RE: Using CreateObject with init correctly

Hi Richard,

To init() on create you need to make sure that the init() method returns THIS 
(cfreturn this /) In your example it seems that you are returning VOID.

Cheers,
Baz

Subject: Using CreateObject with init correctly

I have seen code where an object was created like this:
cfset userInfo=CreateObject(component, 
objects.player).init(REQUEST.id) /

The method I had been using that works is like this:
cfset REQUEST.id = 1 /
cfset userInfo=CreateObject(component, objects.player) /
cfset userInfo.init(datasource) /
cfset REQUEST.qryUserDetails = userInfo.getUserDetails(REQUEST.id) /
cfdump var=#REQUEST.qryUserDetails#cfabort /

I have tried the method of initiating the Object as it is created, but when I 
do I get an error:

cfset userInfo=CreateObject(component, 
objects.player).init(REQUEST.id) /
cfset REQUEST.qryUserDetails = userInfo.getUserDetails(REQUEST.id) /
cfdump var=#REQUEST.qryUserDetails#cfabort /

This fails with the error message, “Variable userInfo is 
undefined.” Would someone clarify how I can do this correctly and what 
would be best practice?

Thank you for your help and opinions,

Richard

here's an example from some code I worked on using the 
jakarta apache Project's HSSp java classes:

cfset wb = 
createObject(java,org.apache.poi.hssf.usermodel.HSSFWorkbook).init()/

this is creating an object that creates an excel 
spreadshhet workbook...

Here's the entire code snippet...

cfset wb = 
createObject(java,org.apache.poi.hssf.usermodel.HSSFWorkbook).init()/
cfset fileOut = 
createObject(java,java.io.FileOutputStream).init(#workbookpath#)/
cfset wb.write(fileOut)/
cfset fileOut.close()/

Re: Using CreateObject with init correctly

2006-01-18 Thread Michael Dinowitz 
The problem is inside your init() method. You're not returning the object in 
the cfreturn.

CFFUNCTION name=Init access=public returntype=CachedQuery 
output=false
  CFARGUMENT name=DSN type=String required=yes
  !--- Set the DSN to the local variables for the CFC ---
  CFSET Variables.DSN=Arguments.DSN
  !--- Return the query object ---
  CFRETURN This
/CFFUNCTION
This is the init method of my cachedquery CFC. Note that I'm setting a 
returntype equal to the name of the CFC, but the entire returntype is not 
needed. The main point is that I'm returning THIS which means I'm returning 
the object back to the call to be stored in the external variable.

Using this call:
CFSET Application.CachedQuery=CreateObject('Component', 
'Components.CachedQuery').Init(DSN)
will call the cachedquery CFC, call the init method, pass it the DSN and 
when the method is done, it'll pass the entire CFC back as the value to be 
assigned to the Application.CachedQuery variable.


I have seen code where an object was created like this:
 cfset userInfo=CreateObject(component, 
 objects.player).init(REQUEST.id) /

 The method I had been using that works is like this:
 cfset REQUEST.id = 1 /
 cfset userInfo=CreateObject(component, objects.player) /
 cfset userInfo.init(datasource) /
 cfset REQUEST.qryUserDetails = userInfo.getUserDetails(REQUEST.id) /
 cfdump var=#REQUEST.qryUserDetails#cfabort /

 I have tried the method of initiating the Object as it is created, but 
 when I do I get an error:

 cfset userInfo=CreateObject(component, 
 objects.player).init(REQUEST.id) /
 cfset REQUEST.qryUserDetails = userInfo.getUserDetails(REQUEST.id) /
 cfdump var=#REQUEST.qryUserDetails#cfabort /

 This fails with the error message, â?oVariable userInfo is undefined.â? 
 Would someone clarify how I can do this correctly and what would be best 
 practice?

 Thank you for your help and opinions,

 Richard

RE: Using CreateObject with init correctly

2006-01-18 Thread Ian Skinner 
Initiating a Java object in the same line as creating it does not work all the 
time.  It depends on how the Java object is coded and how its constructors are 
built.  I ran into this when using the Java file read objects.  When using 
these, one must assign the object with the create object function then init the 
object on a second line.  It just does not work on one line.
