Class Nexus\Mcp\Core\Schema\ClientCapabilities

`final`
`readonly`
`implements`	`Arrayable<array{elicitation?: ElicitationCapability, experimental?: ExperimentalCapability, roots?: RootsCapability, sampling?: SamplingCapability, tasks?: ClientTasksCapability}>`

Capabilities a client may support. Known capabilities are defined here, in this schema, but this is not a closed set: any client can define its own, additional capabilities.

`public static`	`fromArray(array<string, mixed> $data): static` Create an instance of the class from an array. Create an instance of the class from an array. Implements `Nexus\Mcp\Core\Schema\Arrayable::fromArray()`	#
`public`	`toArray(): array` Convert the instance to an array. Convert the instance to an array. Implements `Nexus\Mcp\Core\Schema\Arrayable::toArray()`	#
`public`	`jsonSerialize(): array\|stdClass` Implementations substitute `\stdClass` for the empty-object case so `json_encode` emits `{}` rather than `[]`.
