Class Structure

                                                                            Class & Data Model

Data Model

·         A property is nothing but a variable which can be used to hold the data.

·         Every property rule describes the property name type of data it is modelling.

·         The property rule is an instance of Rule-object-property

·         The property will be created and saved in a class.While creating the new property we should specify the name of the class towhom the property belongs to.

·         How to create the model:Go to technical : Model-> RC -> New

Property Modes:                 

·         The property mode used to specify that the property is going to hold single/ mul values.

·         The most commonly used property modes are :

Single value:It takes only single value

Value List:Allows multiple values with single data type & it is an ordered list, it will act like array(1)

Value Group: Allows multiple values, It is unordered List

Page: Allows multiple properties of difference data types& a page is reference of a class

Page List:Allows multiple values with multiple properties.  It is ordered list.

Page group:Allowsmultiplevalues with multiple data types. It is unordered list.

Property types: This input field can be used to specify the data the property can be used.

                               The property types are: Text,integer,double, Date time

HTML property: It is used to change the appearance of property when displaying it.

Table type: It can be used to specify the list of data or the list of values, can be selected for the given property but the property can be hold only one value at a time

Creating multiple properties:To create multiple properties we need to use define property wizard.

                Go to data model -> RC ->define property

Model Rule:

·         Model rules can be used to initialize the properties with values for the instances of a class.

·         Model rules works similar as constructers in java. Model rules are part of technical category.

pyDefault:

·         If the model name is given as “pyDefault” then the model will be called automatically when creating instances for those classes.

·         While creating the model rule,“if call super class model” check box is selected then the system initializes the property given in super class model first.

·         The model rules can be referred in activity, starter flow rules, service rules, connecter rules.

·         When creating the model rule we need to specify applist to parameters & the model name.

How to create data table:Go to PEGA logo ->Data model ->Tables ->“click on Add new Table”.

While creating the table we need to specify the following parameters.

Ø  Class name (specify the name of the class to which the table has to be associated)

Ø  Then derives from “Data-“ to make the given class as Data class.

Property:Specify the list of the property that you want to make them as a part of data tables

Ø  While creating the data table PRPC creates 5 associated rules. They are:

pyDefault, list, edit list, validate, data table class editor.

Creating embeddedproperties:

·         Toembed the properties of one class in other class select the class that you want embed and include that class in another class as a page.

·         To include it as a page we also need to specify the class name.

Check in & Check Out:

·         Check in & check out functionality can used to allow users to modify or not modify the rules

·         If the rule is checked in status than the user can do the check out and modify the rules.

·         The save icon is disabled when rule is checked in status.

·         If the rule is checked out by one user then the remaining users will not be allowed to the modify rule until the user do the check in of the same rule.
