#use_extension(module_obj, &condition) ⇒ Object

Register an extension module with the class. A block taking one parameter can be supplied; the block will be passed an instance of a Document, and the extension will be applied only if the block evaluates as true. If no condition is given, the extension will be applied to every instance of the class.

SolrDocument.use_extension( SomeExtensionModule ) { | document | should_apply_some_extension?(document) } SolrDocument.use_extension( SomeExtensionModule) # will be applied to all docs
