Detailed Description

This class represents the notion of an value (expression value).

For internal use only.

This is a base class for all value expressions.

Todo:

We should add a SgComplexValue IR nodes for C99 support of complex constants. At the moment these are internally represented as SgFloatValue, SgDoubleValue, or SgLongDoubleValue IR nodes.

This function builds and returns a copy of ordered container holding pointers to children of this node in a traversal. It is associated with the definition of a tree that is travered by the AST traversal mechanism; a tree that is embeded in the AST (which is a more general graph). This function is used within the implementation of the AST traversal and has a semantics may change in subtle ways that makes it difficult to use in user code. It can return unexpected data members and thus the order and the number of elements is unpredicable and subject to change.

Warning:

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

Returns:

Returns ordered STL Container of pointers to children nodes in AST.

virtual std::vector<std::string> SgValueExp::get_traversalSuccessorNamesContainer

(

)

[virtual]

FOR INTERNAL USE within ROSE traverals mechanism only.

This function builds and returns a copy of ordered container holding strings used to name data members that are traversed in the IR node. It is associated with the definition of a tree that is travered by the AST traversal mechanism; a tree that is embeded in the AST (which is a more general graph). This function is used within the implementation of the AST traversal and has a semantics may change in subtle ways that makes it difficult to use in user code. It can return unexpected data members and thus the order and the number of elements is unpredicable and subject to change.

Warning:

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

Each string is a name of a member variable holding a pointer to a child in the AST. The names are the same as used in the generated enums for accessing attributes in a traversal. The order is the same in which they are traversed and the same in which the access enums are defined. Therefore this method can be used to get the corresponding name (string) of an access enum which allows to produce more meaningful messages for attribute computations.

Returns:

Returns ordered STL container of names (strings) of access names to children nodes in AST.

[virtual]

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.

virtual std::vector<std::pair<SgNode*,std::string> > SgValueExp::returnDataMemberPointers

(

const [virtual]

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.

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.

const [virtual]

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:
