labelCheckField in interface JifFieldDeclExt

Throws:

polyglot.types.SemanticException

labelCheck

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

Label check field initializers. the PC of field initializer is the bottom label, because the initializer is always executed after invoking super constructor and before invoking the constructor of this class. (like the single path rule)

Specified by:

labelCheck in interface Jif

labelCheck in class Jif_c

Throws:

polyglot.types.SemanticException
