scanUnsafeback to summary
public Object scanUnsafe(Scannable.Attr<T> key)

Implements reactor.core.Scannable.scanUnsafe.

Doc from reactor.core.Scannable.scanUnsafe.

This method is used internally by components to define their key-value mappings in a single place. Although it is ignoring the generic type of the Attr key, implementors should take care to return values of the correct type, and return null if no specific value is available.

For public consumption of attributes, prefer using scan(Attr), which will return a typed value and fall back to the key's default if the component didn't define any mapping.

Parameters
key:Scannable.Attr<T>

a Attr to resolve for the component.

Returns:Object

the value associated to the key for that specific component, or null if none.

Parameters
