Class: Selenium::WebDriver::BiDi::Protocol::Input::WheelSourceAction Private

Outbound mirror of from_json: build the variant the command's kwargs describe so its typed as_json drives null-vs-absent per field (a flat hash through ::Selenium::WebDriver::BiDi::Transport cannot).

values maps each variant's discriminator symbol to its wire token, so an inbound payload tag (a wire string) can be matched to the symbol-keyed table.

A non-Hash payload is a bare scalar arm (e.g.

Declared (via the schema's objectOnly signal) on a union whose every arm is an object, so a non-Hash payload is a schema violation rather than a scalar arm.

Declared (via the schema's scalarValues signal) on a non-object_only union whose bare-scalar arms are a fixed set of literals (input.Origin's "viewport" / "pointer").

Outbound mirror of from_json: is value one this union accepts? Any variant is accepted, and a variant that is itself a union recurses (e.g. LocalValue's RemoteReference fallback).

An explicit nil kwarg still counts as supplied; a non-nullable field set to nil is rejected at construction (Data.new), not here.

The wire tag mapped back to its variant symbol (the table's key); an unrecognized tag falls through as-is so select misses and from_json raises.

A bare-scalar arm must be one of the literals the schema pinned for this union (scalar_values, e.g. input.Origin's "viewport" / "pointer").

The discriminator value may legitimately be null (e.g.

A variant that is itself a union recurses; a record variant is matched by instance.

The matching variant's ref, or nil when none matches (the fallback if declared).

Every variant's class name: the discriminated table, the presence paths, and the fallback.
