Method Summary

Modifier and Type	Method and Description
protected void	checkFinalFieldAssignment(polyglot.ast.Stmt s_, java.util.Set<JifFieldInstance> 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).
polyglot.ast.Node	labelCheck(LabelChecker lc) Label check the node to which this extension is attached.
protected void	setEndOfInitChecking(LabelChecker lc, JifConstructorInstance ci)
protected static java.util.Set<JifFieldInstance>	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.
protected void	updateContextForNextStmt(LabelChecker lc, JifContext A, PathMap Xprev) Utility method for updating the context for checking the next statement in the block.

Method Detail

labelCheck

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

Description copied from interface: JifExt

Label check the node to which this extension is attached.

Specified by:

labelCheck in interface JifExt

Overrides:

labelCheck in class JifExt_c

Throws:

polyglot.types.SemanticException

uninitFinalFields

protected static java.util.Set<JifFieldInstance> 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

updateContextForNextStmt

protected void updateContextForNextStmt(LabelChecker lc,
                                        JifContext A,
                                        PathMap Xprev)

Utility method for updating the context for checking the next statement in the block. Useful for overriding in projects like fabric.

setEndOfInitChecking

protected void setEndOfInitChecking(LabelChecker lc,
                                    JifConstructorInstance ci)

checkFinalFieldAssignment

protected void checkFinalFieldAssignment(polyglot.ast.Stmt s_,
                                         java.util.Set<JifFieldInstance> 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
