    All Methods Instance Methods Abstract Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `DataType` | `getDataType()` Gets the `DataType` that is represented by the given `T`.
    `T` | `read(Buffer buffer, GraphBinaryReader context)` Reads the type information and value from the buffer and returns an instance of T.
    `protected abstract T` | `readValue(Buffer buffer, GraphBinaryReader context)` Reads a non-nullable value according to the type format.
    `T` | `readValue(Buffer buffer, GraphBinaryReader context, boolean nullable)` Reads the value from the buffer (not the type information) and returns an instance of T.
    `void` | `write(T value, Buffer buffer, GraphBinaryWriter context)` Writes the type code, information and value to a buffer using the provided allocator.
    `protected abstract void` | `writeValue(T value, Buffer buffer, GraphBinaryWriter context)` Writes a non-nullable value into a buffer using the provided allocator.
    `void` | `writeValue(T value, Buffer buffer, GraphBinaryWriter context, boolean nullable)` Writes the value to a buffer, composed by the value flag and the sequence of bytes.

    - #### SimpleTypeSerializer

          public SimpleTypeSerializer(DataType dataType)

  - ### Method Detail

    - #### getDataType

          public DataType getDataType()

      Description copied from interface: `TypeSerializer`
      Gets the `DataType` that is represented by the given `T`.
      Specified by:
        `getDataType` in interface `TypeSerializer<T>`

    - #### read

          public T read(Buffer buffer,
                        GraphBinaryReader context)
                 throws IOException

      Description copied from interface: `TypeSerializer`
      Reads the type information and value from the buffer and returns an instance of T.
      Specified by:
        `read` in interface `TypeSerializer<T>`
      Throws:
        `IOException`

    - #### readValue

          public T readValue(Buffer buffer,
                             GraphBinaryReader context,
                             boolean nullable)
                      throws IOException

      Description copied from interface: `TypeSerializer`
      Reads the value from the buffer (not the type information) and returns an instance of T.

      Implementors should throw an exception when a complex type doesn't support reading without the type information.

      Specified by:
        `readValue` in interface `TypeSerializer<T>`
      Throws:
        `IOException`

    - #### readValue

          protected abstract T readValue(Buffer buffer,
                                         GraphBinaryReader context)
                                  throws IOException

      Reads a non-nullable value according to the type format.
      Parameters:
        `buffer` - A buffer which reader index has been set to the beginning of the {value}.
        `context` - The binary reader.
      Returns:
      Throws:
        `IOException`

    - #### write

                     throws IOException

      Description copied from interface: `TypeSerializer`
      Writes the type code, information and value to a buffer using the provided allocator.

                                 boolean nullable)
                          throws IOException

      Description copied from interface: `TypeSerializer`
      Writes the value to a buffer, composed by the value flag and the sequence of bytes.
      Specified by:
        `writeValue` in interface `TypeSerializer<T>`
      Throws:
        `IOException`

    - #### writeValue

                                             GraphBinaryWriter context)
                                      throws IOException

      Writes a non-nullable value into a buffer using the provided allocator.
      Parameters:
        `value` - A non-nullable value.
