Method Summary

protected void	checkFinalFieldAssignment(polyglot.ast.Stmt s, java.util.Set uninitFinalVars, JifContext A) Check if the stmt is an assignment to a final field.
protected polyglot.ast.Block	checkInitsAndBody(Label Li, JifConstructorInstance ci, polyglot.ast.Block body, LabelChecker lc) This method implements the check-inits predicate of the thesis (Figures 4.41-45).

labelCheck

public polyglot.ast.Node labelCheck(LabelChecker lc)
                             throws polyglot.types.SemanticException

Description copied from interface: Jif

Label check the node to which this extension is attached.

Specified by:

labelCheck in interface Jif

Overrides:

labelCheck in class Jif_c

Throws:

polyglot.types.SemanticException

uninitFinalFields

protected static java.util.Set uninitFinalFields(polyglot.types.ReferenceType type)

Utility method to get the set of field instances of final fields of the given ReferenceType that do not have an initializer.

checkInitsAndBody

protected polyglot.ast.Block checkInitsAndBody(Label Li,
                                               JifConstructorInstance ci,
                                               polyglot.ast.Block body,
                                               LabelChecker lc)
                                        throws polyglot.types.SemanticException

This method implements the check-inits predicate of the thesis (Figures 4.41-45).

Throws:

polyglot.types.SemanticException

checkFinalFieldAssignment

protected void checkFinalFieldAssignment(polyglot.ast.Stmt s,
                                         java.util.Set uninitFinalVars,
                                         JifContext A)
                                  throws polyglot.types.SemanticException

Check if the stmt is an assignment to a final field. Moreover, if the final field is a label, and it is being initialized from a final label, share the uids of the fields.

Throws:

polyglot.types.SemanticException
