Class JsonUtils

java.lang.Object

co.ankatech.ankasecure.sdk.internal.util.JsonUtils

public final class JsonUtils
extends Object

Thread-safe JSON helper with a single, shared ObjectMapper.

The mapper is tuned for human-readable output:

• Pretty printed (two-space indentation).
• ISO-8601 date/time serialisation via JavaTimeModule.
• Timestamps disabled – epoch millis are never written.
• null exclusion – properties with a null value are silently omitted from the JSON payload to keep the output succinct and to avoid confusion on the consumer side.

Since:

2.1.0
