Collection classes X++, Maps , list

 

Class	Description	Data types	Access
List	Values stored sequentially with ability to add values at the beginning or end of the list	All values must be the same data type	Use ListIterator or ListEnumerator
Set	Values stored non-sequentially. Duplicates are not added to the set.	All values must be the same data type	Use SetIterator or SetEnumerator
Map	Values stored by using a unique key.	The key and the value need not be from the same data type.	Use MapIterator or MapEnumerator
Struct	Values stored by using a unique string as a key	The key must be a string. The values can be of any type.	Provide the string key to the value method

Set Class examples

  Set coffeeReceiptSet = new Set(Types::String);

  if(coffeeReceiptSet.in(weightView.BFSIndependentWeighID))

  {

      continue;

  }

  else

  {

      coffeeReceiptSet.add(weightView.BFSIndependentWeighID);

  }

Map class examples 

Map  openTransMap = new Map(Types::Int64, Types::Real);

  if (!openTransMap.exists(SpecTransNew.OpenTransRecId))

  {

      openTransMap.insert(SpecTransNew.OpenTransRecId, SpecTransNew.DebitNoteAmt);

  }

  else

  {

      openTransMap.insert(SpecTransNew.OpenTransRecId,                         openTransMap.lookup(SpecTransNew.OpenTransRecId) + SpecTransNew.DebitNoteAmt);

  }

MapEnumerator mapEnumerator = openTransMap.getEnumerator();

  while (mapEnumerator.moveNext())

  {

      mapRecId       = mapEnumerator.currentKey();

      mapAmt         = mapEnumerator.currentValue();

}

Container class examples

 container               attributesCon = conIns(attributesCon,noSampleRecords,contractLine.recid);

 for (i = 1; i<=conLen(attributesCon); i++)

 {

     

    

     attributesChildCon = conPeek(attributesCon, i);

}
