Description

Allows a user to register a custom Indexing function for a specific type.

When you have special properties you would like to index for an asset or a Unity Object, Unity suggests Writing a custom indexer routine . The newly indexed words or properties will allow the user to search for them using the Search Query Language. The registered function must be of type: static void MyCustomIndexer(CustomObjectIndexerTarget context, ObjectIndexer indexer);

See ObjectIndexer for the various methods you can invoke on indexer.

The CustomObjectIndexerTarget context argument can be used to access additional information about what is about to be indexed.

[CustomObjectIndexer(typeof(Material))]
internal static void MaterialShaderReferences(CustomObjectIndexerTarget context, ObjectIndexer indexer)
{
   var material = context.target as Material;
   if (material == null)
       return;

if (material.shader) { var fullShaderName = material.shader.name.ToLowerInvariant(); var shortShaderName = System.IO.Path.GetFileNameWithoutExtension(fullShaderName); indexer.AddProperty("ref", shortShaderName, context.documentIndex); indexer.AddProperty("ref", fullShaderName, context.documentIndex); } }
