# Inspect class






    *[<Null safety>](https://dart.dev/null-safety)*



<p><a href="../package-fuchsia_inspect_inspect/Inspect-class.md">Inspect</a> exposes a structured tree of internal component state.</p>
<p>The <a href="../package-fuchsia_inspect_inspect/Inspect-class.md">Inspect</a> object maintains a hierarchy of <a href="../package-fuchsia_inspect_inspect/Node-class.md">Node</a> objects whose data are
exposed for reading by specialized tools such as iquery.</p>
<p>The classes exposed by this library do not support reading.</p>




## Constructors

[Inspect](../package-fuchsia_inspect_inspect/Inspect/Inspect.md) ()

Returns a singleton <a href="../package-fuchsia_inspect_inspect/Inspect-class.md">Inspect</a> instance at root.inspect   _factory_

[Inspect.forTesting](../package-fuchsia_inspect_inspect/Inspect/Inspect.forTesting.md) ([FakeVmoHolder](../package-fuchsia_inspect_testing/FakeVmoHolder-class.md) vmo)

Returns a new <a href="../package-fuchsia_inspect_inspect/Inspect-class.md">Inspect</a> object at root.inspect backed by a fake VMO
intended for unit testing inspect integrations, so that they can run as
host tests.   _factory_


## Properties

##### [hashCode](../package-fuchsia_inspect_inspect/Inspect/hashCode.md) &#8594; int



The hash code for this object.  
_read-only, inherited_



##### [health](../package-fuchsia_inspect_inspect/Inspect/health.md) &#8594; HealthNode



The health <a href="../package-fuchsia_inspect_inspect/Node-class.md">Node</a> of this Inspect tree.  
_read-only_



##### [root](../package-fuchsia_inspect_inspect/Inspect/root.md) &#8594; [Node](../package-fuchsia_inspect_inspect/Node-class.md)?



The root <a href="../package-fuchsia_inspect_inspect/Node-class.md">Node</a> of this Inspect tree.  
_read-only_



##### [runtimeType](../package-fuchsia_inspect_inspect/Inspect/runtimeType.md) &#8594; Type



A representation of the runtime type of the object.  
_read-only, inherited_





## Methods

##### [noSuchMethod](../package-fuchsia_inspect_inspect/Inspect/noSuchMethod.md)(Invocation invocation) dynamic



Invoked when a non-existent method or property is accessed.  
_inherited_



##### [onDemand](../package-fuchsia_inspect_inspect/Inspect/onDemand.md)(String name, OnDemandRootFn rootNodeCallback) void



Mounts an <a href="../package-fuchsia_inspect_inspect/Inspect-class.md">Inspect</a> file at <name>.inspect whose contents are
dynamically created by rootNodeCallback on each read.</name>  




##### [serve](../package-fuchsia_inspect_inspect/Inspect/serve.md)([Outgoing](../package-fuchsia_services_services/Outgoing-class.md) outgoing) void



Attaches the inspect to the outgoing diagnostics/debug dir.  




##### [toString](../package-fuchsia_inspect_inspect/Inspect/toString.md)() String

## Static Properties

##### [nameToInstanceCount](../package-fuchsia_inspect_inspect/Inspect/nameToInstanceCount.md) &#8596; Map&lt;String, int>



Maps an inspect instance name to the number of instantiations
of that inspector. Used to deduplicate requests for
similarly named inspectors.
