jgvariant-ostree: DeltaPartPayload: Decompress LZMA if needed. Change-Id: I4a751b7778c30d2e126a058c766edaef7b641415
This library provides a GVariant parser in pure Java.
jgvariant-core provides Decoder<T>, which read a given type of GVariant-encoded value from a ByteBuffer. The class also contains factory methods to acquire those instances.
The various subclasses of Decoder together implement the GVariant serialization specification.
jgvariant-ostree provides instances of Decoder<T> for various GVariant types used in OSTree repositories.
To parse a GVariant value of type "a(si)", which is an array of pairs of String and int, you can use the following code:
record ExampleRecord(String s, int i) {}
var decoder =
Decoder.ofArray(
Decoder.ofStructure(
ExampleRecord.class,
Decoder.ofString(StandardCharsets.UTF_8),
Decoder.ofInt().withByteOrder(ByteOrder.LITTLE_ENDIAN)));
byte[] bytes = ...;
List<ExampleRecord> example = decoder.decode(ByteBuffer.wrap(bytes));
