org.omg.CORBA
Interface DynAny

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

public interface DynAny
extends Object

org.omg.CORBA.Any values can be dynamically interpreted (traversed) and constructed through DynAny objects. 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.

public void assign(DynAny dyn_any)
            throws Invalid
Copy the contents from one Dynamic Any into another.
Parameters:
dyn_any - the DynAny object whose contents are assigned to this DynAny.
Throws:
Invalid - if the source DynAny is invalid

public void from_any(Any value)
              throws Invalid
Make a DynAny object from an Any object.
Parameters:
value - the Any object.
