README: Add module overview. Change-Id: I8c4701e8d4561940025165dd3beb448e3443de36
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));
