dw.object.CustomAttributes
This class is used together with other classes that contain custom attributes and is used to read and write these attributes. The actual attributes are accessible as ECMA properties. The syntax for setting and retrieving the value of a custom attribute depends upon the type of the attribute. If the wrong syntax is used to set an individual attribute than an exception will be thrown.

The following script examples demonstrate how to work with custom attributes. Suppose we have an ExtensibleObject named "eo" possessing attributes of all the different types supported by the Commerce Cloud Digital metadata system. The following script snippet shows that setting single-valued attributes is simply a matter of using the assignment operator and standard ECMA primitives and built-in types:

 // attribute of value type 'Boolean'
 eo.custom.bvalue = true;
 var b : Boolean = eo.custom.bvalue;

 // attribute of value type 'Integer'
 eo.custom.ivalue = 10;
 var i : Number = eo.custom.ivalue;

 // attribute of value type 'Number'
 eo.custom.dvalue = 99.99;
 var d : Number = eo.custom.dvalue;

 // attribute of value type 'String'
 eo.custom.svalue = "String1";
 var s : String = eo.custom.svalue;

 // attribute of value type 'Email'
 eo.custom.emailvalue = "[email protected]";
 var e : String = eo.custom.emailvalue;

 // attribute of value type 'Text'
 eo.custom.tvalue = "laaaaaaaaaaaarge text";
 var t : String = eo.custom.tvalue;

 // attribute of value type 'Date'
 eo.custom.dtvalue = new Date;
 var date : Date = eo.custom.dtvalue;
 

Setting and retrieving the values for multi-value attributes is also straightforward and uses ECMA arrays to represent the multiple values. Set-of attributes and enum-of attributes are handled in a very similar manner. The chief difference is that enum-of attributes are limited to a prescribed set of value definitions whereas set-of attributes are open-ended. Furthermore, each value in an enum-of attribute has a value and a display name which affects the retrieval logic. Multi-value attributes are returned as an array. This array is read-only and can't be used to update the multi-value attribute. To update the multi-value attribute an array with new values must be assigned to the attribute.

 // attribute of value type 'Set of String'
 // set the attribute value only if it hasn't been already set
 if( !('setofstringvalue' in eo.custom) )
 {
     eo.custom.setofstringvalue = new Array("abc","def","ghi");
 }

 // returns an Array of String instances
 var setofstring : Array = eo.custom.setofstringvalue;
 var s1 : String = setofstring[0];
 var s2 : String = setofstring[1];
 var s3 : String = setofstring[2];

 // attribute of value type 'Enum of Integer' with multi-value handling
 eo.custom.enumofintmultivalue = new Array(1, 2, 3);

 // returns an Array of EnumValue instances
 var enumofintmulti : Array = eo.custom.enumofintmultivalue;
 var value1 : Number = enumofintmulti[0].getValue();
 var displayvalue1 : String = enumofintmulti[0].getDisplayValue();
 var value2 : Number = enumofintmulti[1].getValue();
 var displayvalue2 : String = enumofintmulti[1].getDisplayValue();
 var value3 : Number = enumofintmulti[2].getValue();
 var displayvalue3 : String = enumofintmulti[2].getDisplayValue();
