xpfGetAttrsHashedValue

xpfGetAttrsHashedValue (hashTableIndex, index               : INTEGER;
                        attr1Value, attr2Value, attr3Value  : STRING;
                        attr4Value, attr5Value, attr6Value  : STRING;

The xpfMakeAttrsHashTable function establishes a hash table for instances of one specific entity type. Such a hash table is made with a certain number of keys (max is 10). The function has a variable length argument list. xpfGetAttrsHashedValues looks up in a hash table made by xpfMakeAttrsHashTable, supplying the same number of keys (attribute values) that the hash table was made for. The function has a variable length argument list.

Arguments

1	Type	Name	Comment
2	GENERIC	hashTableIndex	the hash table index (returned from the xpfMakeAttrsHashTable function.
3	GENERIC	index	Generally one set of keys can result in more that one hit. Let index start with 1 and increment until the function returns XPNULLID in order to handle all of the instances that constitute the match.
4	BOOLEAN	attr(n)Value	The key (attribute) values

Return Value

Type	Name	Comment
INTEGER	instanceId	The returned instance identifier (that corresponds to the index)

  LOCAL
      entityId : GENERIC;
      product_hash_index : INTEGER;
      index : INTEGER;
      s_product : GENERIC;
   END_LOCAL;

    entityId := xpfGetEntity(XPXSOURCEMODELID, 'PRODUCT');
    product_hash_index := xpfMakeAttrsHashTable(XPXSOURCEMODELID, entityId, FALSE, 'PRODUCT_ID');

    index := 1;
    REPEAT WHILE(TRUE);
      s_product := xpfGetAttrsHashedValue(product_hash_index,index,'PROD-ID-1');
      IF(s_product :=: XPXNULLID) THEN
        ESCAPE;
      END_IF;
     (*
        .... handle the found instance here
     *)
      index += 1;
