getRequiredDeclarations
public Declaration[] getRequiredDeclarations()
- Description copied from interface:
Constraint
- Returns all the declarations required by the given
constraint implementation.
- Specified by:
getRequiredDeclarations
in interface Constraint
- Returns:
replaceDeclaration
public void replaceDeclaration(Declaration oldDecl,
Declaration newDecl)
- Description copied from interface:
Constraint
- When a rule contains multiple logical branches, i.e., makes
use of 'OR' CE, it is required to clone patterns and declarations
for each logical branch. Since this is done at ReteOO build
type, when constraints were already created, eventually
some constraints need to update their references to the
declarations.
