Class SiemensLoopIterationDependency
- Namespace
- Hi.NcParsers.Dependencys.Siemens
- Assembly
- HiMech.dll
Watchdog shared by all four Siemens loop constructs
(WHILE/ENDWHILE, FOR/ENDFOR, REPEAT/UNTIL,
LOOP/ENDLOOP) — construct-neutral by design, unlike the Fanuc
sibling (FanucWhileDoIterationDependency) which
only has WHILE to guard. Same “soft-cap + runtime counter +
session-init ISessionResettable” shape.
Siemens loop constructs carry no LoopId, so the counter key is
(FileName, BeginLineNo) — the loop-entry line recorded in the
active frame identifies the construct uniquely within its file, and
the file path isolates identically-numbered lines across files (and
across inlined subprograms).
The consuming syntax
(SiemensLoopSyntax) counts at
the back-jump step (the loop terminator / falsy UNTIL), so a
loop whose condition is false from the outset consumes zero
iterations. Above MaxIterationsPerLoop the terminator
warns SiemensLoop--IterationLimitExceeded, pops the frame and
falls through. A missing dependency disables the cap for the
condition-bearing constructs (Fanuc parity) but hard-blocks the
ENDLOOP back-jump — LOOP has no exit condition, so an
uncapped back-jump would hang the pipeline deterministically.

Constructors
SiemensLoopIterationDependency()
Initializes a new instance with the default limit and an empty counter.
public SiemensLoopIterationDependency()
SiemensLoopIterationDependency(XElement)
Loads MaxIterationsPerLoop from XML produced by MakeXmlSource(string, string, bool); absent element falls back to DefaultMaxIterationsPerLoop.
public SiemensLoopIterationDependency(XElement src)
Parameters
Fields
DefaultMaxIterationsPerLoop
Default for MaxIterationsPerLoop — matches the Fanuc WHILE default: loops are the legitimate iteration primitive (drill grids, calibration sweeps), so the cap is generous while still catching runaways in a tractable time.
public const int DefaultMaxIterationsPerLoop = 10000
Field Value
Properties
CountByLoop
Per-loop hit counter keyed by (FileName, BeginLineNo).
Runtime-only; not serialised. Cleared by OnSessionReset()
on the session-init edge.
public Dictionary<(string FileName, int BeginLineNo), int> CountByLoop { get; }
Property Value
MaxIterationsPerLoop
Soft cap on back-jumps for any single (FileName, BeginLineNo)
pair. Above this the terminator block emits
SiemensLoop–IterationLimitExceeded, pops the frame and
falls through.
public int MaxIterationsPerLoop { get; set; }
Property Value
XName
XML element name used to register this dependency with XFactory.
public static string XName { get; }
Property Value
Methods
MakeXmlSource(string, string, bool)
Creates an XML representation of the object. This method may also generate additional resources such as related files.
public XElement MakeXmlSource(string baseDirectory, string relFile, bool exhibitionOnly)
Parameters
baseDirectorystringThe base directory for resolving relative paths
relFilestringThe relative file path for the XML source
exhibitionOnlyboolif true, the extended file creation is suppressed.
Returns
- XElement
An XML element representing the object's state
Remarks
For the demand of easy moving source folder (especially project folder) without configuration file path corruption, the relative file path is applied.
The baseDirectory is typically the folder at the nearest configuration file folder.
Since the folder can be moving with the configuration file.
OnSessionReset()
Clears CountByLoop; leaves MaxIterationsPerLoop untouched.
public void OnSessionReset()
Reg(XFactory)
Registers this type's deserializer with the given XFactory
(or Default when factory is
null). Idempotent.
public static void Reg(XFactory factory = null)
Parameters
