Class SiemensNamedVariableLookup
- Namespace
- Hi.NcParsers.EvaluationSyntaxs.Siemens
- Assembly
- HiMech.dll
Reads Sinumerik named program variables (_X_HOME) from
Vars.Named. Self-gates on the named-identifier key shape so the
evaluator's RuntimeVariableLookups
chain can fall through for other keys. Sibling of the Fanuc
VolatileVariableLookup with the same
single-step traceback: SiemensNamedVariableReadingSyntax
dict-merges every block's Vars.Named into the next block, so the
entry — if it exists — is on the current block or the immediately
previous one.
Stateless and dependency-free — instances are interchangeable.

Constructors
SiemensNamedVariableLookup()
Default constructor.
public SiemensNamedVariableLookup()
SiemensNamedVariableLookup(XElement)
Loads from an XML element produced by MakeXmlSource(string, string, bool). Stateless — no fields to deserialise.
public SiemensNamedVariableLookup(XElement src)
Parameters
srcXElement
Properties
XName
XML element name for Generators registration.
public static string XName { get; }
Property Value
Methods
Get(string, LazyLinkedListNode<SyntaxPiece>, IReadOnlyList<INcDependency>)
Returns the value of the variable identified by key
in the context of node and
dependencies, or null if the key is outside
this lookup's range or the value is vacant.
public double? Get(string key, LazyLinkedListNode<SyntaxPiece> node, IReadOnlyList<INcDependency> dependencies)
Parameters
keystringnodeLazyLinkedListNode<SyntaxPiece>dependenciesIReadOnlyList<INcDependency>
Returns
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.
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)
