Examples of FastBlobSchema

com.netflix.zeno.fastblob.record.schema.FastBlobSchema
A schema for a record contained in a FastBlob.
The fields each have a position, which is the order in which they will appear in a FastBlob serialized representation.
The schema is a hash table of Strings (field name) to field position.
Schemas are flat lists of fields, each specified by (fieldName, fieldType, objectType). objectType will be null for primitive types. @author dkoszewnik
