How to create field validation class which extends MAXTableDomain

1. Write a custom field validation class and extend MAXTableDomain. (import psdi.mbo.MAXTableDomain)
2. Create a constructor and set a relationship with Object (table name).
3. Set a list criteria in the constructor itself (where clause for the above object).
4. If you would like to filter with more where clauses then write a getList() method.
5. Associate this field validation class to attribute in DB Configuration. And make sure that domain is not associated to this attribute.
Sample Class:
public class CustomFeildClass extend MAXTableDomain
{

public CustomFeildClass (MboValue mbv) throws RemoteException
 {
super(mbv);

String thisAttrName = getMboValue().getAttributeName();

setRelationship("FAILURELIST","failurecode=:"+ thisAttrName)

// Note: Here FAILURELIST is a Object. Most of the developers will confuse that it is a relationship name.

 

setListCriteria("parent is null");
//Note: this sets a where condition for the above object.

setErrorMessage("asset","failurecode");

 

 }

public MboSetRemote getList() throws MXException, RemoteException
 {

String additionalWhere ="orgid=:orgid";

setListCriteria(additionalWhere);
//Note: this sets additional where conditional to display when user clicks on lookup.

}
}

 

How to create custom condition class

There are two types of Conditions in Condition Expression Manager:
1. Expression
2. Class


To use Type Class in Condition, need to create a custom condition class.
1. Create a custom condition class which implements CustomCondition interface.
eg:
public class ConditionClass implements CustomCondition {

public boolean evaluateCondition(MboRemote mbo, Object param)throws MXException, RemoteException

if(<business logic>)

{

<business logic>
return true;

}
else{
<business logic>
return false
}

}
public String toWhereClause(Object parm, MboSetRemote msr)throws MXException, RemoteException

{

<business logic>

 return <sql>
}

}

2. CustomCondition interface have two methods:
a. evaluateCondition(MboRemote mbo, Object param): this method is used to evaluate condition and returns either true or false based on the business logic written in it. This return boolean value.

 b.toWhereClause(Object parm, MboSetRemote msr) : This method is used to return sql to the object which this condition is applied.This returns String.
