Class VirtualClassDerivation

A class/struct derivation that is virtual. For example the derivation in the following code is a VirtualClassDerivation:

class MyClass : public virtual MyBaseClass {
  ...
};

Predicates

getAPrimaryQlClass

Gets the name of a primary CodeQL class to which this element belongs.

Inherited predicates

findRootCause	Gets the source of this element: either itself or a macro that expanded to this element.	from Element
fromSource	Holds if this element may be from source. This predicate holds for all elements, except for those in the dummy file, whose name is the empty string. The dummy file contains declarations that are built directly into the compiler.	from Element
getASpecifier	Gets a specifier (for example `public`) applied to the derivation.	from ClassDerivation
getBaseClass	Gets the class/struct from which we are actually deriving, resolving a typedef if necessary. For example, the base class in the following code would be `B`:	from ClassDerivation
getBaseType	Gets the type from which we are deriving, without resolving any typedef. For example, the base type in the following code would be `T`:	from ClassDerivation
getByteOffset	Gets the byte offset of the base class subobject relative to the start of the derived class object. Only holds for non-virtual bases, since the offset of a virtual base class is not a constant. Does not hold if the derived class is an uninstantiated template. See `Class.getVirtualBaseClassByteOffset` for offsets of virtual base classes.	from ClassDerivation
getDerivedClass	Gets the class/struct that is doing the deriving. For example, the derived class in the following code would be `D`:	from ClassDerivation
getEnclosingElement	Gets the closest `Element` enclosing this one.	from Element
getFile	Gets the primary file where this element occurs.	from Element
getIndex	Gets the index of the derivation in the derivation list for the derived class/struct (indexed from 0). For example, the index of the derivation of `B2` in the following code would be `1`: `struct D : B1, B2 { ... };`	from ClassDerivation
getLocation	Gets the location of the derivation.	from ClassDerivation
getParentScope	Gets the parent scope of this `Element`, if any. A scope is a `Type` (`Class` / `Enum`), a `Namespace`, a `BlockStmt`, a `Function`, or certain kinds of `Statement`.	from Element
getPrimaryQlClasses	Gets a comma-separated list of the names of the primary CodeQL classes to which this element belongs.	from ElementBase
hasSpecifier	Holds if the derivation has specifier `s`.	from ClassDerivation
isAffectedByMacro	Holds if this element is affected in any way by a macro. All elements that are totally or partially generated by a macro are included, so this is a super-set of `isInMacroExpansion`.	from Element
isFromTemplateInstantiation	Holds if this `Element` is a part of a template instantiation (but not the template itself).	from Element
isFromUninstantiatedTemplate	Holds if this `Element` is part of a template `template` (not if it is part of an instantiation of `template`). This means it is represented in the database purely as syntax and without guarantees on the presence or correctness of type-based operations such as implicit conversions.	from Element
isInMacroExpansion	Holds if this element comes from a macro expansion. Only elements that are entirely generated by a macro are included - for elements that partially come from a macro, see `isAffectedByMacro`.	from Element
isVirtual	Holds if the derivation is for a virtual base class.	from ClassDerivation
toString	Gets a textual representation of this element.	from ClassDerivation
