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 interfaceDynAnyOperations
- Returns:
- The TypeCode associated with this DynAny object

assign
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:

- DynAny value to assign to this object- Throws:
TypeMismatch
- if the type of the passed DynAny is not equivalent to the type of target DynAny

from_any
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:

equal
in interfaceDynAnyOperations
- Parameters:
dyn_any
- the value to compare to- 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 interfaceDynAnyOperations
-

copy
in interfaceDynAnyOperations
- Returns:
- a deep copy of the DynAny object

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:

in interfaceDynAnyOperations
- Returns:
- the number of components
-
current_component
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:

- Returns:
- the DynAny at the current position
- Throws:
TypeMismatch
- If called on a DynAny that cannot have components, such as a DynEnum or an empty exception
