# Gradle platform architecture

Gradle is arranged into coarse-grained components called "architecture modules" and "platforms".
See [ADR4](standards/0004-use-a-platform-architecture.md) for a definition of these terms.

The diagram below shows the current set of architecture modules and platforms:

            return username;
        }

        // Show first and last character only
        if (username.length() <= 2) {
            return "***";
        }

        return username.charAt(0) + "***" + username.charAt(username.length() - 1);
    }

    private String maskIpAddress(String ip) {
        if (!maskSensitiveData || ip == null) {
            return ip;
        }

      Response
        .Builder()
        .request(request)
        .protocol(Protocol.HTTP_1_1)
        .code(200)
        .message("Intercepted!")
        .body("abc".toResponseBody("text/plain; charset=utf-8".toMediaType()))
        .build()
    client =
      client
        .newBuilder()
        .addInterceptor(Interceptor { chain: Interceptor.Chain? -> interceptorResponse })
        .build()

});
```

### Text Processing and JSON
```java
import org.codelibs.core.text.*;

// JSON utilities with proper escaping
String escaped = JsonUtil.escape("Hello \"World\" with special chars");
String unescaped = JsonUtil.unescape(escaped);

// Text tokenization
Tokenizer tokenizer = new Tokenizer("field1,field2,field3", ",");
while (tokenizer.hasMoreTokens()) {
    String token = tokenizer.nextToken();

                int lastIndex = expr.indexOf('}', index);
                if (lastIndex >= 0) {
                    String retVal = expr.substring(0, index);

                    if ((index > 0) && (expr.charAt(index - 1) == '$')) {
                        retVal += expr.substring(index + 1, lastIndex + 1);
                    } else {
                        Object subResult = evaluate(expr.substring(index, lastIndex + 1));

Nevertheless, we can declare the expected schema for the request body.
