Class Schema

java.lang.Object

com.google.gdata.model.Schema

public final class Schema
extends Object

An immutable set of metadata. Stores an entire tree of metadata about a service or feed provider in a fast, cached, immutable form, so that runtime use of metadata is very cheap. Schemas can be created by using a MetadataRegistry, which can be created using builder().
