SgClassDeclaration Class Reference

Description

This class represents the concept of a class declaration statement. It includes the concept of an instantiated class template as well.

Declaration statements are where variables and types are defined and become available for use within a program. Declarations are strored in symbols (SgSymbol) and used to associate the symbol with a location within a scope within the application source code. There are many different types of declarations, within Sage III the SgDeclaration forms a base class for numerous IR nodes such as: class declarations (including structs and unions), enum declarations, function declarations, namespace declarations, pragma declarations, template declarations, typedef declarations, using declarations, using directives, variable declarations, etc.

An important concept for a few types fo declarations is that of defining vs. non-defining. Defining declarations are associated with definitions, for example a class definition or function definition. A class declaration where a class is defined (instead of a forward declaration) is a defining declaration. A forward declaration is a non-defining declaration. Some declarations are not explicitly forward declarations, they are non-defining declarations. Only declarations where there is a definition are defining declarations. Because definitions can at most appear once within a translation unit (a source file and it included header files), there is at most one defining declaration. The defining declaration is never shared, however the non-defining declaration can be shared and is required to be shared if there is more than one location in the AST where a non-defining declaration is required. There is at most one defining and one non-defining declaration (at some point they will also share their name, but this is not implemented yet). If a variable is defined to be extern or only defined through a refererence or pointer, then there would be no defining declaration (only a non-defining declaration).

The following code contains no defining declaration for the type "foobar":

typedef struct foobar *((FunctionPointer)(void);
foobar* foobar_pointer = NULL;

and yet is vailid code (even though there is no explicit forward declaration of "foobar" as a class (or struct). In this case foobar is represented using a non-defining declaration internally and that declaration is reference multiple types (once within each statement). Note that the code abouve is valid C++, and not valid C code (to make it valid C code we would have to add "struct" the pointer declaration, for example:

struct foobar* foobar_pointer = NULL;

So C++ is not always a super set of C :-).

Different types of declarations explained: C and C++ declarations can come in several forms, for example:

typedef struct { int A; } A; // unnamed class declaration (which gets a name from the typedef)
struct A { int i; }; // autonomous declaration
struct B { int i; } b; // non autonomous declaration

In these cases "struct" and "class" can be used interchangablily. Internally "struct" and "class" are he same (but with a different enum to classify them, see SgNameType and SgClassType). Clearly most C++ code uses autonomous declarations.

There are no uses of this IR node anywhere. All statements are derived from this SgClassDeclaration class.

This is a base class for all statements.

Member Function Documentation

◆ copy()

virtual SgNode* SgClassDeclaration::copy ( SgCopyHelp help) const
overridevirtual

This function clones the current IR node object recursively or not, depending on the argument.

This function performs a copy based on the specification of the input parameter. The input parameter is used to determin which data members are copied by reference and which are copied by value.

Parameters
help- If this argument is of type SgTreeCopy, then the IR node is cloned recursively. If its of type SgShallowCopy only the first level of the IR node is copied, everything else is left pointing to the the original IR node's object's data members.
Returns
a pointer to the new clone.

◆ replace_child()

virtual bool SgClassDeclaration::replace_child ( SgStatement target,

bool  extractListFromBasicBlock = false 
)
overrideprotectedvirtual

Private supporting function for low level SageIII rewrite interface.

This function implements special semantics for the insertion of a collection of statements in a block. If extractListFromBasicBlock is true then the statements in the block are extracts and placed into the same scope as the target position.

Returns
Returns bool.

◆ isInMemoryPool()

virtual bool SgClassDeclaration::isInMemoryPool ( )
overridevirtual

FOR INTERNAL USE This is used in internal tests to verify that all IR nodes are allocated from the heap.

The AST File I/O depends upon the allocation of IR nodes being from the heap, stack based or global IR nodes should not appear in the AST if it will be written out to a file and read back in. To enforce this concept, this function implements a test to verify that the IR node can be found on the heap and is part of a larger test of the whole AST. This test must pass before the AST can be written out to a file. This is part of a compromise in the design of the AST File I/O to support binary streaming of data to files; for performance. It is also rather difficult, but possible, to build a useful AST with IR nodes allocated on the stack or frm global scope, this test filters out such cased from being used with the AST File I/O mechanism.

