public class DynValuePOATie extends DynValuePOA
DynValue objects support the manipulation of IDL non-boxed value types. The DynValue interface can represent both null and non-null value types. For a DynValue representing a non-null value type, the DynValue's components comprise the public and private members of the value type, including those inherited from concrete base value types, in the order of definition. A DynValue representing a null value type has no components and a current position of -1.Warning: Indiscriminantly changing the contents of private value type members can cause the value type implementation to break by violating internal constraints. Access to private members is provided to support such activities as ORB bridging and debugging and should not be used to arbitrarily violate the encapsulation of the value type.

-
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.- 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.- Parameters:
dyn_any
- 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
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.- Parameters:
value

- 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.- 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.
-
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.- Returns:
- a deep copy of the DynAny object

- Throws:
TypeMismatch
- if the accessed component in the DynAny is of a type that is not equivalent to the requested type.TypeMismatch
- if called on a DynAny whose current component itself has componentsInvalidValue
- if this DynAny has components but has a current position of -1
-
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.- Parameters:
index
- position to set to- Returns:
- if there is a component at the specified index
-
rewind
public void rewind()
Is equivalent to seek(0).
-
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.- Returns:
- if the resulting position indicates a component
-
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.
- Returns:
- the number of components
-
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.- Returns:
- the DynAny at the current position
- Throws:
TypeMismatch
