Member Function Documentation

◆ getNilReceiver()

const Expr * NilReceiverBRVisitor::getNilReceiver ( const Stmt S,
const ExplodedNode N 
)
static

If the statement is a message send expression with nil receiver, returns the receiver expression.

Returns NULL otherwise.

◆ Profile()

void clang::ento::NilReceiverBRVisitor::Profile ( llvm::FoldingSetNodeID &  ID) const

Implements clang::ento::BugReporterVisitor.

Definition at line 431 of file BugReporterVisitors.h.

References ID.

◆ VisitNode()

PathDiagnosticPieceRef NilReceiverBRVisitor::VisitNode ( const ExplodedNode Succ,
BugReporterContext BRC,
PathSensitiveBugReport BR 
)
overridevirtual

Return a diagnostic piece which should be associated with the given node.

Note that this function does not get run on the very last node of the report, as the PathDiagnosticPiece associated with the last node should be unique. Use getEndPath to customize the note associated with the report end instead.

The last parameter can be used to register a new visitor with the given BugReport while processing a node.

Implements clang::ento::BugReporterVisitor.
