isLevelExist

public boolean isLevelExist(IfaceTbKey tbkey,
                            java.util.List exclusiveCols,
                            boolean isLeaf)
                     throws MXException

Checks if a level exists or not. First checks if any of the exclusive keys are not null. If all are null then goes on to check if any of the exclusive columns are not null. If both the checks return negative it returns false indicating the level does not exist. This was done to handle interfaces like Inventory where a child level [INVCOST] migh have all exclusive keys null. Validates if any one of the exclusive keys are reqd and their value is null.

Parameters:

tbkey -

exclusiveCols -

isLeaf -

Returns:

true if the object [level] exists in the flat data

Throws:

java.sql.SQLException

MXException

getKeyValues

public java.lang.String getKeyValues(java.lang.String tableName,
                                     IfaceTbKey tbkey)
                              throws MXException

The key value for that table. This includes the keys of the parents [if any] also. This is used to hold reference to the created Elements for that level in the internal datastructure maintained by ConvertToStructure.

Parameters:

Returns:

the key values as a cacncatenated string

Throws:
