LoopStruct

final class LoopStruct extends ControlStruct

ControlStruct for explicit loop (do n ; do times; do while ; do until…).

Fields

body

public TapList<ControlStruct> body

exitArrow

public FGArrow exitArrow

loopArrow

public FGArrow loopArrow

Constructors

LoopStruct

protected LoopStruct(Block block)

Methods

addControlStruct

protected void addControlStruct(ControlStruct struct, FGArrow arrow)

dump

public void dump(int indent)

exitArrowsOf

protected TapList<FGArrow> exitArrowsOf()

generateTree

protected void generateTree(boolean delayGoto, TapList<TapTriplet<Tree, Tree, Integer>> toFutureIncludes, TapList<Tree> fileUserHelpStrings)

(Recursive) final regeneration of the structured Tree.

insertLetStructure

protected void insertLetStructure()

(Recursive) Inserts Let structures into the tree of ControlStruct’s to reflect nested local SymbolTable’s.

insertMultiDirStructure

protected void insertMultiDirStructure()

preGenerateTree

protected TapList<FGArrow> preGenerateTree(TapList<FGArrow> naturalArrows, TapList<TapTriplet<Tree, Tree, Integer>> toFutureIncludes, TapList<Tree> fileUserHelpStrings, TapList<ControlStruct> enclosingStructs, boolean skipSubUnits)

(Recursive) preparation before tree regeneration. Labels the arrows that need explicit jumps, prepares the skeleton of the future Tree.

Returns

a TapList of FGArrow

propagateNaturalFlow

protected TapList<FGArrow> propagateNaturalFlow()

(Recursive) precomputation of the “naturalFlow: info: the TapList of FGArrow that would naturally flow out of this ControlStruct, i.e. without any additional explicit jump.

propagateNaturalNext

protected void propagateNaturalNext(Block naturalNext)

(Recursive) precomputation of the “naturalNext” info: the next Block reached by natural flow from each ControlStruct.

reorderBody

protected void reorderBody()

(Recursive) Orders the lists of control structures inside, following all available indications on position (here: controlStructBlock ranks…).

toString

public String toString()
