    File targetFile = new File(targetFolder, path);
    generatedFiles.add(targetFile);
    try (Writer w = writerFor(targetFile)) {

Example 2 with ScalaWriter

use of com.querydsl.codegen.utils.ScalaWriter in project querydsl by querydsl.

private void write(Serializer serializer, File targetFile, EntityType type) throws IOException {
    if (!classes.add(targetFile.getPath())) {
        throw new IllegalStateException("Attempted to write multiple times to " + targetFile.getPath() + ", please check your configuration");
    }
    StringWriter w = new StringWriter();
    CodeWriter writer = createScalaSources ? new ScalaWriter(w) : new JavaWriter(w);
    serializer.serialize(type, SimpleSerializerConfig.DEFAULT, writer);
    // conditional creation
    boolean generate = true;
    byte[] bytes = w.toString().getBytes(sourceEncoding);
    if (targetFile.exists() && targetFile.length() == bytes.length) {
        String str = new String(Files.readAllBytes(targetFile.toPath()), Charset.forName(sourceEncoding));
        if (str.equals(w.toString())) {
            generate = false;
        }
    } else {
        targetFile.getParentFile().mkdirs();
    }
    if (generate) {
        Files.write(targetFile.toPath(), bytes);
    }
}
