FastMoq uses this wrapper instead of exposing raw renderer internals directly because bUnit 2 changed the shape of the renderer state it stores for rendered components. Consumers should prefer GetOrCreateRenderedComponent(Type) or GetOrCreateRenderedComponent<T>() over reflecting on renderer state objects themselves.

Constructors

ComponentState(object?, BunitRenderer, IRenderedComponent<IComponent>?)

Initializes a new instance of the ComponentState class.

Declaration

public ComponentState(object? obj, BunitRenderer renderer, IRenderedComponent<IComponent>? rootComponent = null)

Parameters

Type	Name	Description
object	obj	The raw renderer state object.
BunitRenderer	renderer	The renderer.
IRenderedComponent<IComponent>	rootComponent	The rendered root component used for nested component lookups when needed.

Exceptions

Type	Condition
ArgumentNullException	renderer

Properties

Component

Gets the component.

Declaration

public IComponent? Component { get; }

Property Value

Type	Description
IComponent	The component.

ComponentId

Gets the component identifier.

Declaration

public int ComponentId { get; }

Property Value

Type	Description
int	The component identifier.

ComponentType

Gets or sets the type of the component.

Declaration

protected Type ComponentType { get; set; }

Property Value

Type	Description
Type	The type of the component.

CurrentRenderTree

Gets the current render tree.

Declaration

public RenderTreeBuilder? CurrentRenderTree { get; }

Property Value

Type	Description
RenderTreeBuilder	The current render tree.

IsComponentBase

Gets a value indicating whether this instance is component base.

Declaration

public bool IsComponentBase { get; }

Property Value

Type	Description
bool	`true` if this instance is component base; otherwise, `false`.

ParentComponentState

Gets the state of the parent component.

Declaration

public ComponentState? ParentComponentState { get; }

Property Value

Type	Description
ComponentState	The state of the parent component.

Methods

GetOrCreateRenderedComponent(Type)

Gets the or create rendered component.

Declaration

public IRenderedComponent<IComponent>? GetOrCreateRenderedComponent(Type type)

Parameters

Type	Name	Description
Type	type	The type.

Returns

Type	Description
IRenderedComponent<IComponent>	System ofNullable<IRenderedComponent<IComponent>> of the or create rendered component.

Remarks

This method understands both direct rendered-component state values and the fallback lookup path required by bUnit 2's renderer state dictionary.

GetOrCreateRenderedComponent<T>()

Gets the or create rendered component.

Declaration

public virtual IRenderedComponent<T>? GetOrCreateRenderedComponent<T>() where T : ComponentBase

Returns

Type	Description
IRenderedComponent<T>	System ofNullable<IRenderedComponent<T>> of the or create rendered component.

Type Parameters

Name	Description
T	The component type.

Examples

var state = GetAllComponents<FetchData>().First().Value as ComponentState<FetchData>;
var rendered = state?.GetOrCreateRenderedComponent<FetchData>();
