Class LoopSplitting :: AnalyzableLoopStmt

A loop where the body is guaranteed to be executed at least once, and hence can be unrolled in the control flow graph, or where the body is guaranteed to never be executed, and hence can be removed from the control flow graph.

Predicates

isUnroll	Holds if the body is guaranteed to be executed at least once. If not, the body is guaranteed to never be executed.
pruneLoopCondition	Holds if any step `pred --c--> _` should be pruned from the control flow graph.
start	Holds if the step `pred --c--> succ` should start the split.
stop	Holds if the step `pred --c--> succ` should stop the split.

Inherited predicates

controlsBlock	Holds if basic block `controlled` is controlled by this control flow element with conditional value `s`. That is, `controlled` can only be reached from the callable entry point by going via the `s` edge out of some basic block ending with this element.	from ControlFlowElement
fromLibrary	Holds if this element is from an assembly.	from Element
fromSource	Holds if this element is from source code.	from Element
getAChild	Gets a child of this element, if any.	from Element
getAChildExpr	Gets a child expression of this element, if any.	from ExprOrStmtParent
getAChildStmt	Gets a child statement of this element, if any.	from ExprOrStmtParent
getAControlFlowEntryNode	Gets a first control flow node executed within this element.	from ControlFlowElement
getAControlFlowExitNode	Gets a potential last control flow node executed within this element.	from ControlFlowElement
getAControlFlowNode	Gets a control flow node for this element. That is, a node in the control flow graph that corresponds to this element.	from ControlFlowElement
getALocation	Gets a location of this element, including sources and assemblies.	from Stmt
getAPrimaryQlClass	Gets the name of a primary CodeQL class to which this element belongs.	from Element
getAReachableElement	Gets an element that is reachable from this element.	from ControlFlowElement
getAssembly	Gets the assembly that this element was compiled into.	from ControlFlowElement
getBody	Gets the body of this loop statement.	from LoopStmt
getChild	Gets the `i`th child of this element (zero-based).	from ExprOrStmtParent
getChildExpr	Gets the `i`th child expression of this element (zero-based).	from ExprOrStmtParent
getChildStmt	Gets the `i`th child statement of this element (zero-based).	from ExprOrStmtParent
getCondition	Gets the condition of this loop statement, if any.	from LoopStmt
getEnclosingCallable	Gets the enclosing callable of this statement.	from Stmt
getFile	Gets the file containing this element.	from Element
getIndex	Gets the index of this element among its parent’s other children (zero-based).	from Element
getLanguage	Gets the “language” of this program element, as defined by the extension of the filename. For example, C# has language “cs”, and Visual Basic has language “vb”.	from Element
getLocation	Gets the location of this element. Where an element has locations in source and assemblies, choose the source location. If there are multiple assembly locations, choose only one.	from Element
getNumberOfChildren	Gets the number of children of this element.	from Element
getParent	Gets the parent of this element, if any.	from Element
getPrimaryQlClasses	Gets a comma-separated list of the names of the primary CodeQL classes to which this element belongs.	from Element
isGlobal	Holds if this statement is a global statement.	from Stmt
isLive	Holds if this element is live, that is this element can be reached from the entry point of its enclosing callable.	from ControlFlowElement
reachableFrom	Holds if the current element is reachable from `src`.	from ControlFlowElement
stripSingletonBlocks	Gets the singleton statement contained in this statement, by removing enclosing block statements.	from Stmt
toString	Gets a textual representation of this element.	from Stmt
toStringWithTypes	Gets the full textual representation of this element, including type information.	from Element
