use of io.plaidapp.data.api.designernews.StoryWeigher in project plaid by nickbutcher.

the class FeedAdapter method weighItems.

/**
     * Calculate a 'weight' [0, 1] for each data type for sorting. Each data type/source has a
     * different metric for weighing it e.g. Dribbble uses likes etc. but some sources should keep
     * the order returned by the API. Weights are 'scoped' to the page they belong to and lower
     * weights are sorted earlier in the grid (i.e. in ascending weight).
