Method Detail

overrideUserAgentApp

public void overrideUserAgentApp(String name)

Method to override user-agent app name for the de-serializer. This overrides the previously set value in GlueSchemaRegistryConfiguration.

Parameters:

name - AppName

getSchemaDefinition

public String getSchemaDefinition(@NonNull
                                  @NonNull ByteBuffer buffer)

Fetches the schema definition for the serialized data.

Parameters:

buffer - data for which schema definition is needed as ByteBuffer

Returns:

schema definition

Throws:

GlueSchemaRegistryIncompatibleDataException - when data is incompatible with schema registry

getActualData

public byte[] getActualData(byte[] data)

getSchema

public Schema getSchema(@NonNull
                        @NonNull byte[] data)

getSchemaDefinition

public String getSchemaDefinition(@NonNull
                                  @NonNull byte[] data)

Fetches the schema definition for a the serialized data.

Parameters:

data - data for which schema definition is needed as byte array

Returns:

schema for the passed data

Throws:

GlueSchemaRegistryIncompatibleDataException - when data is incompatible with schema registry

deserialize

public Object deserialize(@NonNull
                          @NonNull AWSDeserializerInput deserializerInput)
                   throws AWSSchemaRegistryException

De-serializes the given data and returns an Object. Accepts encapsulated deserializer input.

Parameters:

deserializerInput - Input data object for deserializer

Returns:

de-serialized object instance

Throws:

AWSSchemaRegistryException - Exception during de-serialization

canDeserialize

public boolean canDeserialize(byte[] data)

Returns if the given data array can be deserialized.

Parameters:

data - byte[] of data.

Returns:

boolean.

close

public void close()

Resource clean up for Closeable. This method internally shuts down the background thread for publishing cloud watch metrics. After this is called, a new instance of this class should be created to enable the metrics publishing feature.
