- enum
ClassKind
: int; - The ClassKind enum is used in AggregateDeclaration AST nodes to specify the linkage type of the struct/class/interface or if it is an anonymous class. If the class is anonymous it is also considered to be a D class.
d
- the aggregate is a d(efault) class
cpp
- the aggregate is a C++ struct/class/interface
objc
- the aggregate is an Objective-C class/interface
- abstract class
AggregateDeclaration
: dmd.dsymbol.ScopeDsymbol; -
- ClassKind
classKind
; - specifies whether this is a D, C++, Objective-C or anonymous struct/class/interface
- Scope*
newScope
(Scope*sc
); - Create a new scope from sc. semantic, semantic2 and semantic3 will use this for aggregate members.
- final bool
determineFields
(); - Find all instance fields, then push them into fields.Runs semantic() for all instance field variables, but also the field types can remain yet not resolved forward references, except direct recursive definitions. After the process sizeok is set to Sizeok.fwd.Returns:false if any errors occur.
- final size_t
nonHiddenFields
(); - Returns:The total number of fields minus the number of hidden fields.
- final bool
determineSize
(Locloc
); - Collect all instance fields, then determine instance size.Returns:false if failed to determine the size.
- final bool
checkOverlappedFields
(); - Calculate field[i].overlapped and overlapUnsafe, and check that all of explicit field initializers have unique memory space on instance.Returns:true if any errors happen.
- final bool
fill
(Locloc
, Expressions*elements
, boolctorinit
); - Fill out remainder of elements[] with default initializers for fields[].Parameters:
Loc loc
location Expressions* elements
explicit arguments which given to construct object. bool ctorinit
true if the elements will be used for default initialization. Returns:false if any errors occur. Otherwise, returns true and the missing arguments will be pushed in elements[]. - static pure nothrow @safe void
alignmember
(structalign_talignment
, uintsize
, uint*poffset
); - Do byte or word alignment as necessary. Align sizes of 0, as we may not know array sizes yet.Parameters:
structalign_t alignment
struct alignment that is in effect uint size
alignment requirement of field uint* poffset
pointer to offset to be aligned - static uint
placeField
(uint*nextoffset
, uintmemsize
, uintmemalignsize
, structalign_talignment
, uint*paggsize
, uint*paggalignsize
, boolisunion
); - Place a member (mem) into an aggregate (agg), which can be a struct, union or classReturns:offset to place field at nextoffset: next location in aggregate memsize: size of member memalignsize: natural alignment of member alignment: alignment in effect for this member paggsize: size of aggregate (updated) paggalignsize: alignment of aggregate (updated) isunion: the aggregate is a union
- final const bool
isNested
(); - Returns true if there's an extra member which is the 'this' pointer to the enclosing context (enclosing aggregate or function)
- final Dsymbol
searchCtor
(); - Look for constructor declaration.
