Method Detail

scanUnsafe

@Nullable
public Object scanUnsafe(Scannable.Attr key)

Description copied from interface: Scannable

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 Scannable.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 Scannable.scan(Attr), which will return a typed value and fall back to the key's default if the component didn't define any mapping.

Specified by:

scanUnsafe in interface Scannable

Parameters:

key - a Scannable.Attr to resolve for the component.

Returns:

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