Class GeneralMechanism

Namespace
Hi.Mech
Assembly
HiMech.dll

General Mechanism: the pure-topology IMechanism — an assembly, a root anchor and the solids on the anchors, nothing else. It is the file type of the Mechanism Builder (.GeneralMechanism) and the side file a machine file points at for its topology.

public class GeneralMechanism : IMakeXmlSource, IMechanism, ITopo, IGetAsmb, IGetAnchoredDisplayeeList, IGetAnchorToSolidDictionary, IAnchoredDisplayee, IGetAnchor, IGetTopoIndex, IDisplayee, IExpandToBox3d
Inheritance

Remarks

The XML IO is according to self-contained principle; the three members are read and written by MechanismXml.

Constructors

GeneralMechanism()

Initializes a new instance of the GeneralMechanism class.

public GeneralMechanism()

GeneralMechanism(Asmb, Anchor, Dictionary<Anchor, Solid>)

Initializes a mechanism from its three members, adopting the instances as they are — the way an assembly seeded by ChainCodeUtil or read by MechanismXml becomes a stand-alone mechanism.

public GeneralMechanism(Asmb asmb, Anchor root, Dictionary<Anchor, Solid> anchorToSolid)

Parameters

asmb Asmb

The key assembly.

root Anchor

The root anchor, inside asmb.

anchorToSolid Dictionary<Anchor, Solid>

The solid dictionary, keyed by anchors of asmb; kept as the live instance.

Exceptions

ArgumentNullException

Any member is null.

ArgumentException

The root anchor is not inside the assembly.

GeneralMechanism(XElement, string, IProgress<IMessage>)

Initializes a new instance of the GeneralMechanism class from XML.

public GeneralMechanism(XElement src, string baseDirectory, IProgress<IMessage> progress)

Parameters

src XElement

The XML element containing the mechanism data.

baseDirectory string

The base directory for resolving relative file paths.

progress IProgress<IMessage>

Progress reporter for diagnostic messages emitted during construction.

Properties

AnchorToSolid

Gets the dictionary mapping anchors to their corresponding solids.

public Dictionary<Anchor, Solid> AnchorToSolid { get; }

Property Value

Dictionary<Anchor, Solid>

Asmb

Gets the assembly containing the mechanism components.

public Asmb Asmb { get; }

Property Value

Asmb

Root

Gets the root anchor of the mechanism.

public Anchor Root { get; }

Property Value

Anchor

XName

Name for XML IO.

public static string XName { get; }

Property Value

string

Methods

Display(Bind)

Display function called in DispEngine rendering loop.

public void Display(Bind bind)

Parameters

bind Bind

Bind with DispEngine. See Bind.

ExpandToBox3d(ref box3d_t)

Expands the destination box. This function is usually used to compute the bounding box of elements. box3d_t is a value type, so the destination is passed by reference (the C++ expand_to_box3d(box3&) shape); an implementation writes dst = dst.Expanded(...) or forwards ref dst to its parts.

public void ExpandToBox3d(ref box3d_t dst)

Parameters

dst box3d_t

Destination box, expanded in place

GetAnchor()

Get key anchor. (i.e. root anchor)

public Anchor GetAnchor()

Returns

Anchor

key anchor

GetAnchorToSolidDictionary()

Gets a dictionary that maps Anchor objects to their corresponding Solid objects.

public Dictionary<Anchor, Solid> GetAnchorToSolidDictionary()

Returns

Dictionary<Anchor, Solid>

A dictionary where keys are anchors and values are their associated solids.

GetAnchoredDisplayeeList()

Gets a list of anchored displayable objects.

public List<IAnchoredDisplayee> GetAnchoredDisplayeeList()

Returns

List<IAnchoredDisplayee>

A list of IAnchoredDisplayee objects

GetAsmb()

Gets the key asmb.

public Asmb GetAsmb()

Returns

Asmb

The key asmb.

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 and chains Reg(factory) on dependents. Idempotent.

public static void Reg(XFactory factory = null)

Parameters

factory XFactory
