with which this Response is associated.



getIncluded
public boolean getIncluded()(Code)
Return the "processing inside an include" flag.



getInfo
public String getInfo()(Code)

getReporter
public PrintWriter getReporter() throws IOException(Code)
Return a PrintWriter that can be used to render error messages, regardless of whether a stream or writer has already been acquired. Writer which can be used for error reports.

isAppCommitted
public boolean isAppCommitted()(Code)
Application commit flag accessor.



isError
public boolean isError()(Code)
Error flag accessor.



isSuspended
public boolean isSuspended()(Code)
Suspended flag accessor.



recycle
