Basic Examples  (2)

Serialize an expression:

Wolfram Language code: bin = BinarySerialize[{1, 2, 3}]

Deserialize it:

Wolfram Language code: BinaryDeserialize[bin]

Serialize a graphic:

Wolfram Language code: BinarySerialize[Plot[Sin[x], {x, 0, Pi}]]

Convert the byte array back to an expression:

Wolfram Language code: BinaryDeserialize[%]

Scope  (3)

Serialize a general expression:

Wolfram Language code: bin = BinarySerialize[Solve[α x + β y == γ && β x - y == η, {x, y}]]

Deserialize it:

Wolfram Language code: BinaryDeserialize[bin]

Serialize an unevaluated expression:

Wolfram Language code: bin = BinarySerialize[Unevaluated[1 + 1]]

Deserialize it and keep it held:

Wolfram Language code: BinaryDeserialize[bin, Hold]

Receive a serialized expression from an unknown source:

Wolfram Language code: data = ByteArray["NzpmAXMOQmlnQmFkRnVuY3Rpb25TCmVyYXNlIGRpc2s="]

Wrap the result in HoldComplete to prevent unexpected evaluation:

Wolfram Language code: BinaryDeserialize[data, HoldComplete]

Properties & Relations  (1)

Serialized data from files should be read in using binary-mode functions such as BinaryReadList:

Wolfram Language code: data = ReadByteArray["ExampleData/atoms.wxf"]
Wolfram Language code: BinaryDeserialize[%]
