org.locationtech.geogig.storage.text.TextSerializationFactory

An {@link ObjectSerialisingFactory} for the {@link RevObject}s text format.

The following formats are used to interchange {@link RevObject} instances in a text format:

Commit:

 {@code COMMIT\n}{@code "tree" + "\t" +   + "\n"}{@code "parents" + "\t" +   [+ " " + ...]  + "\n"}{@code "author" + "\t" +    + " " +   + "\t" +  + "\t" +  + "\n"}{@code "committer" + "\t" +    + " " +   + "\t" +  + "\t" +  + "\n"}     * {@code "message" + "\t" +   + "\n"}

Tree:

 {@code TREE\n} {@code "size" + "\t" +   + "\n"}{@code "numtrees" + "\t" +   + "\n"}{@code "BUCKET" + "\t" +   + "\t" +  + "\t" +  + "\n"}or  {@code "REF" + "\t" +   + "\t" +  + "\t" +  + "\t" +  + "\t" + "\n"}. . .

Feature:

 {@code FEATURE\n}{@code "" + "\t" +   + "\n"}. . .      {@code "" + "\t" +   + "\n"}For array types, values are written as a space-separated list of single values, enclosed between square brackets

FeatureType:

 {@code FEATURE_TYPE\n} {@code "name" + "\t" +   + "\n"}{@code "" + "\t" +   + "\t" +  + "\t" +  +  "\t" + > + "\n"}{@code "" + "\t" +   + "\t" +  + "\t" +  +  "\t" + > + "\n"}. . .

Tag:

 {@code "id" + "\t" +   + "\n"}...

        }
        ObjectId id = ObjectId.valueOf(lines.get(0).split("\t")[1].trim());
        String commitString = Joiner.on("\n").join(lines.subList(1, lines.size()));
        ByteArrayInputStream stream = new ByteArrayInputStream(
                commitString.getBytes(Charsets.UTF_8));
        ObjectReader<RevCommit> reader = new TextSerializationFactory().createCommitReader();
        RevCommit revCommit = reader.read(id, stream);
        return revCommit;
