SgType Class Reference

Description

This class represents the base class for all types.

There are no uses of this IR node anywhere. All SgType based IR nodes are derived from this SgType class.

Discussion of get_base_type() and findBaseType():

1. fileBaseType() will recursively strip away all typedefs, reference, pointers, arrays, and modifiers
2. get_base_type() is a member function on some IR nodes derived from SgType and returns the non-recursively striped (immediate) type under the typedefs, reference, pointers, arrays, modifiers, etc.

Note that the typedefs for which the current SgType is the base type are stored in a list. There is a special IR node (SgTypedefSeq) to maintain this list (which is internally an STL list). We could also store pointers to other SgType IR nodes where pointers and references have been taken to the current IR node, but currently only typedefs are stored explicitly. As a result of storing the typedefs, the builtin types store the list for most SgType IR nodes (since ther is only a single SgType IR node for most SgType derived classes). We could imagine storing the SgTypedefSeq as static data members of the derived SgType classes, but this would not work since then all SgNamedType IR nodes would share the same list of typedefs. So this is the correct location for this list.

Member Function Documentation

copy()

virtual SgNode* SgType::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.

isInMemoryPool()

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.

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.

returnDataMemberPointers()

virtual std::vector<std::pair<SgNode*,std::string> > SgType::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

processDataMemberReferenceToPointers()

virtual void SgType::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.

getChildIndex()

virtual long SgType::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

addRegExpAttribute()

SgType* SgType::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_attributeMechanism()

AstAttributeMechanism * SgType::get_attributeMechanism ( ) const

overridevirtual

FOR INTERNAL USE Access function; if an attribute exists then a pointer to it is returned, else error.

This is an access function used for getting the interally held pointer to a valid AstAttributeMechanism. It provides access to lower level functionality of the AstAttributeMechanism, put is mostly of use to internal tools.

Reimplemented from SgNode.

set_attributeMechanism()

void SgType::set_attributeMechanism ( AstAttributeMechanism *  a )

overridevirtual

FOR INTERNAL USE Access function; sets poiner to value AstAttributeMechanism.

This is an access function used for setting the interally held pointer to a valid AstAttributeMechanism.

Reimplemented from SgNode.
