Detailed Description

This class represents the notion of a unary operator. It is derived from a SgExpression because operators are expressions.

There are no uses of this IR node anywhere.  All expressions

are derived from this IR node to build derived classes. Example unary operators include unary minus, unary plus, the address operator, etc.

This is a base class for all unary operators.

Member Enumeration Documentation

enum SgUnaryOp::Sgop_mode

Enum value defines operators as prefix or postfix, as appropriate, e.g. operator++().

This enum type provides support for specification of prefix/postfix operators such as operator++() using a simpler mechanism thatn that provided by C++. See C++ standard for details of specification of prefix and postfix operators.

There should be an additional value added to support unknown setting (with value 0)

Constructor & Destructor Documentation

SgUnaryOp::SgUnaryOp ( const SgUnaryOpStorageClass & source)

SgUnaryOp::~SgUnaryOp ( )

virtual

This is the destructor.

Only the Sg_File_Info object can be deleted in this object.

SgUnaryOp::SgUnaryOp	(	Sg_File_Info *	startOfConstruct = `NULL`,
		SgExpression *	operand_i = `NULL`,
		SgType *	expression_type = `NULL`
	)

This is the constructor.

This constructor builds the SgUnaryOp base class.

Parameters

startOfConstruct	represents the position in the source code
operand	represents the operand to which the operator is applied
expression_type	represents the type of the return value of the operator

Member Function Documentation

virtual SgNode* SgUnaryOp::copy ( SgCopyHelp & help) const

virtual

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.

It appears the the copy functions don't set the parents of anything that they do a deep copy of! This can cause AST tests to fail. In particular some functions that require the parent pointers to be valid will return NULL pointers (e.g. SgInitializedName::get_declaration()). It might be that we should allow this to be done as part of the SgCopyHelp::clone function or perhaps another member function of SgCopyHelp would be useful for this support. It is not serious if the AST post processing is done since that will set any NULL pointers that are found within its traversal.

Exceptions

none	No exceptions are thrown by this function.

Reimplemented from SgExpression.

Reimplemented in SgUserDefinedUnaryOp, SgConjugateOp, SgImagPartOp, SgRealPartOp, SgThrowOp, SgCastExp, SgBitComplementOp, SgPlusPlusOp, SgMinusMinusOp, SgAddressOfOp, SgPointerDerefExp, SgNotOp, SgUnaryAddOp, SgMinusOp, and SgExpressionRoot.

SgUnaryOp::length ( ) const

Returns number of operands (virtual function)

 Returns number of operands (all unary operators return value = 1).

This function is not used and is not a defined part a minumal interface for Sage III.

Deprecated:: This function is not used.

Returns: Returns int

SgUnaryOp::empty ( ) const

Returns true if number of operands is zero, else false.

This function returns boolean value given by (length() == 0). This function is not used and is not a defined part a minumal interface for Sage III.

Deprecated:: This function is not used.

Returns: Returns bool

SgUnaryOp::get_next ( int & n) const

Returns next operand (virtual function)

 This function returns the next operand and is part of an

older iterator interface within Sage II which didn't use STL, but implemented iterators for the operands (since their is only one for a unary operator and two for a binary operator we don't support such an iterator interface within Sage III. The goal of Sage III is a minimal easily maintained interface. This function is not used and is not a defined part a minumal interface for Sage III.

FOR INTERNAL USE within ROSE traverals mechanism only.

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> SgUnaryOp::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 bool SgUnaryOp::isInMemoryPool ( )

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> > SgUnaryOp::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.

virtual long SgUnaryOp::getChildIndex ( SgNode * childNode) 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: long

Member Data Documentation

SgUnaryOp::p_operand_i

protected

This is the operand associated with the unary operator.

Every unary operator is applied to a single operand, this variable stores the operand to which the unary operator is applied.

Definition at line 171260 of file Cxx_Grammar.h.

SgUnaryOp::p_expression_type

protected

This SgType is the type of the operator (function type).

The type is now computed where possible (in all cases except

for SgCastExp). This allows us to save space and avoid having explicitly stored values be unset or set incorrectly.

Deprecated:: This is no longer used (except for SgCastExp).

Todo:: This value is only used for the SgCastExp, we will move it to that IR node when we are ready to change the interface for the SgExpressions (and SgUnaryExp IR nodes).

Definition at line 171264 of file Cxx_Grammar.h.

SgUnaryOp::p_mode

protected

This SgType is the type of the operator (function type).

This variable records the prefix vs. postfix semantics of the operator

since the syntax of "operator++" cannot readily do so. This approach is simpiler to interogate than the C++ syntax for distingishing prefix vs. postfix.
