3 Execute one or more actions on the object.
Note: Unlike the corresponding tags, you cannot use application-specific parameters in these functions. You can only use
the parameters that ColdFusion supports directly.
Step 1: Instantiate a service object
To create a function object, such as a mail object, use the
following example:
myMail = new mail(server="sendmail.myCo.com");
Step 2a: Managing attributes
You can set attributes in several ways:
• As name=value parameters to the object initializer when you instantiate the object, as in the following example.
myMail = new mail(server="sendmail.myCo.com");
• As name=value parameters to an object action method, as in the following example:
Q = myQuery.execute(sql="select * from art");
• By using attribute setters, as in the following example:
myMail.setSubject("Hi");
Note: You cannot use a
getAttributeName
Instead, use
GetAttributes(AttributeName)
• By using the following functions:
SetAttributes(attrib1=value,attrib2=value,...);
GetAttributes([attribName1[,attribName2]]....);
ClearAttributes([attribName1[,attribName2]]...);
Note: If you specify a result attribute for a stored procedure, then calling
executionTime,statusCode,cached
and
executionTime statusCode
Step 2b: Managing child tag operations
All service objects correspond to tags that have child tags. For example,
child tags.
To specify the child tag functionality, use the following methods:
•
httpObj.addParam
•
mailObj.addParam
•
mailObj.addPart
•
pdfObj.addParam
•
queryObj.addParam
•
storedProcObj.addParam
•
storedProcObj.addProcResult
For example:
operator or
new
function to get the value of the attribute specified by AttributeName.

. If you do not specify a result attribute,
