dmd.declaration

Compiler implementation of the D programming language.
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.
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, int 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
int flag !=0 means do not issue error message for invalid modification
Returns:
Modifiable.yes or Modifiable.initialization

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. Returns true if error occurs.
final const pure bool enclosesLifetimeOf(VarDeclaration v);
Determine if this has a lifetime that lasts past the destruction of v
Parameters:
VarDeclaration v variable to test against
Returns:
true if it does
final void addMaybe(VarDeclaration v);
Add variable to maybes[]. When a maybescope variable v is assigned to a maybescope variable this, we cannot determine if this is actually scope until the semantic analysis for the function is completed. Thus, we save the data until then.
Parameters:
VarDeclaration v an STC.maybescope variable that was assigned to this
