Indirect_Partial_Operand

class Indirect_Partial_Operand (abstract, logical)

Access to a subobject of a dereferenced object: obj->subobject. Subclasses distinguish: kind of subobject, read/write/address

Implemented interfaces:

• implements Partial_Operand_Interface

Direct parents:

• inherits Indirect_Operand

Ancestor classes and implemented interfaces:

Execution_Node, Indirect_Operand, Logical_IR_Root, Operand, Partial_Operand_Interface

Direct child classes:

• subclass Indirect_Pointer_To_Member_Operand

• subclass Indirect_Field_Operand

• subclass Indirect_Array_Element_Operand

• subclass Indirect_Multi_Array_Element_Operand

Field	Kind	Type	Description
The_Object (from Operand)	semantic	interface General_Object_Interface	Affected object (direct case) or pointer (indirect case). For address operands, this can also be a routine. WARNING: because the meaning of this field is drastically different between direct operands and indirect operands, it is usually wrong to access this field without a preceding check of operand type!
Its_Type (from Operand)	semantic	class Type	The type of the operand. WARNING: For address operands, this field returns the pointed-to-type. That is, for int i, the operand &i will report Its_Type=int. Code using this field must check the read/write/address kind to avoid bugs! WARNING: For Field_Operand_Interface and Pointer_To_Member_Operand_Interface accesses, this is the declared type of the accessed member. Qualifiers (const, volatile) that the access inherits from an enclosing object are not part of it: for volatile struct S s;, the Direct_Field_Operand s.field has the declared type of field, although the access is volatile (C11 6.5.2.3, C++ [expr.ref]). Array elements are not affected, since qualifiers of an array type are already normalized onto the element type.
