Detailed Description

This represents one expression.

Note that Expr's are subclasses of Stmt. This allows an expression to be transparently used any place a Stmt is required.

◆ NullPointerConstantKind

enum clang::Expr::NullPointerConstantKind

Enumeration used to describe the kind of Null pointer constant returned from isNullPointerConstant().

Enumerator
NPCK_NotNull	Expression is not a Null pointer constant.
NPCK_ZeroExpression	Expression is a Null pointer constant built from a zero integer expression that is not a simple, possibly parenthesized, zero literal. C++ Core Issue 903 will classify these expressions as "not pointers" once it is adopted. http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_active.html#903
NPCK_ZeroLiteral	Expression is a Null pointer constant built from a literal zero.
NPCK_CXX11_nullptr	Expression is a C++11 nullptr.
NPCK_GNUNull	Expression is a GNU-style __null constant.

Definition at line 704 of file Expr.h.

◆ NullPointerConstantValueDependence

enum clang::Expr::NullPointerConstantValueDependence

Enumeration used to describe how isNullPointerConstant() should cope with value-dependent expressions.

Enumerator
NPC_NeverValueDependent	Specifies that the expression should never be value-dependent.
NPC_ValueDependentIsNull	Specifies that a value-dependent expression of integral or dependent type should be considered a null pointer constant.
NPC_ValueDependentIsNotNull	Specifies that a value-dependent expression should be considered to never be a null pointer constant.

Definition at line 727 of file Expr.h.

◆ SideEffectsKind

enum clang::Expr::SideEffectsKind

Enumerator
SE_NoSideEffects	Strictly evaluate the expression.
SE_AllowUndefinedBehavior	Allow UB that we can give a value, but not arbitrary unmodeled side effects.
SE_AllowSideEffects	Allow any unmodeled side effect.

Classification clang::Expr::Classify ( ASTContext & Ctx ) const

inline

Classify - Classify this expression according to the C++11 expression taxonomy.

C++11 defines ([basic.lval]) a new taxonomy of expressions to replace the old lvalue vs rvalue. This function determines the type of expression this is. There are three expression types:

lvalues are classical lvalues as in C++03.
prvalues are equivalent to rvalues in C++03.
xvalues are expressions yielding unnamed rvalue references, e.g. a function returning an rvalue reference. lvalues and xvalues are collectively referred to as glvalues, while prvalues and xvalues together form rvalues.

ClassifyModifiable - Classify this expression according to the C++11 expression taxonomy, and see if it is valid on the left side of an assignment.

This function extends classify in that it also tests whether the expression is modifiable (C99 6.3.2.1p1).

Parameters

Loc	A source location that might be filled with a relevant location if the expression is not modifiable.

Whether this expression is instantiation-dependent, meaning that it depends in some way on a template parameter, even if neither its type nor (constant) value can change due to the template instantiation.

In the following example, the expression sizeof(sizeof(T() + T())) is instantiation-dependent (since it involves a template parameter T), but is neither type- nor value-dependent, since the type of the inner sizeof is known (std::size_t) and therefore the size of the outer sizeof is known.

◆ isLValue()

bool clang::Expr::isLValue ( ) const

isLValue - True if this expression is an "l-value" according to the rules of the current language.

C and C++ give somewhat different rules for this concept, but in general, the result of an l-value expression identifies a specific object whereas the result of an r-value expression is a value detached from any specific storage.

C++11 divides the concept of "r-value" into pure r-values ("pr-values") and so-called expiring values ("x-values"), which identify specific objects that can be safely cannibalized for their resources. This is an unfortunate abuse of terminology on the part of the C++ committee. In Clang, when we say "r-value", we generally mean a pr-value.
