Interface JsonUtil

All Known Implementing Classes:

JsonUtilImpl

public interface JsonUtil

Utility methods for getting JSON content loaded from the filesystem, the classpath, or in memory Strings. Also has methods to serialize Java object to JSON strings. Implementations of this interface can specify their own Jackson ObjectMapper so that Domain specific Java Objects can successfully be serialized and de-serialized.
