Class dmd.dstruct.UnionDeclaration

Unions are a variation on structs.

class UnionDeclaration
  : StructDeclaration ;


aggNew NewDeclarationallocator
aliasthis AliasThisforward unresolved lookups to aliasthis
alignsize uintsize of struct for alignment purposes
classKind ClassKindspecifies whether this is a D, C++, Objective-C or anonymous struct/class/interface
cppmangle dmd.globals.CPPMANGLESpecify whether to mangle the aggregate as a class or a struct This information is used by the MSVC mangler Only valid for class and struct. TODO: Merge with ClassKind ?
cppnamespace CPPNamespaceDeclarationC++ namespace this symbol belongs to
ctor DsymbolCtorDeclaration or TemplateDeclaration
defaultCtor CtorDeclarationdefault constructor - should have no arguments, because it would be stored in TypeInfo_Class.defaultConstructor
deferred Dsymbolany deferred semantic2() or semantic3() symbol
dtor DtorDeclarationaggregate destructor calling dtors and member constructors
dtors dmd.root.array.Array!(dmd.func.DtorDeclaration)Array of destructors
enclosing Dsymbol!=null if is nested pointing to the dsymbol that directly enclosing it. 1. The function that enclosing it (nested struct and class) 2. The class that enclosing it (nested class only) 3. If enclosing aggregate is template, its enclosing dsymbol.
fieldDtor FuncDeclarationaggregate destructor for just the fields
fields dmd.root.array.Array!(dmd.declaration.VarDeclaration)VarDeclaration fields
getRTInfo Expressionpointer to GC info generated by object.RTInfo(this)
inv FuncDeclarationMerged invariant calling all members of invs
invs dmd.root.array.Array!(dmd.func.FuncDeclaration)Array of invariants
localNum ushortperturb mangled name to avoid collisions with those in FuncDeclaration.localsymtab

noDefaultCtor boolno default construction
primaryDtor DtorDeclarationnon-deleting C++ destructor, same as dtor for D

stag*tag symbol for debug data
storage_class ulong

tidtor DtorDeclarationaggregate destructor used in TypeInfo (must have extern(D) ABI)
type Type
visibility dmd.dsymbol.Visibility
vthis VarDeclaration'this' parameter if this aggregate is nested
vthis2 VarDeclaration'this' parameter if this aggregate is a template and is nested


_foreach (sc, members, dg, pn) Expands attribute declarations in members in depth first order. Calls dg(size_t symidx, Dsymbol *sym) for each member. If dg returns !=0, stops and returns that value else returns 0. Use this function to avoid the O(N + N^2/2) complexity of calculating dim and calling N times getNth.
accept (v)
addComment (comment) Add documentation comment to Dsymbol. Ignore NULL comments.
alignmember (alignment, size, poffset) Do byte or word alignment as necessary. Align sizes of 0, as we may not know array sizes yet.
arraySyntaxCopy (a) Do syntax copy of an array of Dsymbol's.
checkOverlappedFields () Calculate field[i].overlapped and overlapUnsafe, and check that all of explicit field initializers have unique memory space on instance.
determineFields () Find all instance fields, then push them into fields.
determineSize (loc) Collect all instance fields, then determine instance size.
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.
fill (loc, elements, ctorinit) Fill out remainder of elements[] with default initializers for fields[].
findGetMembers () Look for member of the form: const(MemberInfo)[] getMembers(string); Returns NULL if not found
fit (loc, sc, elements, stype) Fit elements[] to the corresponding types of the struct's fields.
followInstantiationContext (p1, p2) Returns true if any of the symbols p1 or p2 resides in the enclosing instantiation scope of this.
getAccessModule () Determine which Module a Dsymbol is in, as far as access rights go.
getModule () Determine which Module a Dsymbol is in.
hasPointers () Is Dsymbol a variable that contains pointers?
hasRegularCtor (checkDisabled) Verifies whether the struct declaration has a constructor that is not a copy constructor. Optionally, it can check whether the struct declaration has a regular constructor, that is not disabled.
hasStaticCtorOrDtor () Return true if any of the members are static ctors or static dtors, or if any members have members that are.
inNonRoot () Returns true if this symbol is defined in a non-root module without instantiation.
isMember () Returns an AggregateDeclaration when toParent() is that.
isMember2 () Returns an AggregateDeclaration when toParent2() is that.
isMemberDecl () Returns an AggregateDeclaration when toParentDecl() is that.
isMemberLocal () Returns an AggregateDeclaration when toParentLocal() is that.
isNested () Returns true if there's an extra member which is the 'this' pointer to the enclosing context (enclosing aggregate or function)
isPOD () Determine if struct is POD (Plain Old Data).
newScope (sc) Create a new scope from sc. semantic, semantic2 and semantic3 will use this for aggregate members.
nonHiddenFields ()
oneMember (ps, ident) Determine if this symbol is only one.
oneMembers (members, ps, ident) Same as Dsymbol::oneMember(), but look at an array of Dsymbols.
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 for opEquals should attempt to compare objects by their contents.
pastMixin () pastMixin returns the enclosing symbol if this is a template mixin.
placeField (nextoffset, memsize, memalignsize, alignment, paggsize, paggalignsize, isunion) Place a member (mem) into an aggregate (agg), which can be a struct, union or class
search (loc, ident, flags) This function is #1 on the list of functions that eat cpu time. Be very, very careful about slowing it down.
searchCtor () Look for constructor declaration.
searchX (loc, sc, id, flags) Search for identifier id as a member of this. id may be a template instance.
setDeprecated () Flag this aggregate as deprecated
setScope (sc) Set scope for future semantic analysis so we can deal better with forward references.
size (loc)
symtabLookup (s, id) Look up identifier in symbol table.
syntaxCopy (s) Copy the syntax. Used for template instantiations. If s is NULL, allocate the new object, otherwise fill it in.
toAlias () If this symbol is really an alias for another, return that other. If needed, semantic() is invoked due to resolve forward reference.
toAlias2 () Resolve recursive tuple expansion in eponymous template.
toHash () Compute hash function for Object.
toParent () parent field returns a lexically enclosing scope symbol this is a member of.
toParent2 () parent field returns a lexically enclosing scope symbol this is a member of.
toParentDecl () parent field returns a lexically enclosing scope symbol this is a member of.
toParentLocal () parent field returns a lexically enclosing scope symbol this is a member of.
toParentP (p1, p2) Returns the declaration scope scope of this unless any of the symbols p1 or p2 resides in its enclosing instantiation scope then the latter is returned.
toString ()
toString () Convert Object to a human readable string.
visible ()
