Create an array that creates a Single-Object encoded byte array.
Create an array that creates a Single-Object encoded byte array. By specifications the encoded array is obtained concatenating the V1_HEADER, the schema id and the avro-encoded payload.
avro-serialized payload
the schema used to encode the payload
a Single-Object encoded byte array
Retrieves all registered schemas
Retrieves all registered schemas
A Sequence of (ID, Schema)
Extracts the ID from a Schema.
Extracts the ID from a Schema.
a Schema with unknown ID
the ID associated with the input schema
Extracts the Schema from its ID.
Extracts the Schema from its ID.
a Long representing an ID
the Schema associated to the input ID
Checks if all the input Schema elements are already in the cache.
Checks if all the input Schema elements are already in the cache. Then, it performs an insert on the storage for all the elements not found on the cache, and then returns each input schema paired with its ID.
all the Schema that should be registered
a sequence of pairs of the input schemas associated with their IDs

Reloads all the schemas from the previously configured storage.
Reloads all the schemas from the previously configured storage. Throws an exception if the cache wasn't already loaded (the getInstance method must always be used to initialize the cache using the required configuration).

Implementation of CachedAvroSchemaManager that loads all the schemas into the cache at startup and perform all the retrieves onto the cache; an access to the storage is performed only if there is a cache miss.
