Class `dmd.dtemplate.TemplateInstance`


						
				class TemplateInstance
				
  : ScopeDsymbol
				;

Constructors

Name	Description
`this` (loc, td, tiargs)	This constructor is only called when we figured out which function template to instantiate.

Fields

Name	Type	Description
`cppnamespace`	`CPPNamespaceDeclaration`	C++ namespace this symbol belongs to
`localNum`	`ushort`	perturb mangled name to avoid collisions with those in FuncDeclaration.localsymtab

Properties

Name	Type	Description
`gagged`[get]	`bool`	if the instantiation is done with error gagging
`havetempdecl`[get]	`bool`	if used second constructor
`semantictiargsdone`[get]	`bool`	has semanticTiargs() been done?

Methods

Name	Description
`appendToModuleMember` ()	Append 'this' to the specific module members[]
`declareParameters` (sc)	Declare parameters of template instance, initialize them with the template instance arguments.
`equalsx` (ti)	Compare proposed template instantiation with existing template instantiation. Note that this is not commutative because of the auto ref check.
`findBestMatch` (sc, fargs)	Find the TemplateDeclaration that matches this TemplateInstance best.
`findTempDecl` (sc, pwithsym)	Find template declaration corresponding to template instance.
`genIdent` (args)	This instance needs an identifier for name mangling purposes. Create one by taking the template declaration name and adding the type signature for it.
`getIdent` ()	Lazily generate identifier for template instance. This is because 75% of the ident's are never needed.
`hasNestedArgs` (args, isstatic)	Determines if a TemplateInstance will need a nested generation of the TemplateDeclaration. Sets enclosing property if so, and returns != 0;
`isDiscardable` ()
`needsCodegen` ()	Returns true if this is not instantiated in non-root module, and is a part of non-speculative instantiatiation.
`needsTypeInference` (sc, flag)	Determine if template instance is really a template function, and that template function needs to infer types from the function arguments.
`printInstantiationTrace` (cl)	Given an error instantiating the TemplateInstance, give the nested TemplateInstance instantiations that got us here. Those are a list threaded into the nested scopes.
`semanticTiargs` (loc, sc, tiargs, flags, atd)	Run semantic of tiargs as arguments of template.
`semanticTiargs` (sc)	Run semantic on the elements of tiargs.
`updateTempDecl` (sc, s)	Confirm s is a valid template, then store it.
`_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.
`arraySyntaxCopy` (a)	Do syntax copy of an array of Dsymbol's.
`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.
`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.
`findGetMembers` ()	Look for member of the form: const(MemberInfo)[] getMembers(string); Returns NULL if not found
`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.
`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.
`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.
`searchX` (loc, sc, id, flags)	Search for identifier id as a member of `this`. `id` may be a template instance.
`setScope` (sc)	Set scope for future semantic analysis so we can deal better with forward references.
`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` ()
