`ctor`	`Dsymbol`	CtorDeclaration or TemplateDeclaration

`dtor`	`DtorDeclaration`	the aggregate destructor exposed as `__xdtor` alias
`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.

`getRTInfo`	`Expression`	pointer to GC info generated by object.RTInfo(this)
`importedScopes`	`dmd.root.array.Array!(dmd.dsymbol.Dsymbol)*`	symbols whose members have been imported, i.e. imported modules and template mixins
`inv`	`FuncDeclaration`	Merged invariant calling all members of invs
`invs`	`dmd.root.array.Array!(dmd.func.FuncDeclaration)`	Array of invariants
`localNum`	`ushort`	perturb mangled name to avoid collisions with those in FuncDeclaration.localsymtab

`sinit`	`void*`	initializer symbol
`sizeok`	`dmd.astenums.Sizeok`	set when structsize contains valid data
`storage_class`	`ulong`
`structsize`	`uint`	size of struct
`tidtor`	`DtorDeclaration`	(same as aggrDtor, except for C++ classes with virtual dtor on Windows)
`type`	`Type`
`userDtors`	`dmd.root.array.Array!(dmd.func.DtorDeclaration)`	user-defined destructors (`~this()`) - mixins can yield multiple ones
`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

Methods

Name	Description
`addObjcSymbols` (classes, categories)
`findFunc` (ident, tf)	Find virtual function matching identifier and type. Used to build virtual function tables for interface implementations.
`hasMonitor` ()
`isAbstract` ()
`isBaseInfoComplete` ()	Determine if 'this' has complete base class information. This is used to detect forward references in covariant overloads.
`isBaseOf` (cd, poffset)	Determine if 'this' is a base class of cd.
`isBaseOf2` (cd)	Determine if 'this' is a base class of cd. This is used to detect circular inheritance only.
`isCOMclass` ()
`kind` ()
`searchBase` (ident)	Search base classes in depth-first, left-to-right order for a class or interface named 'ident'. Stops at first found. Does not look for additional matches.
`vtblOffset` ()	Determine if slot 0 of the vtbl[] is reserved for something else. For class objects, yes, this is where the classinfo ptr goes. For COM interfaces, no. For non-COM interfaces, yes, this is where the Interface ptr goes.
`accept` (v)
`addComment` (comment)	Add documentation comment to Dsymbol. Ignore NULL comments.
`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.
`comment` ()	get documentation comment for this Dsymbol
`ddocUnittest` ()	Get ddoc unittest associated with this symbol. (only use this with ddoc)
`ddocUnittest` (utd)	Set ddoc unittest associated with this symbol.
`deinitialize` ()	Deinitializes the global state of the compiler.
`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[].
`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.
`getImportedScopes` ()
`getImportVisibilities` ()
`getModule` ()	Determine which Module a Dsymbol is in.
`hasPointers` ()	Is Dsymbol a variable that contains pointers?
`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.
`isCsymbol` ()	Does this Dsymbol come from a C file?
`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)
`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 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.
`pastMixin` ()	`pastMixin` returns the enclosing symbol if this is a template mixin.
`searchCtor` ()	Look for constructor declaration.
`setDeprecated` ()	Flag this aggregate as deprecated
`size` (loc)
`symtabInsert` (s)	Insert Dsymbol in table.
`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` ()
