🔧 API Reference

Core Components

🔐 Authentication

The SDK supports authentication via access key and secret:

Credentials credentials = new Credentials("your-access-key-id", "your-access-key-secret");
Translator lara = new Translator(credentials);

Environment Variables (Recommended):

export LARA_ACCESS_KEY_ID="your-access-key-id"
export LARA_ACCESS_KEY_SECRET="your-access-key-secret"

Credentials credentials = new Credentials(
    System.getenv("LARA_ACCESS_KEY_ID"),
    System.getenv("LARA_ACCESS_KEY_SECRET")
);

🌍 Translator

// Create translator with credentials
Translator lara = new Translator(credentials);

Text Translation

// Basic translation
TextResult result = lara.translate("Hello", "en-US", "fr-FR");

// Multiple strings
String[] texts = {"Hello", "World"};
TextResult result = lara.translate(texts, "en-US", "fr-FR");

// TextBlocks (mixed translatable/non-translatable content)
TextBlock[] textBlocks = {
    new TextBlock("Translatable text", true),
    new TextBlock("<br>", false),  // Non-translatable HTML
    new TextBlock("More translatable text", true),
};
TextResult result = lara.translateBlocks(textBlocks, "en-US", "fr-FR");

// With advanced options
TranslateOptions options = new TranslateOptions()
    .setInstructions("Formal tone")
    .setAdaptTo("memory-id")  // Replace with actual memory IDs
    .setGlossaries("glossary-id")  // Replace with actual glossary IDs
    .setStyle(TranslationStyle.FLUID)
    .setTimeoutMs(10000L);

TextResult result = lara.translate("Hello", "en-US", "fr-FR", options);

Quality Estimation

Use qualityEstimation() to score how well a translation matches its source. Pass a single sentence/translation pair to get a single result, or two parallel lists to get one result per pair.

// Single pair
QualityEstimationResult single = lara.qualityEstimation(
    "en-US",
    "it-IT",
    "Hello, how are you today?",
    "Ciao, come stai oggi?"
);
System.out.println(single.getScore()); // e.g. 0.768

// Batch
List<QualityEstimationResult> batch = lara.qualityEstimation(
    "en-US",
    "it-IT",
    Arrays.asList("Good morning.", "The weather is nice."),
    Arrays.asList("Buongiorno.", "Il tempo è bello.")
);
System.out.println(batch.stream().map(QualityEstimationResult::getScore).collect(java.util.stream.Collectors.toList())); // e.g. [0.751, 0.713]

📖 Document Translation

Simple document translation

File inputFile = new File("/path/to/your/document.txt");  // Replace with actual file path
InputStream fileStream = lara.documents.translate(inputFile, "document.txt", "en-US", "fr-FR");

// With options
DocumentTranslateOptions options = new DocumentTranslateOptions()
    .setAdaptTo("memory-id")  // Replace with actual memory IDs
    .setGlossaries("glossary-id")  // Replace with actual glossary IDs
    .setStyle(TranslationStyle.FLUID)
    .setNoTrace(false);

InputStream fileStream = lara.documents.translate(inputFile, "document.txt", "en-US", "fr-FR", options);

Document translation with status monitoring

Document upload

//Optional: upload options
DocumentUploadOptions uploadOptions = new DocumentUploadOptions()
    .setAdaptTo("memory-id")  // Replace with actual memory IDs
    .setGlossaries("glossary-id")  // Replace with actual glossary IDs
    .setNoTrace(false);

Document document = lara.documents.upload(inputFile, "document.txt", "en-US", "fr-FR", uploadOptions);

Document translation status monitoring

String status = lara.documents.status(document.getId());

Download translated document

InputStream fileStream = lara.documents.download(document.getId());

🎵 Audio Translation

Simple audio translation

File inputFile = new File("/path/to/your/audio.mp3");
InputStream audioStream = lara.audio.translate(inputFile, "en-US", "fr-FR");

