◆ digThroughConstructorsConversions()

const Expr * clang::tidy::modernize::digThroughConstructorsConversions ( const Expr *  E)

Look through conversion/copy constructors and member functions to find the explicit initialization expression, returning it is found.

The main idea is that given vector<int> v; we consider either of these initializations vector<int>::iterator it = v.begin(); vector<int>::iterator it(v.begin()); vector<int>::const_iterator it(v.begin()); and retrieve v.begin() as the expression used to initialize it but do not include vector<int>::iterator it; vector<int>::iterator it(v.begin(), 0); // if this constructor existed as being initialized from v.begin()

Returns true when the index expression is a declaration reference to IndexVar, Obj is the same expression as SourceExpr after all parens and implicit casts are stripped off.

This function is intended for array-like containers, as it makes sure that both the container and the index match. If the loop has index variable index and iterates over container, then isIndexInSubscriptExpr returns true for

for (containerType::iterator it = container.begin(),
e = createIterator(); it != e; ++it) { ... }
for (containerType::iterator it = container.begin();
it != anotherContainer.end(); ++it) { ... }
for (containerType::iterator it = begin(container),
e = end(container); it != e; ++it) { ... }
for (containerType::iterator it = std::begin(container),
e = std::end(container); it != e; ++it) { ... }

The following string identifiers are bound to the parts of the AST: InitVarName: 'it' (as a VarDecl) LoopName: The entire for loop (as a ForStmt) In the first example only: EndVarName: 'e' (as a VarDecl) In the second example only: EndCallName: 'container.end()' (as a CXXMemberCallExpr) In the third/fourth examples: 'end(container)' or 'std::end(container)' (as a CallExpr)

Client code will need to make sure that:

  • The two containers on which 'begin' and 'end' are called are the same.

◆ makePseudoArrayLoopMatcher()

StatementMatcher clang::tidy::modernize::makePseudoArrayLoopMatcher ( )

The matcher used for array-like containers (pseudoarrays).

This matcher is more flexible than array-based loops. It will match loops of the following textual forms (regardless of whether the iterator type is actually a pointer type or a class type):

for (int i = 0, j = container.size(); i < j; ++i) { ... }
for (int i = 0; i < container.size(); ++i) { ... }
for (int i = 0; i < size(container); ++i) { ... }

The following string identifiers are bound to the parts of the AST: InitVarName: 'i' (as a VarDecl) LoopName: The entire for loop (as a ForStmt) In the first example only: EndVarName: 'j' (as a VarDecl) In the second example only: EndCallName: 'container.size()' (as a CXXMemberCallExpr) or 'size(contaner)' (as a CallExpr)

Client code will need to make sure that:

  • The containers on which 'size()' is called is the container indexed.
  • The index variable is only used in overloaded operator[] or container.at().
  • The container's iterators would not be invalidated during the loop.
