Class DynUnionHolder

java.lang.Object
org.omg.DynamicAny.DynUnionHolder
All Implemented Interfaces:
Streamable

public final class DynUnionHolder extends Object implements Streamable
DynUnion objects support the manipulation of IDL unions. A union can have only two valid current positions:
  • zero, which denotes the discriminator
  • one, which denotes the active member
The component_count value for a union depends on the current discriminator: it is 2 for a union whose discriminator indicates a named member, and 1 otherwise.
