17.2.8 Type Codes for Built-in Types
The type codes associated with the built-in types are generated from the following IDL type definitions:
module DDS {
/* String */
struct String {
string<max_size> value;
};
/* KeyedString */
struct KeyedString {
@key string<max_size> key;
string<max_size> value;
};
/* Octets */
struct Octets {
sequence<octet, max_size> value;
};
/* KeyedOctets */
struct KeyedOctets {
@key string<max_size> key;
sequence<octet, max_size> value;
};
};
The maximum size (max_size) of the strings and sequences that will be included in the type code definitions can be configured on a per-DomainParticipant-basis by using the properties in Table 17.2 Properties for Allocating Size of Built-in Types, per DomainParticipant.

String
|
dds.builtin_type.string.max_size
|
Maximum size of the strings published by the DataWriters and received by the DataReaders belonging to a DomainParticipant (includes the NULL-terminated character).
Default: 1024
|
|
KeyedString
|
dds.builtin_type.keyed_string.
max_key_size
|
Maximum size of the keys used by the DataWriters and DataReaders belonging to a DomainParticipant (includes the NULL-terminated character).
Default: 1024
|
|
dds.builtin_type.keyed_string.
max_size
|
Maximum size of the strings published by the DataWriters and received by the DataReaders belonging to a DomainParticipant using the built-in type (includes the NULL-terminated character).
Default: 1024
|
|
Octets
|
dds.builtin_type.octets.max_size