◆ checkDataMemberPointersIfInMemoryPool()

◆ returnDataMemberPointers()

virtual std::vector<std::pair<SgNode*,std::string> > SgClassDeclaration::returnDataMemberPointers ( ) const
overridevirtual

FOR INTERNAL USE Returns STL vector of pairs of SgNode* and strings for use in AST tools

This functions is part of general support for many possible tools to operate on the AST. The forms a list of ALL IR node pointers used by each IR node, and is a supperset of the get_traversalSuccessorContainer(). It is (I think) less than the set of pointers used by the AST file I/O. This is part of work implemented by Andreas, and support tools such as the AST graph generation.

Warning
This function can return unexpected data members and thus the order and the number of elements is unpredicable and subject to change.
Returns
STL vector of pairs of SgNode* and strings

Reimplemented from SgDeclarationStatement.

Reimplemented in SgModuleStatement, SgDerivedTypeStatement, SgTemplateInstantiationDecl, and SgTemplateClassDeclaration.

◆ processDataMemberReferenceToPointers()

virtual void SgClassDeclaration::processDataMemberReferenceToPointers ( ReferenceToPointerHandler *  )
overridevirtual

FOR INTERNAL USE Processes pairs of references to SgNode* and strings for use in AST tools

This functions similar to returnDataMemberPointers() except that it passes references to a handler object. As a result there is FAR more damage that can be done by using this function, but it is type-safe. This is provided for support of internal tools that operate on the AST, e.g the AST Merge mechanism.

Warning
This function can return unexpected data members and thus the order and the number of elements is unpredicable and subject to change.

Reimplemented from SgDeclarationStatement.

Reimplemented in SgModuleStatement, SgDerivedTypeStatement, SgTemplateInstantiationDecl, and SgTemplateClassDeclaration.

◆ getChildIndex()

virtual long SgClassDeclaration::getChildIndex ( SgNode childNode) const
overridevirtual

FOR INTERNAL USE Returns a unique index value for the childNode in the list of children at this IR node.

This function returns a unique value for the input childNode in set of children at this IR node. Note that a negative value indicates that the input node is not a child. This is the basis for the implementation of the isChild(SgNode*) member function. Data members that are NULL in the IR node are counted internally (so that this function returns value that could be statically defined, and so are not dynamically determined).

Warning
The mapping on children to integer values could change from release to release of ROSE.
Returns
long

Reimplemented from SgDeclarationStatement.

Reimplemented in SgModuleStatement, SgDerivedTypeStatement, SgTemplateInstantiationDecl, and SgTemplateClassDeclaration.

◆ addRegExpAttribute()

SgClassDeclaration* SgClassDeclaration::addRegExpAttribute ( std::string  s,
AstRegExAttribute a 
)

Support for AST matching using regular expression.

This support is incomplete and the subject of current research to define RegEx trees to support inexact matching.

◆ get_scope()

SgScopeStatement* SgClassDeclaration::get_scope ( ) const
overridevirtual

Returns scope of current statement.

This functions returns a pointer to the inner most SgScopeStatement where the current statement is located. This is a function called after the parents have been set. It is not called by the EDG/SAGE interface and is only called after the SAGE AST has been built and the parent pointers set within a separate phase. Improtant exception: The SgFunctionParameterList should have as it's scope the SgFunctionDefinition, but it is a sibling of the SgFunctionDefinition (both the SgFunctionParameterList and the SgFunctionDefinition have the SgFunctionDeclaration as a parent. Thus the scope of the SgFunctionParameterList is computed to be the SgGlobal (global scope) most often; which is an error). So we handle this case explicitly.

Returns
Returns valid pointer to SgScopeStatement.

Reimplemented from SgStatement.

Member Data Documentation

◆ p_definition

SgClassDeclaration::p_definition
protected

This is the class definition (alway a valid pointer, except for explicitly marked forward declarations).

When this is a defining or nondefining declartion the p_definition pointer is always valid. However, as a separate rule, all forward declarations are both makred explicit as forward declarations AND have a NULL value for their p_definition pointer.

Definition at line 151875 of file Cxx_Grammar.h.

◆ p_from_template

SgClassDeclaration::p_from_template
protected

This records if the class declaration is associated with a template.

This boolean value is set to true if this is a non-template class nested in a templated class. We have an explicit IR node for template classes, but this is only flag to indicate that several template specific rules apply to the declaration of this class if the value is true. For example, the class will not be output unless it is transformed, then the required specialization is required for the parent templated class.
