AbstractSchema

public AbstractSchema()

方法详细资料

decode

public abstract T decode(io.netty.buffer.ByteBuf byteBuf)

Decode a byteBuf into an object using the schema definition and deserializer implementation

Do not modify reader/writer index of ByteBuf so, it can be reused to access correct data.

参数:

byteBuf - the byte buffer to decode

返回:

the deserialized object

decode

public T decode(io.netty.buffer.ByteBuf byteBuf,
 byte[] schemaVersion)

Decode a byteBuf into an object using a given version.

参数:

byteBuf - the byte array to decode

schemaVersion - the schema version to decode the object. null indicates using latest version.

返回:

the deserialized object

clone

public Schema<T> clone()

指定者:

clone 在接口中 Schema<T>

覆盖:

clone 在类中 Object

atSchemaVersion

public Schema<?> atSchemaVersion(byte[] schemaVersion)
                          throws SchemaSerializationException

Return an instance of this schema at the given version.

参数:

schemaVersion - the version

返回:

the schema at that specific version

抛出:

SchemaSerializationException - in case of unknown schema version

NullPointerException - in case of null schemaVersion and supportSchemaVersioning is true
