dmd.declaration

Miscellaneous declarations, including typedef, alias, variable declarations including the implicit this declaration, type tuples, ClassInfo, ModuleInfo and various TypeInfos.
Authors:
bool checkFrameAccess(Loc loc, Scope* sc, AggregateDeclaration ad, size_t iStart = 0);
Check to see the aggregate type is nested and its context pointer is accessible from the current scope. Returns true if error occurs.
bool modifyFieldVar(Loc loc, Scope* sc, VarDeclaration var, Expression e1);
Mark variable v as modified if it is inside a constructor that var is a field in. Also used to allow immutable globals to be initialized inside a static constructor.
Returns:
true if it's an initialization of v
void ObjectNotFound(Identifier id);
abstract class Declaration: dmd.dsymbol.Dsymbol;
final bool checkDisabled(Loc loc, Scope* sc, bool isAliasedDeclaration = false);
Issue an error if an attempt to call a disabled method is made
If the declaration is disabled but inside a disabled function, returns true but do not issue an error message.
Parameters:
Loc loc Location information of the call
Scope* sc Scope in which the call occurs
bool isAliasedDeclaration if true searches overload set
Returns:
true if this Declaration is @disabled, false otherwise.
final Modifiable checkModify(Loc loc, Scope* sc, Expression e1, ModifyFlags flag);
Check to see if declaration can be modified in this context (sc). Issue error if not.
Parameters:
Loc loc location for error messages
Expression e1 null or this expression when this declaration is a field
Scope* sc context
ModifyFlags flag if the first bit is set it means do not issue error message for invalid modification; if the second bit is set, it means that this declaration is a field and a subfield of it is modified.
Returns:
Modifiable.yes or Modifiable.initialization
final const LINK resolvedLinkage();
Returns the linkage, resolving the target-specific System one.
final const pure nothrow @nogc @safe bool isReference();
Returns:
Whether the variable is a reference, annotated with out or ref
class TupleDeclaration: dmd.declaration.Declaration;
void foreachVar(scope void delegate(Dsymbol) dg);
Calls dg(Dsymbol) for each Dsymbol, which should be a VarDeclaration inside VarExp (isexp == true).
Parameters:
void delegate(Dsymbol) dg delegate to call for each Dsymbol
int foreachVar(scope int delegate(Dsymbol) dg);
Calls dg(Dsymbol) for each Dsymbol, which should be a VarDeclaration inside VarExp (isexp == true). If dg returns !=0, stops and returns that value else returns 0.
Parameters:
int delegate(Dsymbol) dg delegate to call for each Dsymbol
Returns:
last value returned by dg()
class AliasDeclaration: dmd.declaration.Declaration;
const bool isAliasedTemplateParameter();
Returns:
true if this instance was created to make a template parameter visible in the scope of a template body, false otherwise
class OverDeclaration: dmd.declaration.Declaration;
class VarDeclaration: dmd.declaration.Declaration;
final bool isDataseg();
Does symbol go into data segment? Includes extern variables.
final bool isThreadlocal();
Does symbol go into thread local storage?
final bool isCTFE();
Can variable be read and written by CTFE?
final bool canTakeAddressOf();
Return true if we can take the address of this variable.
final bool needsScopeDtor();
Return true if variable needs to call the destructor.
final Expression callScopeDtor(Scope* sc);
If a variable has a scope destructor call, return call for it. Otherwise, return NULL.
final Expression getConstInitializer(bool needFullType = true);
If variable has a constant expression initializer, get it. Otherwise, return null.
final Expression expandInitializer(Loc loc);
Helper function for the expansion of manifest constant.
final bool checkNestedReference(Scope* sc, Loc loc);
Check to see if this variable is actually in an enclosing function rather than the current one. Update nestedrefs[], closureVars[] and outerVars[].
Returns:
true if error occurs.
class BitFieldDeclaration: dmd.declaration.VarDeclaration;
C11 6.7.2.1-4 bit fields
final ulong getMinMax(Identifier id);
Retrieve the .min or .max values. Only valid after semantic analysis.
Parameters:
Identifier id Id.min or Id.max
Returns:
the min or max value
class SymbolDeclaration: dmd.declaration.Declaration;
This is a shell around a back end symbol
