Predicates

getAPrimaryQlClass	Gets the name of a primary CodeQL class to which this element belongs.
getArrayBase	Gets the expression being subscripted.
getArrayOffset	Gets the expression giving the index.

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
getAChild	Gets a child of this expression.	from Expr
getAFalseSuccessor	Gets a node such that the control-flow edge `(this, result)` may be taken when this expression is false.	from ControlFlowNode
getAPredecessor	Gets a direct predecessor of this control-flow node, if any.	from ControlFlowNode
getASuccessor	Gets a direct successor of this control-flow node, if any.	from ControlFlowNode
getATemplateArgument	Gets a template argument for this call.	from FunctionCall
getATemplateArgumentKind	Gets a template argument value for this call.	from FunctionCall
getATrueSuccessor	Gets a node such that the control-flow edge `(this, result)` may be taken when this expression is true.	from ControlFlowNode
getActualType	Gets the type of this expression, after any implicit conversions and explicit casts, and after resolving typedefs.	from Expr
getAnArgument	Gets an argument for this call. To get the qualifier of this call, if any, use `getQualifier()`.	from Call
getAnArgumentSubExpr	Gets a subexpression of the argument at position `index`. If the argument itself contains calls, such calls will be considered leaves in the expression tree. The qualifier of the call, if any, is not considered to be an argument.	from Call

getArgument	Gets the nth argument for this call.	from Call
getBasicBlock	Gets the `BasicBlock` containing this control-flow node.	from ControlFlowNode
getChild	Gets the nth child of this expression.	from Expr
getControlFlowScope	Gets the function containing this control-flow node.	from Expr
getConversion	Gets the conversion associated with this expression, if any.	from Expr

getExplicitTemplateArgumentKind	Gets the nth explicit template argument value for this call.	from FunctionCall
getExplicitlyConverted	Gets this expression with all of its explicit casts, but none of its implicit casts. More precisely this takes conversions up to the last explicit cast (there may be implicit conversions along the way), but does not include conversions after the last explicit cast.	from Expr
getFile	Gets the primary file where this element occurs.	from Element
getFullyConverted	Gets the fully converted form of this expression, including all type casts and other conversions.	from Expr
getImplicitDestructorCall	Gets the `n`th compiler-generated destructor call that is performed after this expression, in order of destruction.	from Expr
getImplicitlyConverted	Gets this expression with all of its initial implicit casts, but none of its explicit casts. More precisely, this takes all implicit conversions up to (but not including) the first explicit cast (if any).	from Expr
getLocation	Gets the location of this expression.	from Expr
getNameQualifier	Gets the name qualifier associated with this element. For example, the name qualifier of `N::f()` is `N`.	from NameQualifiableElement

getParentWithConversions	Gets the parent of this expression, if any, in an alternative syntax tree that has `Conversion`s as part of the tree.	from Expr
getPrecedence	Gets the precedence of the main operator of this expression; higher precedence binds tighter.	from Call
getPrimaryQlClasses	Gets a comma-separated list of the names of the primary CodeQL classes to which this element belongs.	from ElementBase
getQualifier	Gets the expression to the left of the function name or function pointer variable name.	from Call
getTarget	Gets the function called by this call.	from FunctionCall
getTargetType	Gets the `RoutineType` of the call target as visible at the call site. For constructor calls, this predicate instead gets the `Class` of the constructor being called.	from FunctionCall
getTemplateArgument	Gets the nth template argument for this call (indexed from 0).	from FunctionCall
getTemplateArgumentKind	Gets the nth template argument value for this call (indexed from 0).	from FunctionCall
getType	Gets the type of this expression, that is, the return type of the function being called.	from FunctionCall

