Class DataContext

  • All Implemented Interfaces:
    java.util.Map<java.lang.String,​java.lang.Object>

    public class DataContext
    extends java.lang.Object
    implements java.util.Map<java.lang.String,​java.lang.Object>
    The DataContext represents a pluggable mechanism for resolving a operation arguments at evaluation time. DataContext use HashMap and expression (Operation argument expression) is used has key. get(Object) Resolve the specified argument expression, and return the corresponding object, if any; otherwise, return null. For example operation argument contains expression like user.profile.id or ${user.profile.id} and data context provide will used to retrieve the value user.profile.id
