Question

I want to parse idKeys1 and get the Attribute ID(Pds AttributeId) and Attribute Value(value) from idKeys1. I am not sure what’s the best way to parse it as it’s a list of PDSAttribute.

List<PdsAttribute> idKeys1 = m_pdssmartclient.release(PersistenceEnum.COMMIT, false);
Iterator<PdsAttribute> i = idKeys1.iterator();
  while (i.hasNext()) {
                    String parse = String.valueOf(i.next());
                    System.out.println(i.next());
                      }

Sample Output of idKeys1 is:-

[Pds Attribute: 
Pds AttributeId = 20000
value = 0
Attribute Status = 
Status Code = 0
Status = NOT_PROCESSED
Status message = null

, Pds Attribute: 
Pds AttributeId = 20002
value = -1
Attribute Status = 
Status Code = 0
Status = NOT_PROCESSED
Status message = null

, Pds Attribute: 
Pds AttributeId = 20004
value = -9223372036854775808
Attribute Status = 
Status Code = 0
Status = SUCCESS
Status message = null

, Pds Attribute: 
Pds AttributeId = 248
value = 1906e3551370af60d5b48854fffffffe
Attribute Status = 
Status Code = 0
Status = NOT_PROCESSED
Status message = null

, Pds Attribute: 
Pds AttributeId = 330
value = null
Attribute Status = 
Status Code = 0
Status = NOT_PROCESSED
Status message = null

, Pds Attribute: 
Pds AttributeId = 202
value = 1906e1611370af60d5b48854ffffffff
Attribute Status = 
Status Code = 0
Status = SUCCESS
Status message = null

, Pds Attribute: 
Pds AttributeId = 331
value = null
Attribute Status = 
Status Code = 0
Status = NOT_PROCESSED
Status message = null

, Pds Attribute: 
Pds AttributeId = 347
value = 1906e5a11370af60d5b48854fffffffd
Attribute Status = 
Status Code = 0
Status = NOT_PROCESSED
Status message = null

, Pds Attribute: 
Pds AttributeId = 332
value = 4fa813bc.0.1.8.9.5.0.1
Attribute Status = 
Status Code = 0
Status = NOT_PROCESSED
Status message = null

, Pds Attribute: 
Pds AttributeId = 12
value = 1002491107
Attribute Status = 
Status Code = 0
Status = NOT_PROCESSED
Status message = null

, Pds Attribute: 
Pds AttributeId = 333
value = 4fa813bc.0.1.7.8.0.0.1
Attribute Status = 
Status Code = 0
Status = NOT_PROCESSED
Status message = null

Answer 1

So whats wrong with

        while (i.hasNext()) {
            PdsAttribute attr = (PdsAttribute) (i.next());
            String attrId = String.valueOf(attr.getAttributeId);
            String attrValue = String.valueOf(attr.getValue());
        }

This of course, assumes you have appropriate accessors for the PdsAttributeId and value in your PdsAttribute class. If it doesn’t, you should really consider adding some to encapsulate its members.
