Interface DynAny

All Superinterfaces:

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.

Method Detail

type

public TypeCode type()

Returns the TypeCode of the object inserted into this DynAny.

Returns:

the TypeCode object.

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.