// With options
AudioUploadOptions options = new AudioUploadOptions()
    .setAdaptTo("memory-id")  // Replace with actual memory IDs
    .setGlossaries("glossary-id")  // Replace with actual glossary IDs
    .setStyle(TranslationStyle.FLUID)
    .setNoTrace(false);

InputStream audioStream = lara.audio.translate(inputFile, "en-US", "fr-FR", options);

Audio translation with status monitoring

Audio upload

AudioUploadOptions uploadOptions = new AudioUploadOptions()
    .setAdaptTo("memory-id")  // Replace with actual memory IDs
    .setGlossaries("glossary-id")  // Replace with actual glossary IDs
    .setNoTrace(false);

Audio audio = lara.audio.upload(inputFile, "en-US", "fr-FR", uploadOptions);

Audio translation status monitoring

Audio status = lara.audio.status(audio.getId());

Download translated audio

InputStream audioStream = lara.audio.download(audio.getId());

🧠 Memory Management

// Create memory
Memory memory = lara.memories.create("MyMemory");

// Create memory with external ID (MyMemory integration)
Memory memory = lara.memories.create("Memory from MyMemory", "aabb1122");  // Replace with actual external ID

// Important: To update/overwrite a translation unit you must provide a tuid. Calls without a tuid always create a new unit and will not update existing entries.
// Add translation to single memory
MemoryImport memoryImport = lara.memories.addTranslation("mem_1A2b3C4d5E6f7G8h9I0jKl", "en-US", "fr-FR", "Hello", "Bonjour", "greeting_001");

// Add translation to multiple memories
List<String> memoryIds = Arrays.asList("mem_1A2b3C4d5E6f7G8h9I0jKl", "mem_2XyZ9AbC8dEf7GhI6jKlMn");  // Replace with actual memory IDs
MemoryImport memoryImport = lara.memories.addTranslation(memoryIds, "en-US", "fr-FR", "Hello", "Bonjour", "greeting_002");

// Add with context
MemoryImport memoryImport = lara.memories.addTranslation(
        "mem_1A2b3C4d5E6f7G8h9I0jKl", "en-US", "fr-FR", "Hello", "Bonjour", "tuid", 
        "sentenceBefore", "sentenceAfter"
);

// TMX import from file
File tmxFile = new File("/path/to/your/memory.tmx");  // Replace with actual TMX file path
MemoryImport memoryImport = lara.memories.importTmx("mem_1A2b3C4d5E6f7G8h9I0jKl", tmxFile);

// Delete translation
// Important: if you omit tuid, all entries that match the provided fields will be removed
MemoryImport deleteJob = lara.memories.deleteTranslation(
        "mem_1A2b3C4d5E6f7G8h9I0jKl", "en-US", "fr-FR", "Hello", "Bonjour", "greeting_001"
);

// Wait for import completion (timeout in MILLISECONDS)
MemoryImport completedImport = lara.memories.waitForImport(memoryImport, 300000L); // 5 minutes

📚 Glossary Management

// Create glossary
Glossary glossary = lara.glossaries.create("MyGlossary");

// Import CSV from file
File csvFile = new File("/path/to/your/glossary.csv");  // Replace with actual CSV file path
GlossaryImport glossaryImport = lara.glossaries.importCsv("gls_1A2b3C4d5E6f7G8h9I0jKl", csvFile);

// Add (or replace) individual terms to glossary
List<Map<String, String>> terms = Arrays.asList(
    Map.of("language", "fr-FR", "value", "Bonjour"),
    Map.of("language", "es-ES", "value", "Hola")
);
Object addResult = lara.glossaries.addOrReplaceEntry("gls_1A2b3C4d5E6f7G8h9I0jKl", terms, null);

// Remove a specific term from glossary
Map<String, String> termToRemove = Map.of("language", "fr-FR", "value", "Bonjour");
Object removeResult = lara.glossaries.deleteEntry("gls_1A2b3C4d5E6f7G8h9I0jKl", termToRemove, null);

// Check import status
GlossaryImport importStatus = lara.glossaries.getImportStatus("gls_1A2b3C4d5E6f7G8h9I0jKl");

