Class `dmd.dtemplate.TemplateDeclaration`

[mixin] template Identifier (parameters) [Constraint]


						
				class TemplateDeclaration
				
  : ScopeDsymbol
				;

Fields

Name	Type	Description
`inuse`	`int`	for recursive expansion detection
`cppnamespace`	`CPPNamespaceDeclaration`	C++ namespace this symbol belongs to

Methods

Name	Description
`addInstance`	Add instance ti to TemplateDeclaration's table of instances. Return a handle we can use to later remove it if it fails instantiation.
`declareParameter`	Declare template parameter tp with value o, and install it in the scope sc.
`deduceFunctionTemplateMatch`	Match function arguments against a specific template function.
`doHeaderInstantiation`	Limited function template instantiation for using fd.leastAsSpecialized()
`evaluateConstraint`	Check to see if constraint is satisfied.
`findExistingInstance`	Given a new instance tithis of this TemplateDeclaration, see if there already exists an instance. If so, return that existing instance.
`getConstraintEvalError`	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`	Determine partial specialization order of 'this' vs td2.
`matchWithInstance`	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`	Overload existing TemplateDeclaration 'this' with the new one 's'. Return true if successful; i.e. no conflict.
`removeInstance`	Remove TemplateInstance from table of instances.
`scopeForTemplateParameters`	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`	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`
`addComment`	Add documentation comment to Dsymbol. Ignore NULL comments.
`apply`	Iterate this dsymbol or members of this scoped dsymbol, then call `fp` with the found symbol and `param`.
`arraySyntaxCopy`	Do syntax copy of an array of Dsymbol's.
`factory`	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`	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`	Determine if this symbol is only one.
`oneMembers`	Same as Dsymbol::oneMember(), but look at an array of Dsymbols.
`opCmp`	Compare with another Object obj.
`opEquals`	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`	This function is #1 on the list of functions that eat cpu time. Be very, very careful about slowing it down.
`searchX`	Search for identifier id as a member of `this`. `id` may be a template instance.
`setScope`	Set scope for future semantic analysis so we can deal better with forward references.
`size`
`symtabLookup`	Look up identifier in symbol table.
`syntaxCopy`	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`	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.
