llvm::SmallPtrSet< const DeclRefExpr *, 16 > clang::tidy::utils::decl_ref_expr::constReferenceDeclRefExprs ( const VarDecl &  VarDecl,
const Stmt &  Stmt,
ASTContext &  Context 
)

◆ isCopyAssignmentArgument()

bool clang::tidy::utils::decl_ref_expr::isCopyAssignmentArgument ( const DeclRefExpr &  DeclRef,
const Decl Decl,
ASTContext &  Context 
)

Returns true if DeclRefExpr is the argument of a copy-assignment operator CallExpr within Decl.

Definition at line 135 of file DeclRefExprUtils.cpp.

◆ isCopyConstructorArgument()

bool clang::tidy::utils::decl_ref_expr::isCopyConstructorArgument ( const DeclRefExpr &  DeclRef,
const Decl Decl,
ASTContext &  Context 
)

Returns true if DeclRefExpr is the argument of a copy-constructor call expression within Decl.

◆ isOnlyUsedAsConst()

bool clang::tidy::utils::decl_ref_expr::isOnlyUsedAsConst ( const VarDecl &  Var,
const Stmt &  Stmt,
ASTContext &  Context 
)

Returns true if all DeclRefExpr to the variable within Stmt do not modify it.

Returns true if only const methods or operators are called on the variable or the variable is a const reference or value argument to a callExpr().
