Method Detail

current_member_name

public String current_member_name()
                           throws TypeMismatch,
                                  InvalidValue

Returns the name of the member at the current position. This operation may return an empty string since the TypeCode of the value being manipulated may not contain the names of members.

Specified by:: current_member_name in interface DynStructOperations

Throws:: TypeMismatch - if the DynStruct represents an empty exception.; InvalidValue - if the current position does not indicate a member

current_member_kind

public TCKind current_member_kind()
                           throws TypeMismatch,
                                  InvalidValue

Returns the TCKind associated with the member at the current position.

Specified by:: current_member_kind in interface DynStructOperations

Throws:: TypeMismatch - if the DynStruct represents an empty exception.; InvalidValue - if the current position does not indicate a member

get_members

public NameValuePair[] get_members()

Returns a sequence of NameValuePairs describing the name and the value of each member in the struct associated with a DynStruct object. The sequence contains members in the same order as the declaration order of members as indicated by the DynStruct's TypeCode. The current position is not affected. The member names in the returned sequence will be empty strings if the DynStruct's TypeCode does not contain member names.

Specified by:: get_members in interface DynStructOperations

set_members

public void set_members(NameValuePair[] value)
                 throws TypeMismatch,
                        InvalidValue

Initializes the struct data value associated with a DynStruct object from a sequence of NameValuePairs. The operation sets the current position to zero if the passed sequences has non-zero length. Otherwise, if an empty sequence is passed, the current position is set to -1.

Members must appear in the NameValuePairs in the order in which they appear in the IDL specification of the struct as indicated by the DynStruct's TypeCode or they must be empty strings. The operation makes no attempt to assign member values based on member names.

Specified by:: set_members in interface DynStructOperations

Throws:: TypeMismatch - if the member names supplied in the passed sequence do not match the corresponding member name in the DynStruct's TypeCode and they are not empty strings; InvalidValue - if the passed sequence has a number of elements that disagrees with the number of members as indicated by the DynStruct's TypeCode

get_members_as_dyn_any

public NameDynAnyPair[] get_members_as_dyn_any()

Returns a sequence of NameDynAnyPairs describing the name and the value of each member in the struct associated with a DynStruct object. The sequence contains members in the same order as the declaration order of members as indicated by the DynStruct's TypeCode. The current position is not affected. The member names in the returned sequence will be empty strings if the DynStruct's TypeCode does not contain member names.

Specified by:: get_members_as_dyn_any in interface DynStructOperations

set_members_as_dyn_any

public void set_members_as_dyn_any(NameDynAnyPair[] value)
                            throws TypeMismatch,
                                   InvalidValue

Initializes the struct data value associated with a DynStruct object from a sequence of NameDynAnyPairs. The operation sets the current position to zero if the passed sequences has non-zero length. Otherwise, if an empty sequence is passed, the current position is set to -1.

Members must appear in the NameDynAnyPairs in the order in which they appear in the IDL specification of the struct as indicated by the DynStruct's TypeCode or they must be empty strings. The operation makes no attempt to assign member values based on member names.

Specified by:: set_members_as_dyn_any in interface DynStructOperations

Throws:: TypeMismatch - if the member names supplied in the passed sequence do not match the corresponding member name in the DynStruct's TypeCode and they are not empty strings; InvalidValue - if the passed sequence has a number of elements that disagrees with the number of members as indicated by the DynStruct's TypeCode

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

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)

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

insert_boolean

public void insert_boolean(boolean value)
                    throws TypeMismatch,

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

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
