Passing additional meta-data

Assets are represented by strings. Yet, if you need to pass more complex objects, you can add metadata to your value using the meta key.

{
    "some_asset_type": [
        {
            "value": "some_value",
            "metadata": {
                "some": "metadata",
                "more": "metadata"
            }
        }
    ]
}

Notice in this example that the value passed is no longer a string, it is an object containing the value key (that contains the actual value) and the meta key (that contains the metadata).

Metadata can be queried using the getAssets() method that will return complete Asset objects:

$assetType = TheCodingMachine\Discovery::getInstance()->getAssetType('some_asset_type');

foreach ($assetType->getAssets() as $asset) {
    $value = $asset->getValue();
    $meta = $asset->getMetadata();
    $package = $asset->getPackage(); // The composer package this asset comes from
    $packageDir = $asset->getPackageDir(); // The directory of the package
    $priority = $asset->getPriority(); // The priority (if configured, see below)
}
