public class _DynUnionStub extends ObjectImpl implements DynUnion
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.

    • get_discriminator

      public DynAny get_discriminator()
      Returns the current discriminator value.
      Specified by:
      get_discriminator in interface DynUnionOperations

    • set_discriminator

      public void set_discriminator(DynAny d) throws TypeMismatch
      Sets the discriminator of the DynUnion to the specified value. Setting the discriminator to a value that is consistent with the currently active union member does not affect the currently active member. Setting the discriminator to a value that is inconsistent with the currently active member deactivates the member and activates the member that is consistent with the new discriminator value (if there is a member for that value) by initializing the member to its default value. Setting the discriminator of a union sets the current position to 0 if the discriminator value indicates a non-existent union member (has_no_active_member returns true in this case). Otherwise, if the discriminator value indicates a named union member, the current position is set to 1 (has_no_active_member returns false and component_count returns 2 in this case).
      Specified by:
      set_discriminator in interface DynUnionOperations
      Throws:
      TypeMismatch - if the TypeCode of the parameter is not equivalent to the TypeCode of the union's discriminator
      TypeMismatch

    • set_to_default_member

      public void set_to_default_member() throws TypeMismatch
      Sets the discriminator to a value that is consistent with the value of the default case of a union. It sets the current position to zero and causes component_count to return 2.
      Specified by:
      set_to_default_member in interface DynUnionOperations
      Throws:
      TypeMismatch - if the union does not have an explicit default case
      TypeMismatch

    • set_to_no_active_member

      public void set_to_no_active_member() throws TypeMismatch
      Sets the discriminator to a value that does not correspond to any of the unions case labels. It sets the current position to zero and causes component_count to return 1.
      Specified by:
      set_to_no_active_member in interface DynUnionOperations
      Throws:
      TypeMismatch - if the union has an explicit default case or if it uses the entire range of discriminator values for explicit case labels
      TypeMismatch

    • has_no_active_member

      public boolean has_no_active_member()
      Returns true if the union has no active member, that is, the unions value consists solely of its discriminator because the discriminator has a value that is not listed as an explicit case label. Calling this operation on a union that has a default case returns false. Calling this operation on a union that uses the entire range of discriminator values for explicit case labels returns false.
      Specified by:
      has_no_active_member in interface DynUnionOperations

    • discriminator_kind

      public TCKind discriminator_kind()
      Returns the TCKind value of the discriminators TypeCode.

      Returns the TCKind value of the currently active members TypeCode.
      Specified by:
      member_kind in interface DynUnionOperations
      Throws:
      InvalidValue - if the union does not have a currently active member
      InvalidValue

    • member

      public DynAny member() throws InvalidValue
      Returns the currently active member. Note that the returned reference remains valid only for as long as the currently active member does not change. Using the returned reference beyond the life time of the currently active member raises OBJECT_NOT_EXIST.
      Specified by:
      member in interface DynUnionOperations
      Throws:
      InvalidValue - if the union has no active member
      InvalidValue

    • member_name

      public String member_name() throws InvalidValue
      Returns the name of the currently active member. If the unions TypeCode does not contain a member name for the currently active member, the operation returns an empty string.
      Specified by:
      member_name in interface DynUnionOperations
      Throws:
      InvalidValue - if the union has no active member
      InvalidValue

    • type

      public TypeCode type()
      Returns the TypeCode associated with this DynAny object. A DynAny object is created with a TypeCode value assigned to it. This TypeCode value determines the type of the value handled through the DynAny object. Note that the TypeCode associated with a DynAny object is initialized at the time the DynAny is created and cannot be changed during lifetime of the DynAny object.
      Specified by:
      type in interface DynAnyOperations
      Returns:
      The TypeCode associated with this DynAny object

    • assign

      public void assign(DynAny dyn_any) throws TypeMismatch
      Initializes the value associated with a DynAny object with the value associated with another DynAny object. The current position of the target DynAny is set to zero for values that have components and to -1 for values that do not have components.
      Specified by:
      assign in interface DynAnyOperations
      Parameters:
      dyn_any -
      Throws:
      TypeMismatch - if the type of the passed DynAny is not equivalent to the type of target DynAny
      TypeMismatch

    • from_any

      public void from_any(Any value) throws TypeMismatch, InvalidValue
      Initializes the value associated with a DynAny object with the value contained in an any. The current position of the target DynAny is set to zero for values that have components and to -1 for values that do not have components.
      Specified by:
      from_any in interface DynAnyOperations
      Throws:
      TypeMismatch - if the type of the passed Any is not equivalent to the type of target DynAny
      InvalidValue - if the passed Any does not contain a legal value (such as a null string)
      TypeMismatch
      InvalidValue

    • to_any

      public Any to_any()
      Creates an any value from a DynAny object. A copy of the TypeCode associated with the DynAny object is assigned to the resulting any. The value associated with the DynAny object is copied into the any.
      Specified by:
      to_any in interface DynAnyOperations
      Returns:
      a new Any object with the same value and TypeCode

