All Implemented Interfaces:
SchemaAware
Enclosing class:
StdArraySerializers

public static final class StdArraySerializers.ByteArraySerializer
extends StdSerializer<byte[]>

Unlike other integral number array serializers, we do not just print out byte values as numbers. Instead, we assume that it would make more sense to output content as base64 encoded bytes (using default base64 encoding).

NOTE: since it is NOT serialized as an array, can not use AsArraySerializer as base

Constructor Detail

StdArraySerializers.ByteArraySerializer

public StdArraySerializers.ByteArraySerializer()
Method Detail

isEmpty

public boolean isEmpty(byte[] value)
Description copied from class: JsonSerializer
Method called to check whether given serializable value is considered "empty" value (for purposes of suppressing serialization of empty values).

Default implementation will consider only null values to be empty.

Overrides:
isEmpty in class JsonSerializer<byte[]>

serialize

public void serialize(byte[] value,
                      com.fasterxml.jackson.core.JsonGenerator jgen,
                      SerializerProvider provider)
               throws IOException,
                      com.fasterxml.jackson.core.JsonGenerationException
Description copied from class: JsonSerializer
Method that can be called to ask implementation to serialize values of type this serializer handles.

Specified by:
serialize in class StdSerializer<byte[]>
Parameters:
value - Value to serialize; can not be null.
jgen - Generator used to output resulting Json content
provider - Provider that can be used to get serializers for serializing Objects value contains, if any.
Throws:
IOException
com.fasterxml.jackson.core.JsonGenerationException

serializeWithType

public void serializeWithType(byte[] value,
                              com.fasterxml.jackson.core.JsonGenerator jgen,
                              SerializerProvider provider,
                              TypeSerializer typeSer)
                       throws IOException,
                              com.fasterxml.jackson.core.JsonGenerationException
Description copied from class: JsonSerializer
Method that can be called to ask implementation to serialize values of type this serializer handles, using specified type serializer for embedding necessary type information.

Default implementation will throw UnsupportedOperationException to indicate that proper type handling needs to be implemented.

For simple datatypes written as a single scalar value (JSON String, Number, Boolean), implementation would look like:

  // note: method to call depends on whether this type is serialized as JSON scalar, object or Array!
  typeSer.writeTypePrefixForScalar(value, jgen);
  serialize(value, jgen, provider);
  typeSer.writeTypeSuffixForScalar(value, jgen);
and implementations for type serialized as JSON Arrays or Objects would differ slightly, as START-ARRAY>/END-ARRAY and START-OBJECT>/END-OBJECT pairs need to be properly handled with respect to serializing of contents.

Overrides:
serializeWithType in class JsonSerializer<byte[]>
Parameters:
value - Value to serialize; can not be null.
jgen - Generator used to output resulting Json content
provider - Provider that can be used to get serializers for serializing Objects value contains, if any.
typeSer - Type serializer to use for including type information
Throws:
IOException
com.fasterxml.jackson.core.JsonGenerationException

getSchema

public JsonNode getSchema(SerializerProvider provider,
                          Type typeHint)
Description copied from class: StdSerializer
Default implementation simply claims type is "string"; usually overriden by custom serializers.

Specified by:
getSchema in interface SchemaAware
Overrides:
getSchema in class StdSerializer<byte[]>
Parameters:
provider - The serializer provider.
typeHint - A hint about the type.
Returns:
Json-schema for this serializer.
