MockArgs

enum class clang::ast_matchers::MockArgs

strong

This enum indicates whether the mock method in the matched ON_CALL or EXPECT_CALL macro has arguments.

For example, None can be used to match ON_CALL(mock, TwoParamMethod) whereas Some can be used to match ON_CALL(mock, TwoParamMethod(m1, m2)).

alignOfExpr()

internal::BindableMatcher< Stmt > clang::ast_matchers::alignOfExpr ( const internal::Matcher< UnaryExprOrTypeTraitExpr > &  InnerMatcher )

inline

Same as unaryExprOrTypeTraitExpr, but only matching alignof.

Definition at line 3036 of file ASTMatchers.h.

References allOf, anyOf, stmt, and unaryExprOrTypeTraitExpr.

anything()

internal::TrueMatcher clang::ast_matchers::anything ( )

inline

Matches any node.

Useful when another matcher requires a child matcher, but there's no additional constraint. This will often be used with an explicit conversion to an internal::Matcher<> type such as TypeMatcher.

Example: DeclarationMatcher(anything()) matches all declarations, e.g.,

"int* p" and "void f()" in
  int* p;
  void f();

Usable as: Any Matcher

clang::ast_matchers::AST_MATCHER_P	(	Expr	,

		InnerMatcher
	)

Matches expressions that match InnerMatcher that are possibly wrapped in an elidable constructor and other corresponding bookkeeping nodes.

In C++17, elidable copy constructors are no longer being generated in the AST as it is not permitted by the standard. They are, however, part of the AST in C++14 and earlier. So, a matcher must abstract over these differences to work in all language modes. This matcher skips elidable constructor-call AST nodes, ExprWithCleanups nodes wrapping elidable constructor-calls and various implicit nodes inside the constructor calls, all of which will not appear in the C++17 AST.

Given

struct H {};
H G();
void f() {
  H D = G();
}

varDecl(hasInitializer(ignoringElidableConstructorCall(callExpr()))) matches H D = G() in C++11 through C++17 (and beyond).

cxxRecordDecl( has(fieldDecl(hasName("a"), hasType(type().bind("t")))), has(fieldDecl(hasName("b"), hasType(type(equalsBoundNode("t")))))) matches the class X, as a and b have the same type.

Note that when multiple matches are involved via forEach* matchers, equalsBoundNodes acts as a filter. For example: compoundStmt( forEachDescendant(varDecl().bind("d")), forEachDescendant(declRefExpr(to(decl(equalsBoundNode("d")))))) will trigger a match for each combination of variable declaration and reference to that variable declaration within a compound statement.
