## org.omg.CORBA
Interface DynAny

All Superinterfaces:
  Object

All Known Subinterfaces:
  DynArray, DynEnum, DynFixed, DynSequence, DynStruct, DynUnion, DynValue

public interface DynAny
extends Object

Enables `org.omg.CORBA.Any` values to be dynamically interpreted (traversed) and constructed. A `DynAny` object is associated with a data value which may correspond to a copy of the value inserted into an `Any`. The `DynAny` APIs enable traversal of the data value associated with an Any at runtime and extraction of the primitive constituents of the data value.

### next
