    • 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 org.apache.pulsar.client.api.Schema<T> clone()
      指定者:
      clone 在接口中 org.apache.pulsar.client.api.Schema<T>
      覆盖:
      clone 在类中 Object

    • atSchemaVersion

      public org.apache.pulsar.client.api.Schema<?> atSchemaVersion(byte[] schemaVersion) throws org.apache.pulsar.client.api.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:
      org.apache.pulsar.client.api.SchemaSerializationException - in case of unknown schema version
      NullPointerException - in case of null schemaVersion and supportSchemaVersioning is true
