Detailed Description

Plugin-facing surface for a Shader Graph project item.

The graph is stored as a single JSON document mirroring the schema the web-based Shader Graph editor round-trips with Kanzi Studio; plugins read and write that document directly.

The generated partial of this interface (in GeneratedPluginProjectItemInterfaces.cs) declares the PropertyTypes accessor; this hand-authored partial adds the JSON model accessors. SetModelJson(string) performs structural and semantic validation against the schema (required fields, id consistency, dangling edge endpoints, cycles, output-node count and graph-type match) and rejects the write via ShaderGraphValidationException when any check fails. Catalog-level concerns (whether the node-type IDs and port IDs exist in the editor's node catalog, type-correct edges) are not validated here and surface through the editor's compilation path on the next round-trip.

Member Function Documentation

◆ GetModelJson()

string? GetModelJson ( )

Gets the current graph model as a JSON string, or null if no model has been stored yet (e.g.

a freshly created Shader Graph item that has not yet been opened in the editor).

Returns
The graph model JSON, or null.

◆ SetModelJson()

void SetModelJson ( string json)

Replaces the graph model with the supplied JSON document.

The write is wrapped in an undo-able batch (one undo step), and if a Shader Graph editor window is open on this item the host posts a command.replaceGraph into the WebView2 so the editor mirrors the new state immediately.

Parameters
jsonA JSON document conforming to the Shader Graph model schema. Must not be null.
Exceptions
System.ArgumentNullExceptionjson is null.
ShaderGraphValidationExceptionjson is not a well-formed shader graph model document, or fails structural or semantic validation. The thrown instance's ShaderGraphValidationException.Errors list describes every detected problem.

◆ ValidateModelJson()

IReadOnlyList< ShaderGraphValidationError > ValidateModelJson ( string json)

Dry-run validation: parses json and reports every structural or semantic problem it detects, without writing the result back to the project.

Suitable for AI- or plugin-driven authoring loops that want to iterate on a candidate graph before committing.

Parameters
jsonThe candidate shader graph model JSON. Must not be null.
Returns
A possibly-empty list of ShaderGraphValidationError entries. An empty list means the JSON parsed and passed every check the host performs; a write through SetModelJson(string) with the same input will succeed (barring concurrent project mutations). A non-empty list describes the problems that would cause SetModelJson(string) to throw.
Exceptions
System.ArgumentNullExceptionjson is null.
