StringSerializer

public StringSerializer()

Constructs a new StringSerializer.

Method Details

deserialize

public String deserialize(io.netty.buffer.ByteBuf in,
 NodeStore store)

Description copied from interface: BabelNetworkSerializer

Reads an instance of T from the supplied buffer. The buffer's reader index must be positioned at the first byte of the encoded object. Upon return the reader index is advanced past all bytes consumed.

Specified by:

deserialize in interface BabelNetworkSerializer<String>

Parameters:

in - the source buffer

store - the node store context for resolving node components

Returns:

the deserialized object

serialize

public void serialize(String object,
 io.netty.buffer.ByteBuf out,
 NodeStore store)

Description copied from interface: BabelNetworkSerializer

Encodes object and appends the resulting bytes to out.

Specified by:

serialize in interface BabelNetworkSerializer<String>

Parameters:

object - the object to serialize

out - the destination buffer

store - the node store context for resolving node components

getObjectClass

public Class<String> getObjectClass()

Description copied from interface: BabelNetworkSerializer

Returns the class of objects handled by this serializer, used for registry lookup.

Specified by:

getObjectClass in interface BabelNetworkSerializer<String>

Returns:

the handled class

getEstimateSize

public int getEstimateSize(String object)

Description copied from interface: BabelNetworkSerializer

Returns an estimated size in bytes for the given object.

Specified by:

getEstimateSize in interface BabelNetworkSerializer<String>

Parameters:

object - the object to estimate

Returns:

estimated byte size, or 0 if unknown
