Class VolatileVariableLookup

Namespace

Hi.NcParsers.EvaluationSyntaxs.Evaluation

Assembly

HiMech.dll

Reads Fanuc-style non-retained common variables (#100-#499) from Vars.Volatile. Self-gates the id range so the evaluator's RuntimeVariableLookups chain can fall through to the next lookup for out-of-range keys.

Single-step lookup: VolatileVariableReadingSyntax already dict-merges every block's Vars.Volatile into the next block, so the entry — if it exists — must be on the current block (when this lookup runs after the reader) or on the immediately previous block (when this lookup runs before the reader on the same block, which is the Fanuc preset's order — evaluator first, reader second). No arbitrary walk-back: such a walk would be defensive overkill given the reader's carry guarantee.

Stateless and dependency-free — instances are interchangeable. Reads stay decoupled from the reader (read side here; write side in the reader).

Constructors

VolatileVariableLookup()

Default constructor.

public VolatileVariableLookup()

VolatileVariableLookup(XElement)

Loads from an XML element produced by MakeXmlSource(string, string, bool). Stateless — no fields to deserialise.

public VolatileVariableLookup(XElement src)

Parameters

src XElement

Properties

XName

XML element name for Generators registration.

public static string XName { get; }

Property Value

string

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

key string

node LazyLinkedListNode<SyntaxPiece>

dependencies IReadOnlyList<INcDependency>

Returns

double?

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

baseDirectory string

The base directory for resolving relative paths

relFile string

The relative file path for the XML source

exhibitionOnly bool

if 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)

Parameters

factory XFactory
