Method Details

getFkMapping

public Map<String,CqnValue> getFkMapping()

getFkValues

public Map<String,Object> getFkValues(Map<String,Object> sourceObject)

getParentPkValues

public Map<String,Object> getParentPkValues()

getTargetPredicate

public CqnPredicate getTargetPredicate(CqnPredicate predicate)

Calculate the target predicate based on the on-condition and predicates' concrete values. Example: on-condition has (PK) id = (FK) parent_id, filter contains where id = 42. The resulting predicate will be where parent_id = 42

Parameters:

predicate - containing concrete values

Returns:

calculated target predicate
