# GVariant for Java
This library provides a [GVariant][] parser in pure Java.
## Overview
Instances of `Decoder<T>` 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.
## Installation
### Usage with Maven
<project>
...
<dependencies>
...
<dependency>
<groupId>eu.mulk.jgvariant</groupId>
<artifactId>jgvariant-core</artifactId>
<version>0.1.0</version>
</dependency>
...
</dependencies>
...
</project>
### Usage with Gradle
dependencies {
...
implementation("eu.mulk.jgvariant:jgvariant-core:0.1.0")
...
}
## Example
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));
