Detailed Description

Representation of the declaration of a single variable.

In conjunction with an instance of the DeclSpecs, this gives us everything we need for a full variable declaration.

InitFromDeclSpecs()

void Declarator::InitFromDeclSpecs

DeclSpecs *

ds

)

Once a DeclSpecs instance is available, this method completes the initialization of the type member.

Member Data Documentation

arraySize

int Declarator::arraySize

For array declarators, this gives the declared size of the array. Unsized arrays have arraySize == 0.

Definition at line 158 of file decl.h.

Referenced by Declarator(), InitFromType(), and Print().

child

Declarator* Declarator::child

Child pointer if needed; this can only be non-NULL if the declarator's kind isn't DK_BASE.

Definition at line 149 of file decl.h.

Referenced by Declarator(), InitFromType(), and Print().

functionParams

std::vector<Declaration *> Declarator::functionParams

For function declarations, this holds the Declaration *s for the function's parameters.

Definition at line 172 of file decl.h.

Referenced by InitFromType(), and Print().

initExpr

Expr* Declarator::initExpr

Initialization expression for the variable. May be NULL.

Definition at line 164 of file decl.h.

Referenced by Declarator(), Declaration::GetVariableDeclarations(), and Print().

kind

const DeclaratorKind Declarator::kind

The kind of this declarator; complex declarations are assembled as a hierarchy of Declarators. (For example, a pointer to an int would have a root declarator with kind DK_POINTER and with the Declarator::child member pointing to a DK_BASE declarator for the int).

Definition at line 145 of file decl.h.

Referenced by InitFromType(), and Print().

name

std::string Declarator::name

Name associated with the declarator.

Definition at line 161 of file decl.h.

Referenced by Declaration::DeclareFunctions(), GetStructTypesNamesPositions(), Declaration::GetVariableDeclarations(), InitFromType(), and Print().

pos

const SourcePos Declarator::pos

Position of the declarator in the source program.

Definition at line 138 of file decl.h.

Referenced by Declaration::DeclareFunctions(), GetStructTypesNamesPositions(), Declaration::GetVariableDeclarations(), InitFromDeclSpecs(), InitFromType(), and Print().

storageClass

StorageClass Declarator::storageClass

Definition at line 154 of file decl.h.

Referenced by Declarator(), Declaration::DeclareFunctions(), Declaration::GetVariableDeclarations(), InitFromDeclSpecs(), and Print().

type

const Type* Declarator::type

Type of the declarator. This is NULL until InitFromDeclSpecs() or InitFromType() is called.

Definition at line 168 of file decl.h.

Referenced by Declarator(), Declaration::DeclareFunctions(), GetStructTypesNamesPositions(), Declaration::GetVariableDeclarations(), InitFromDeclSpecs(), and InitFromType().

typeQualifiers

int Declarator::typeQualifiers

Type qualifiers provided with the declarator.

Definition at line 152 of file decl.h.

Referenced by Declarator(), InitFromType(), and Print().