    • equal

      public boolean equal(DynAny dyn_any)
      Compares two DynAny values for equality. Two DynAny values are equal if their TypeCodes are equivalent and, recursively, all component DynAnys have equal values. The current position of the two DynAnys being compared has no effect on the result of equal.
      Specified by:
      equal in interface DynAnyOperations
      Returns:
      true of the DynAnys are equal, false otherwise

    • destroy

      public void destroy()
      Destroys a DynAny object. This operation frees any resources used to represent the data value associated with a DynAny object. It must be invoked on references obtained from one of the creation operations on the ORB interface or on a reference returned by DynAny.copy() to avoid resource leaks. Invoking destroy on component DynAny objects (for example, on objects returned by the current_component operation) does nothing. Destruction of a DynAny object implies destruction of all DynAny objects obtained from it. That is, references to components of a destroyed DynAny become invalid. Invocations on such references raise OBJECT_NOT_EXIST. It is possible to manipulate a component of a DynAny beyond the life time of the DynAny from which the component was obtained by making a copy of the component with the copy operation before destroying the DynAny from which the component was obtained.
      Specified by:
      destroy in interface DynAnyOperations

    • copy

      public DynAny copy()
      Creates a new DynAny object whose value is a deep copy of the DynAny on which it is invoked. The operation is polymorphic, that is, invoking it on one of the types derived from DynAny, such as DynStruct, creates the derived type but returns its reference as the DynAny base type.
      Specified by:
      copy in interface DynAnyOperations
      Returns:
      a deep copy of the DynAny object

      public DynAny get_dyn_any() throws TypeMismatch, InvalidValue
      Extracts the Any value contained in the Any represented by this DynAny and returns it wrapped into a new DynAny.
      Specified by:
      get_dyn_any in interface DynAnyOperations
      Throws:
      TypeMismatch - if the accessed component in the DynAny is of a type that is not equivalent to the requested type.

      InvalidValue

    • get_val

      public Serializable get_val() throws TypeMismatch, InvalidValue
      Extracts a Serializable object from this DynAny. The IDL ValueBase type is mapped to the Java Serializable type.
      Specified by:
      get_val in interface DynAnyOperations
      Throws:
      TypeMismatch - if the accessed component in the DynAny is of a type that is not equivalent to the requested type.

      InvalidValue - if this DynAny has components but has a current position of -1
      TypeMismatch
      InvalidValue

    • seek

      public boolean seek(int index)
      Sets the current position to index. The current position is indexed 0 to n-1, that is, index zero corresponds to the first component. The operation returns true if the resulting current position indicates a component of the DynAny and false if index indicates a position that does not correspond to a component. Calling seek with a negative index is legal. It sets the current position to -1 to indicate no component and returns false. Passing a non-negative index value for a DynAny that does not have a component at the corresponding position sets the current position to -1 and returns false.
      Specified by:
      seek in interface DynAnyOperations

    • rewind

      public void rewind()
      Is equivalent to seek(0).
      Specified by:
      rewind in interface DynAnyOperations

    • next

      public boolean next()
      Advances the current position to the next component. The operation returns true while the resulting current position indicates a component, false otherwise. A false return value leaves the current position at -1. Invoking next on a DynAny without components leaves the current position at -1 and returns false.
      Specified by:
      next in interface DynAnyOperations

    • component_count

      public int component_count()
      Returns the number of components of a DynAny. For a DynAny without components, it returns zero. The operation only counts the components at the top level. For example, if component_count is invoked on a DynStruct with a single member, the return value is 1, irrespective of the type of the member.
      • For sequences, the operation returns the current number of elements.
      • For structures, exceptions, and value types, the operation returns the number of members.
      • For arrays, the operation returns the number of elements.
      • For unions, the operation returns 2 if the discriminator indicates that a named member is active, otherwise, it returns 1.
      • For DynFixed and DynEnum, the operation returns zero.
      Specified by:
      component_count in interface DynAnyOperations

    • current_component

      public DynAny current_component() throws TypeMismatch
      Returns the DynAny for the component at the current position. It does not advance the current position, so repeated calls to current_component without an intervening call to rewind, next, or seek return the same component. The returned DynAny object reference can be used to get/set the value of the current component. If the current component represents a complex type, the returned reference can be narrowed based on the TypeCode to get the interface corresponding to the to the complex type. Calling current_component on a DynAny that cannot have components, such as a DynEnum or an empty exception, raises TypeMismatch. Calling current_component on a DynAny whose current position is -1 returns a nil reference. The iteration operations, together with current_component, can be used to dynamically compose an any value. After creating a dynamic any, such as a DynStruct, current_component and next can be used to initialize all the components of the value. Once the dynamic value is completely initialized, to_any creates the corresponding any value.
      Specified by:
      current_component in interface DynAnyOperations
      Throws:
      TypeMismatch - If called on a DynAny that cannot have components, such as a DynEnum or an empty exception
