Class `dmd.mtype.TypeInstance`

Similar to TypeIdentifier, but with a TemplateInstance as the root



class TypeInstance

  : TypeQualified
;

Methods

Name	Description
`accept`	Visits this AST node using the given visitor.
`addMod`	Add MODxxxx bits to existing type. We're adding, not replacing, so adding const to a shared type => "shared const"
`addSTC`	Apply STCxxxx bits to existing type. Use before semantic analysis is run.
`addStorageClass`	Add storage class modifiers to type.
`alignment`	Return alignment to use for this type.
`baseElemOf`	If this is a type of static array, return its base element type.
`castMod`	Apply MODxxxx bits to existing type.
`check`	Look for bugs in constructing types.
`checkComplexTransition`
`checkDeprecated`	Check type to see if it is based on a deprecated symbol.
`constConv`	Determine if converting 'this' to 'to' is an identity operation, a conversion to const operation, or the types aren't the same.
`constOf`	Convert to 'const'.
`covariant`	Covariant means that 'this' can substitute for 't', i.e. a pure function is a match for an impure type.
`deduceWild`	Compute MOD bits matching `this` argument type to wild parameter type.
`defaultInitLiteral`	Use when we prefer the default initializer to be a literal, rather than a global immutable variable.
`deinitialize`	Deinitializes the global state of the compiler.
`factory`	Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor.
`fixTo`	For our new type 'this', which is type-constructed from t, fill in the cto, ito, sto, scto, wto shortcuts.
`hasPointers`	Return !=0 if type has pointers that need to be scanned by the GC during a collection cycle.
`hasVoidInitPointers`	Detect if type has pointer fields that are initialized to void. Local stack variables with such void fields can remain uninitialized, leading to pointer bugs.
`hasWild`	Return !=0 if the type or any of its subtypes is wild.
`immutableOf`	Convert to 'immutable'.
`implicitConvTo`	Determine if 'this' can be implicitly converted to type 'to'.
`isAssignable`	When T is mutable,
`isBoolean`	Returns true if T can be converted to boolean value.
`merge2`	This version does a merge even if the deco is already computed. Necessary for types that have a deco, but are not merged.
`modToBuffer`	Store this type's modifier name into buf.
`modToChars`	Return this type's modifier name.
`mutableOf`	Make type mutable.
`needsDestruction`	true if when type goes out of scope, it needs a destructor applied. Only applies to value types, not ref types.
`needsNested`
`nextOf`	If this is a type of something, return that something.
`nullAttributes`	Return a copy of this type with all attributes null-initialized. Useful for creating a type with different modifiers.
`numberOfElems`	Compute number of elements for a (possibly multidimensional) static array, or 1 for other types.
`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.
`sizemask`	Return the mask that an integral type will fit into.
`toBasetype`	If this is a shell around another type, get that other type.
`toChars`	For pretty-printing a type.
`toHash`	Compute hash function for Object.
`toHeadMutable`	Return type with the top level of it being mutable.
`toPrettyChars`	For pretty-printing a type.
`toString`
`toString`	Convert Object to a human readable string.
`unSharedOf`	Make type unshared. 0 => 0 const => const immutable => immutable shared => 0 shared const => const wild => wild wild const => wild const shared wild => wild shared wild const => wild const
`wildOf`	Convert to 'wild'.
