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
`fargs`	`dmd.root.array.Array!(dmd.expression.Expression)*`	For function template, these are the function fnames(name and loc of it) and arguments Relevant because different resolutions of `auto ref` parameters create different template instances even with the same template arguments
`inst`	`TemplateInstance`	If this is not null and it has a value that is not the current object, then this field points to an existing template instance and that object has been duplicated into us.
`memberOf`	`Module`	If this is not null then this template instance appears in a root module's members.
`importedScopes`	`dmd.root.array.Array!(dmd.dsymbol.Dsymbol)*`	symbols whose members have been imported, i.e. imported modules and template mixins
`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
`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.
`printInstantiationTrace` (cl, max_shown)	Given an error instantiating the TemplateInstance, give the nested TemplateInstance instantiations that got us here. Those are a list threaded into the nested scopes.
`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.
`getAccessModule` ()	Determine which Module a Dsymbol is in, as far as access rights go.
`getImportedScopes` ()
`getImportVisibilities` ()
`getModule` ()	Determine which Module a Dsymbol is in.
`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.
`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.
`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.
`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.
`toString` ()
`toString` ()	Convert Object to a human readable string.
`visible` ()