getUnderlyingType	Gets the type of this expression after typedefs have been resolved.	from Expr
getUnspecifiedType	Gets the type of this expression after specifiers have been deeply stripped and typedefs have been resolved.	from Expr
getValue	Gets the value of this expression, if it is a constant.	from Expr
getValueCategoryString	Gets a string representation of the value category of the expression. This is intended only for debugging. The possible values are:	from Expr
getValueText	Gets the source text for the value of this expression, if it is a constant.	from Expr
hasChild	Holds if e is the nth child of this expression.	from Expr
hasConversion	Holds if this expression has a conversion.	from Expr
hasExplicitConversion	Holds if this expression has an explicit conversion.	from Expr
hasGlobalQualifiedName	Holds if this element has a globally qualified name. For example, `::x` is globally qualified. It is used to refer to `x` in the global namespace.	from NameQualifiableElement
hasImplicitConversion	Holds if this expression has an implicit conversion.	from Expr
hasImplicitTemplateArguments	Holds if any template arguments for this call are implicit / deduced.	from FunctionCall
hasLValueToRValueConversion	Holds if this expression has undergone an lvalue-to-rvalue conversion to extract its value. for example: `y = x;` The `VariableAccess` for `x` is a prvalue, and `hasLValueToRValueConversion()` holds because the value of `x` was loaded from the location of `x`. The `VariableAccess` for `y` is an lvalue, and `hasLValueToRValueConversion()` does not hold because the value of `y` was not extracted.	from Expr
hasQualifier	Holds if this call has a qualifier.	from Call
hasSuperQualifiedName	Holds if this element has a `__super`-qualified name. For example: `__super::get()`. Note: `__super` is non-standard C++ extension, only supported by some C++ compilers.	from NameQualifiableElement
hasTemplateArgumentList	Holds if a template argument list was provided for this call.	from FunctionCall
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
isCompilerGenerated	Holds if this is an auxiliary expression generated by the compiler.	from Expr
isCondition	Holds if this node is the top-level expression of a conditional statement, meaning that `this.getATrueSuccessor()` or `this.getAFalseSuccessor()` will have a result.	from ControlFlowNode
isConstant	Holds if this expression has a value that can be determined at compile time.	from Expr
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
isGLValueCategory	Holds if this expression is a glvalue. A glvalue is either an lvalue or an xvalue.	from Expr
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
isLValue	Holds if this expression is an lvalue, in the sense of having an address.	from Expr
isLValueCategory	Holds if this expression is an lvalue. An lvalue is an expression that represents a location, rather than a value. See [basic.lval] for more about lvalues.	from Expr
isOnlyFoundByADL	Holds if the target of this function call was found by argument-dependent lookup and wouldn’t have been found by any other means.	from FunctionCall
isPRValueCategory	Holds if this expression is a prvalue. A prvalue is an expression that represents a value, rather than a location. See [basic.lval] for more about prvalues.	from Expr
isParenthesised	Holds if this expression is parenthesised.	from Expr
isPure	Holds if this expression is side-effect free (conservative approximation). This predicate cannot be overridden; override mayBeImpure() instead.	from Expr
isRValueCategory	Holds if this expression is an rvalue. An rvalue is either a prvalue or an xvalue.	from Expr
isUnevaluated	Holds if this expression will not be evaluated because of its context, such as an expression inside a sizeof.	from Expr
isVirtual	Holds if this is a call to a virtual function.	from FunctionCall
isXValueCategory	Holds if this expression is an xvalue. An xvalue is a location whose lifetime is about to end (e.g. an rvalue reference returned from a function call). See [basic.lval] for more about xvalues.	from Expr
mayBeFromImplicitlyDeclaredFunction	Holds if this expression could be the return value of an implicitly declared function.	from Call
mayBeGloballyImpure	Holds if it is possible that the expression may be impure. If we are not sure, then it holds. Unlike `mayBeImpure()`, this predicate does not consider modifications to temporary local variables to be impure. If you call a function in which nothing may be globally impure then the function as a whole will have no side-effects, even if it mutates its own fresh stack variables.	from FunctionCall
mayBeImpure	Holds if it is possible that the expression may be impure. If we are not sure, then it holds.	from FunctionCall
passesByReference	Holds if this call passes the variable accessed by `va` by reference as the `i`th argument. The qualifier of a call to a member function is `i = -1`.	from Call
passesByReferenceNonConst	Holds if this call passes the variable accessed by `va` by reference to non-const data as the `i`th argument. The qualifier of a call to a member function is `i = -1`.	from Call
toString	Gets a textual representation of this function call.	from FunctionCall
