Interface JsonEventObject

All Superinterfaces:

java.util.Map<java.lang.String,java.lang.Object>

public interface JsonEventObject
extends java.util.Map<java.lang.String,java.lang.Object>

All JSON underlying event objects implement this interface.

In general, byte code does not use the Map methods and instead uses the implementation class fields directly.

This is a read-only implementation of the Map interface.

All predefined properties as well as all dynamic properties become available through the Map interface.