// Wait for import completion
GlossaryImport completedImport = lara.glossaries.waitForImport(glossaryImport, 300000L); // 5 minutes

// Export glossary
String csvData = lara.glossaries.export("gls_1A2b3C4d5E6f7G8h9I0jKl", Glossary.Type.CSV_TABLE_UNI, "en-US");

// Get glossary terms count
GlossaryCounts counts = lara.glossaries.counts("gls_1A2b3C4d5E6f7G8h9I0jKl");

🎨 Styleguides

Styleguides let you apply custom translation style rules. They can be listed and retrieved through the SDK.

// List all styleguides
List<Styleguide> styleguides = lara.styleguides.list();

// Get a specific styleguide by ID
Styleguide styleguide = lara.styleguides.get("stg_1A2b3C4d5E6f7G8h9I0jKl");

Translate with a styleguide

TranslateOptions options = new TranslateOptions()
    .setStyleguideId("stg_1A2b3C4d5E6f7G8h9I0jKl");  // Replace with actual styleguide ID

TextResult result = lara.translate("Hello, world!", "en-US", "it-IT", options);

Styleguide reasoning

Enable reasoning to see what the styleguide changed and why:

TranslateOptions options = new TranslateOptions()
    .setStyleguideId("stg_1A2b3C4d5E6f7G8h9I0jKl")
    .setStyleguideReasoning(true)
    .setStyleguideExplanationLanguage("en-US");

TextResult result = lara.translate("Hello, world!", "en-US", "it-IT", options);

StyleguideResults sgResults = result.getStyleguideResults();
if (sgResults != null) {
    System.out.println("Original translation: " + sgResults.getOriginalTranslation());

    for (StyleguideChange change : sgResults.getChanges()) {
        System.out.println("Before: " + change.getOriginalTranslation());
        System.out.println("After:  " + change.getRefinedTranslation());
        System.out.println("Why:    " + change.getExplanation());
    }
}

Translation Options

public class TranslateOptions {
    setAdaptTo(String... memoryIds)             // Memory IDs to adapt to
    setGlossaries(String... glossaryIds)        // Glossary IDs to use
    setInstructions(String... instructions)     // Translation instructions
    setStyle(TranslationStyle style)            // Translation style (FLUID, FAITHFUL, CREATIVE)
    setContentType(String contentType)          // Content type (text/plain, text/html, etc.)
    setMultiline(Boolean multiline)             // Enable multiline translation
    setTimeoutMs(Long timeoutMs)                // Request timeout in milliseconds
    setSourceHint(String sourceHint)            // Hint for source language detection
    setNoTrace(Boolean noTrace)                 // Disable request tracing
    setVerbose(Boolean verbose)                 // Enable verbose response
    setStyleguideId(String id)                  // Styleguide ID to apply
    setStyleguideReasoning(boolean enabled)     // Enable styleguide change reasoning
    setStyleguideExplanationLanguage(String lang) // Language for change explanations
}

Language Codes

The SDK supports full language codes (e.g., en-US, fr-FR, es-ES) as well as simple codes (e.g., en, fr, es):

// Full language codes (recommended)
TextResult result = lara.translate("Hello", "en-US", "fr-FR");

// Simple language codes
TextResult result = lara.translate("Hello", "en", "fr");

🌐 Supported Languages

The SDK supports all languages available in the Lara API. Use the getLanguages() method to get the current list:

List<String> languages = lara.getLanguages();
System.out.println("Supported languages: " + String.join(", ", languages));

⚙️ Configuration

Error Handling

The SDK provides detailed error information:

try {
    TextResult result = lara.translate("Hello", "en-US", "fr-FR");
    System.out.println("Translation: " + result.getTranslation());
} catch (LaraApiException e) {
    System.err.println("API Error [" + e.getStatusCode() + "]: " + e.getMessage());
    System.err.println("Error type: " + e.getType());
} catch (LaraException e) {
    System.err.println("SDK Error: " + e.getMessage());
}
