Class dmd.expression.StructLiteralExp

sd( e1, e2, e3, ... )

class StructLiteralExp
  : Expression ;


elements dmd.root.array.Array!(dmd.expression.Expression)*parallels sd.fields[] with null entries for fields to skip
inlinecopy StructLiteralExpthose fields need to prevent a infinite recursion when one field of struct initialized with 'this' pointer.
isOriginal boolused when moving instances to indicate this is this.origin
origin StructLiteralExppointer to the origin instance of the expression. once a new expression is created, origin is set to 'this'. anytime when an expression copy is created, 'origin' pointer is set to 'origin' pointer value of the original expression.
sd StructDeclarationwhich aggregate this is for
stageflags intanytime when recursive function is calling, 'stageflags' marks with bit flag of current stage and unmarks before return from this function. 'inlinecopy' uses similar 'stageflags' and from multiple evaluation 'doInline' (with infinite recursion) of this expression.
stype Typefinal type of result (can be different from sd's type)
sym*back end symbol to initialize with literal
useStaticInit boolif this is true, use the StructDeclaration's init symbol


getField Gets expression at offset of type. Returns NULL if not found.
getFieldIndex Get index of field. Returns -1 if not found.
accept Visits this AST node using the given visitor.
addDtorHook Destructors are attached to VarDeclarations. Hence, if expression returns a temp that needs a destructor, make sure and create a VarDeclaration for that temp.
addressOf Take address of expression.
checkNogc Calling function f. Check the @nogc-ness, i.e. if we're in a @nogc function we can only call other @nogc functions. Returns true if error occurs.
checkPostblit Check that the postblit is callable if t is an array of structs. Returns true if error happens.
checkPurity Calling function f. Check the purity, i.e. if we're in a pure function we can only call other pure functions. Returns true if error occurs.
checkPurity Accessing variable v. Check for purity and safety violations. Returns true if error occurs.
checkReadModifyWrite 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.
checkSafety Calling function f. Check the safety, i.e. if we're in a @safe function we can only call @safe or @trusted functions. 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 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 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 Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor.
isBool Does this expression statically evaluate to a boolean 'result' (true or false)?
isLvalue Return !=0 if expression is an lvalue.
opCmp Compare with another Object obj.
opEquals Test whether this is equal to o. The default implementation only compares by identity (using the is operator). Generally, overrides for opEquals should attempt to compare objects by their contents.
resolveLoc Resolve _FILE__, _LINE__, _MODULE__, _FUNCTION__, _PRETTY_FUNCTION__, _FILE_FULL_PATH__ to loc.
toBoolean If expression can be tested for true or false, returns the modified expression. Otherwise returns ErrorExp.
toHash Compute hash function for Object.
toLvalue Give error if we're not an lvalue. If we can, convert expression to be an lvalue.
toString Convert Object to a human readable string.
