A data-type resolved from an associated TypeUnion or TypeStruct.
A parent refers to either: 1) A union 2) A structure that is an effective union (1 field filling the entire structure) OR 3) A pointer to a union/structure
This object represents a data-type that is resolved via analysis from the parent data-type. The resolved data-type can be either: 1) A specific field of the parent (if the parent is not a pointer) 2) A pointer to a specific field of the underlying union/structure (if the parent is a pointer) 3) The parent data-type itself (either a pointer or not) The fieldNum (if non-negative) selects a particular field of the underlying union/structure. If the parent is a pointer, the resolution is a pointer to the field. If the parent is not a pointer, the resolution is the field itself. A fieldNum of -1 indicates that the parent data-type itself is the resolution.
| ghidra::ResolvedUnion::ResolvedUnion | ( | Datatype * | unresType | ) |
Construct a data-type that resolves to itself.
The original data-type must either be a union, a partial union, a structure with a single field, an array with a single element, or a pointer to one of these data-types. The object is set up initially to resolve to the parent.
| unresType | is the original unresolved data-type |

| ghidra::ResolvedUnion::ResolvedUnion | ( | Datatype * | unresType, |

| TypeFactory & | typegrp | ||
| ) |
Construct a resolution with a specific field number.
| unresType | is the data-type that needs resolution |
| fldNum | is the index of the particular field to resolve to (or -1 to resolve to unresType) |
| typegrp | is a TypeFactory used to construct the resolved data-type of the field |
