public interface DynStructOperations
extends DynAnyOperations

DynStruct objects support the manipulation of IDL struct and exception values. Members of the exceptions are handled in the same way as members of a struct.

Method Summary

Modifier and Type	Method	Description
TCKind	current_member_kind()	Returns the TCKind associated with the member at the current position.
String	current_member_name()	Returns the name of the member at the current position.
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.
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.
void	set_members(NameValuePair[] value)	Initializes the struct data value associated with a DynStruct object from a sequence of NameValuePairs.
void	set_members_as_dyn_any(NameDynAnyPair[] value)	Initializes the struct data value associated with a DynStruct object from a sequence of NameDynAnyPairs.

Method Detail

current_member_name

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.

Throws:

TypeMismatch - if the DynStruct represents an empty exception.

InvalidValue - if the current position does not indicate a member

current_member_kind

TCKind current_member_kind()
                    throws TypeMismatch,
                           InvalidValue

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

Throws:

TypeMismatch - if the DynStruct represents an empty exception.

InvalidValue - if the current position does not indicate a member

get_members

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.

set_members

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.

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

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.

set_members_as_dyn_any

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.

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
