dmd.declaration

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;

https://dlang.org/spec/declaration.html#AliasDeclaration

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
