Class AnyUtil

java.lang.Object
  org.eclipse.smila.datamodel.util.AnyUtil

public final class AnyUtil
extends java.lang.Object

utility class for handling / conversion of Any objects. Hint: The Any-to-JSON conversion for Date(Time)s is not symmetric. If the Any object contains Date(Time) values, they will be serialized to String values in simple timestamp format. But when parsing JSON to an Any object, Date(Time) strings will not be recognized anymore, but just read as String values.

Immutable empty AnyMap instance.

Method Detail

anyToNative

public static java.lang.Object anyToNative(Any any)

Converts an Any object into a native java object.

Parameters:

any - the Any object

Returns:

a Pojo

objectToAny

public static Any objectToAny(java.lang.Object object)

Converts an object to an Any (recursively). The leaf object(s) must be convertable by DataFactory.autoConvertValue(Object).

Parameters:

object - The object to be converted. Supported (and tested in this order) are

• Map<String, Object>
• Collections<Object>
• Object[]
• Any other object that can be DataFactory.autoConvertValue(Object)

Returns:

The converted Any

saveGet

public static Any saveGet(Any any,
                          java.lang.String[] path)

any - the Any object.

path - path to the entry.

Returns:

value associated to the path.
