public Optional<? extends DiscoverySelector> parse(DiscoverySelectorIdentifier identifier, DiscoverySelectorIdentifierParser.Context context) Parse the supplied `DiscoverySelectorIdentifier`. The JUnit Platform will only invoke this method if the supplied `DiscoverySelectorIdentifier` has a prefix that matches the value returned by `getPrefix()`.

public Optional<? extends DiscoverySelector> parse(DiscoverySelectorIdentifier identifier, DiscoverySelectorIdentifierParser.Context context)

Parse the supplied DiscoverySelectorIdentifier.

The JUnit Platform will only invoke this method if the supplied DiscoverySelectorIdentifier has a prefix that matches the value returned by getPrefix().

Parameters

identifier:DiscoverySelectorIdentifier: the DiscoverySelectorIdentifier to parse
context:DiscoverySelectorIdentifierParser.Context: the Context to use for parsing

Returns:Optional<? extends DiscoverySelector>

an Optional containing the parsed DiscoverySelector; never null but potentially empty
