Class ScriptEvent

java.lang.Object
  extended by com.dynamide.DynamideObject
      extended by com.dynamide.event.ScriptEvent
All Implemented Interfaces:
IGet, java.io.Serializable

public class ScriptEvent
extends DynamideObject
implements java.io.Serializable

In order to make this class as easy to use as possible from multiple scripting languages supported by events, the important fields are available as public fields and as bean properties with proper getters and setters. That is, foo, getFoo() and setFoo() are all public.

static int RA_DEFAULT
          This is the default value, which means dynamide will continue with the default loading of pages according to other page order rules, such as calling onQueryNextPage.
static int RA_JUMP_TO_PAGE
          Use this value for resultAction to jump directly to the page named by nextPageID.
static int RA_RETURN_SOURCE
          If your event generates html/xml and you wish to return exactly the source you generate, set the resultAction to this value, and set the resultSrc to the source.

Field Detail

RA_DEFAULT

public static final int RA_DEFAULT
This is the default value, which means dynamide will continue with the default loading of pages according to other page order rules, such as calling onQueryNextPage.

Constant Field Values

RA_SHOW_ERRORS

public static final int RA_SHOW_ERRORS
Use this value for resultAction to re-show the current page, but with errors flagged. You can set field errors with Field.setError(boolean) and Field.setErrorMessage(String). If you set any errors, the page will automatically be reshown. Clear them to move on, using Widget.clearErrorMessage() or Widget.setErrorMessage(null).

See Also:
Constant Field Values

RA_JUMP_TO_PAGE

public static final int RA_JUMP_TO_PAGE
Use this value for resultAction to jump directly to the page named by nextPageID.

See Also:
Constant Field Values

RA_RETURN_SOURCE

public static final int RA_RETURN_SOURCE
If your event generates html/xml and you wish to return exactly the source you generate, set the resultAction to this value, and set the resultSrc to the source.

See Also:
Constant Field Values

RA_THROW_EXCEPTION

public static final int RA_THROW_EXCEPTION
If your event would like to throw an exception to be caught by the error page, you should set resultAction to RA_THROW_EXCEPTION, and set the outputObject to the exception, otherwise dynamide catches all ScriptEvent exceptions, and handles them a little differently, though in most cases you'll end up with the error page anyway.

See Also:
Constant Field Values

RA_SEND_REDIRECT

public static final int RA_SEND_REDIRECT
Use this value for resultAction to send the client's web browser to a URL. This is useful for clearing the POST parameters from the client, so that they don't get re-submitted when the client does a refresh in the browser (e.g. Ctrl-R).

ScriptEvent

public ScriptEvent(DynamideObject owner)
Method Detail

finalize

public void finalize()
              throws java.lang.Throwable
Overrides:
finalize in class DynamideObject
Throws:
java.lang.Throwable

getResultAction

public int getResultAction()

setResultAction

public void setResultAction(int new_value)

printResultAction

public java.lang.String printResultAction()

sendRedirect

public void sendRedirect(java.lang.String url)
Send the client a redirect, rather than a rendered page, to avoid POST data being re-posted on a refresh.


sendRedirectToPage

public void sendRedirectToPage(java.lang.String pageID)
Send the client a redirect, to the named page, using the current SESSIONID and applicationPath.


sendRedirectToPage

public void sendRedirectToPage(java.lang.String pageID,
                               java.lang.String theAction)
Send the client a redirect, to the named page, using the current SESSIONID and applicationPath, and the supplied action parameter.
 sendRedirectToPage("page1", "display");
 

Parameters:
theAction - contains a single string value that is the action to be sent to the application_onAction or {pageID}_onAction event.

sendRedirectToPage

public void sendRedirectToPage(java.lang.String pageID,
                               java.lang.String action,
                               java.lang.String moreParams)
Send the client a redirect, to the named page, using the current SESSIONID and applicationPath, and the supplied action parameter, but allowing additional parameters to be sent.

Parameters:
action - contains a single string value that is the action to be sent to the application_onAction or {pageID}_onAction event.
moreParams - contains name-value pairs URL encoded. Here are some examples:
 sendRedirectToPage("page1", "display", "category=sales");
 sendRedirectToPage("page1", "display", "topic=My+Preferences");
 
Note that you typically do not send additional parameters, since these would best be set in the Session as Fields before leaving the current event. If you need to send a redirect to another web site or application, use sendRedirect(String url).

jumpToPage

public void jumpToPage(java.lang.String nextPageID)
Sets the event resultAction to ..., and sets the resultSrc property, but the action will occur when the event returns. @return an empty String, just so you can follow this style in events if you like:
   if (condition){
      return event.jumpToPage("page1");
   }
  
Rather than:
   if (condition){
      event.jumpToPage("page1");
      return;
   }
  
Both styles will work, and are exactly equivalent, but the first is easier to read.


returnSource

public void returnSource(java.lang.String src,
                         boolean prettyPrint)
Sets the event resultAction to RA_RETURN_SOURCE, and sets the resultSrc property, but the action will occur when the event returns.


returnSource

public void returnSource(java.lang.String src)

returnError

public void returnError(java.lang.String error,
                        java.lang.Throwable t)
Sets the event resultCode RC_ERROR, the action will occur when the event returns.

Parameters:
t - can be null.

setResultsFrom

public ScriptEvent setResultsFrom(ScriptEvent other)
Sets all results from the ScriptEvent passed in, so that you can chain events. Does not copy references to inputObject or outputObject. Example usage:
  ScriptEvent res = event.setResultsFrom(widget.fireEvent(inputObject, "onClick");
