Method Summary

Modifier and Type	Method and Description
DataType	getDataType() Gets the DataType that is represented by the given T.
T	read(ByteBuf buffer, GraphBinaryReader context) Reads the type information and value from the buffer and returns an instance of T.
T	readValue(ByteBuf buffer, GraphBinaryReader context, boolean nullable) Reads the value from the buffer (not the type information) and returns an instance of T.
ByteBuf	write(T value, ByteBufAllocator allocator, GraphBinaryWriter context) Writes the type code, information and value to a buffer using the provided allocator.
abstract ByteBuf	writeValue(T value, ByteBufAllocator allocator, GraphBinaryWriter context) Writes a non-nullable value into a buffer using the provided allocator.
ByteBuf	writeValue(T value, ByteBufAllocator allocator, GraphBinaryWriter context, boolean nullable) Writes the value to a buffer, composed by the value flag and the sequence of bytes.

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(ByteBuf buffer,
              GraphBinaryReader context)
       throws SerializationException

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:

SerializationException

readValue

public T readValue(ByteBuf buffer,
                   GraphBinaryReader context,
                   boolean nullable)
            throws SerializationException

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:

SerializationException

write

public ByteBuf write(T value,
                     ByteBufAllocator allocator,
                     GraphBinaryWriter context)
              throws SerializationException

Description copied from interface: TypeSerializer

Writes the type code, information and value to a buffer using the provided allocator.

Specified by:

write in interface TypeSerializer<T>

Throws:

SerializationException

writeValue

public ByteBuf writeValue(T value,
                          ByteBufAllocator allocator,
                          GraphBinaryWriter context,
                          boolean nullable)
                   throws SerializationException

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:

SerializationException

writeValue

public abstract ByteBuf writeValue(T value,
                                   ByteBufAllocator allocator,
                                   GraphBinaryWriter context)
                            throws SerializationException

Writes a non-nullable value into a buffer using the provided allocator.

Parameters:

value - A non-nullable value.

allocator - The buffer allocator to use.

context - The binary writer.

Throws:

SerializationException
