Class dmd.expression.ClassReferenceExp

A reference to a class, or an interface. We need this when we point to a base class (we must record what the type is).

class ClassReferenceExp
  : Expression ;

Methods

NameDescription
accept (v) Visits this AST node using the given visitor.
addressOf () Take address of expression.
checkReadModifyWrite (rmwOp, ex) Check whether the expression allows RMW operations, error with rmw operator diagnostic if not. ex is the RHS expression, or NULL if ++/-- is used (for diagnostics) Returns true if error occurs.
checkType () Check that the expression has a valid type. If not, generates an error "... has no type".
checkValue () Check that the expression has a valid value. If not, generates an error "... has no value".
combine (e1, e2) Combine e1 and e2 by CommaExp if both are not NULL.
copy () Does *not* do a deep copy.
deinitialize () Deinitializes the global state of the compiler.
deref () If this is a reference, dereference it.
extractLast (e, e0) If 'e' is a tree of commas, returns the rightmost expression by stripping off it from the tree. The remained part of the tree is returned via e0. Otherwise 'e' is directly returned and e0 is set to NULL.
factory (classname) Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor.
isIdentical (e) Identical, not just equal. I.e. NaNs with different bit patterns are not identical
isLvalue () Return !=0 if expression is an lvalue.
opCmp (o) Compare with another Object obj.
opEquals (o) Test whether this is equal to o. The default implementation only compares by identity (using the is operator). Generally, overrides and overloads for opEquals should attempt to compare objects by their contents. A class will most likely want to add an overload that takes your specific type as the argument and does the content comparison. Then you can override this and forward it to your specific typed overload with a cast. Remember to check for null on the typed overload.
size ()
toBool () Statically evaluate this expression to a bool if possible
toHash () Compute hash function for Object.
toString ()
toString () Convert Object to a human readable string.
