Class SubBasicBlockCutNode

An abstract class that directs where in the control-flow graph a new SubBasicBlock must start. If a ControlFlowNode is an instance of this class, that node is guaranteed to be the first node in a SubBasicBlock. If multiple libraries use the SubBasicBlock library, basic blocks may be split in more places than either library expects, but nothing should break as a direct result of that.

Direct supertypes

Indirect supertypes

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
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
getAPrimaryQlClass

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

from ElementBase
getASuccessor

Gets a direct successor of this control-flow node, if any.

from ControlFlowNode
getATrueSuccessor

Gets a node such that the control-flow edge (this, result) may be taken when this expression is true.

from ControlFlowNode
getBasicBlock

Gets the BasicBlock containing this control-flow node.

from ControlFlowNode
getControlFlowScope

Gets the function containing this control-flow node.

from ControlFlowNode
getEnclosingElement

Gets the closest Element enclosing this one.

from Element
getEnclosingStmt

Gets the smallest statement containing this control-flow node.

from ControlFlowNode
getFile

Gets the primary file where this element occurs.

from Element
getLocation

Gets the primary location of this element.

from Element
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
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
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
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
toString

Gets a textual representation of this element.

from ElementBase
