NAME

orber_tc - Help functions for IDL typecodes

DESCRIPTION

This module contains some functions that gives support in creating IDL typecodes that can be used in for example the any types typecode field. For the simple types it is meaningless to use this API but the functions exist to get the interface complete.

The type TC used below describes an IDL type and is a tuple according to the to the Erlang language mapping.

EXPORTS

null() -> TC

void() -> TC

short() -> TC

unsigned_short() -> TC

long() -> TC

unsigned_long() -> TC

long_long() -> TC

unsigned_long_long() -> TC

wchar() -> TC

float() -> TC

double() -> TC

boolean() -> TC

char() -> TC

octet() -> TC

any() -> TC

typecode() -> TC

principal() -> TC

These functions return the IDL typecodes for simple types.

object_reference(Id, Name) -> TC

Types
Id = string()

the repository ID

Name = string()

the type name of the object

Function returns the IDL typecode for object_reference.

struct(Id, Name, ElementList) -> TC

Types
Id = string()

the repository ID

Name = string()

the type name of the struct

ElementList = [{MemberName, TC}]

a list of the struct elements

MemberName = string()

the element name

Function returns the IDL typecode for struct.

union(Id, Name, DiscrTC, Default, ElementList) -> TC

Types
Id = string()

the repository ID

Name = string()

the type name of the union

DiscrTC = TC

the typecode for the unions discriminant

Default = integer()

a value that indicates which tuple in the element list that is default (value < 0 means no default)

ElementList = [{Label, MemberName, TC}]

a list of the union elements

Label = term()

the label value should be of the DiscrTC type

MemberName = string()

the element name

Function returns the IDL typecode for union.

enum(Id, Name, ElementList) -> TC

Types
Id = string()

the repository ID

Name = string()

the type name of the enum

ElementList = [MemberName]

a list of the enums elements

MemberName = string()

the element name

Function returns the IDL typecode for enum.

string(Length) -> TC

Types
Length = integer()

the length of the string (0 means unbounded)

Function returns the IDL typecode for string.

wstring(Length) -> TC

Types
Length = integer()

the length of the wstring (0 means unbounded)

Function returns the IDL typecode for wstring.

fixed(Digits, Scale) -> TC

Types
Digits = Scale = integer()

the digits and scale parameters of a Fixed type

Function returns the IDL typecode for fixed.

sequence(ElemTC, Length) -> TC

Types
ElemTC = TC

the typecode for the sequence elements

Length = integer()

the length of the sequence (0 means unbounded)

Function returns the IDL typecode for sequence.

array(ElemTC, Length) -> TC

Types
ElemTC = TC

the typecode for the array elements

Length = integer()

the length of the array

Function returns the IDL typecode for array.

alias(Id, Name, AliasTC) -> TC

Types
Id = string()

the repository ID

Name = string()

the type name of the alias

AliasTC = TC

the typecode for the type which the alias refer to

Function returns the IDL typecode for alias.

exception(Id, Name, ElementList) -> TC

Types
Id = string()

the repository ID

Name = string()

the type name of the exception

ElementList = [{MemberName, TC}]

a list of the exception elements

MemberName = string()

the element name

Function returns the IDL typecode for exception.

get_tc(Object) -> TC

get_tc(Id) -> TC

Types
Object = record()

an IDL specified struct, union or exception

Id = string()

the repository ID

If the get_tc/1 gets a record that is and IDL specified struct, union or exception as a parameter it returns the typecode.

If the parameter is a repository ID it uses the Interface Repository to get the typecode.

check_tc(TC) -> boolean()

Function checks the syntax of an IDL typecode.
