Class `dmd.dtemplate.TemplateDeclaration`

[mixin] template Identifier (parameters) [Constraint]


						
				class TemplateDeclaration
				
  : ScopeDsymbol
				;

Fields

Name	Type	Description
`deprecated_`	`bool`	this template declaration is deprecated
`inuse`	`int`	for recursive expansion detection
`isTrivialAlias`	`bool`	matches pattern `template Alias(T) { alias Alias = qualifiers(T); }`
`isTrivialAliasSeq`	`bool`	matches pattern `template AliasSeq(T...) { alias AliasSeq = T; }`
`cppnamespace`	`CPPNamespaceDeclaration`	C++ namespace this symbol belongs to

Methods

Name	Description
`addInstance` (ti)	Add instance ti to TemplateDeclaration's table of instances. Return a handle we can use to later remove it if it fails instantiation.
`declareParameter` (sc, tp, o)	Declare template parameter tp with value o, and install it in the scope sc.
`deduceFunctionTemplateMatch` (ti, sc, fd, tthis, fargs)	Match function arguments against a specific template function.
`doHeaderInstantiation` (ti, sc2, fd, tthis, fargs)	Limited function template instantiation for using fd.leastAsSpecialized()
`evaluateConstraint` (ti, sc, paramscope, dedargs, fd)	Check to see if constraint is satisfied.
`findExistingInstance` (tithis, fargs)	Given a new instance tithis of this TemplateDeclaration, see if there already exists an instance. If so, return that existing instance.
`getConstraintEvalError` (tip)	Destructively get the error message from the last constraint evaluation
`isOverloadable` ()	We can overload templates.
`isVariadic` ()	Check if the last template parameter is a tuple one, and returns it if so, else returns `null`.
`leastAsSpecialized` (sc, td2, fargs)	Determine partial specialization order of 'this' vs td2.
`matchWithInstance` (sc, ti, dedtypes, fargs, flag)	Given that ti is an instance of this TemplateDeclaration, deduce the types of the parameters to this, and store those deduced types in dedtypes[].
`overloadInsert` (s)	Overload existing TemplateDeclaration 'this' with the new one 's'. Return true if successful; i.e. no conflict.
`removeInstance` (ti)	Remove TemplateInstance from table of instances.
`scopeForTemplateParameters` (ti, sc)	Create a scope for the parameters of the TemplateInstance `ti` in the parent scope sc from the ScopeDsymbol paramsym.
`toCharsNoConstraints` ()	Similar to `toChars`, but does not print the template constraints
`_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.
`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.
`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.
`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 for `opEquals` should attempt to compare objects by their contents.
`pastMixin` ()	`pastMixin` returns the enclosing symbol if this is a template mixin.
`prot` ()
`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)
`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.
