extractStreamId

public static Optional<String> extractStreamId(String filter)

Extracts the last stream id from the filter string passed as part of the elasticsearch query. This is used later to pass to possibly existing message decorators for stream-specific configurations. The assumption is that usually (when listing/searching messages for a stream) only a single stream filter is passed. When this is not the case, only the last stream id will be taked into account. This is currently a workaround. A better solution would be to pass the stream id which is supposed to be the scope for a search query as a separate parameter.

Parameters:

filter - the filter string like "streams:xxxyyyzzz"

Returns:

the optional stream id
