When reading or taking data with this reader, if you request a copy of the samples instead of a loan, and a string in a destination data sample is NULL, the middleware will allocate a new string for you of sufficient length to hold the received string. The new string will be allocated with DDS_String_alloc; the sample's destructor will delete it.
A non- NULL string is assumed to be allocated to sufficient length to store the incoming data. It will not be reallocated.
| DDS_KeyedString* DDS_KeyedString_new | ( | ) |
Constructor.
The default constructor initializes the newly created object with NULL key and value.
| DDS_KeyedString* DDS_KeyedString_new_w_size | ( | int | key_size, |
| int | size | ||
| ) |
Constructor that specifies the allocated sizes.
The allocated strings are initialized to empty ("").
| key_size | <<in>> Size of the allocated key string (with NULL-terminated character). Cannot be smaller than zero. |
| size | <<in>> Size of the allocated value string (with NULL-terminated character). Cannot be smaller than zero. |
| void DDS_KeyedString_delete | ( | DDS_KeyedString * | self | ) |
Destructor.
| DDS_ReturnCode_t DDS_KeyedStringTypeSupport_register_type | ( | DDS_DomainParticipant * | participant, |
| const char * | type_name | ||
| ) |
Allows an application to communicate to RTI Connext the existence of the DDS_KeyedString data type.
By default, The DDS_KeyedString built-in type is automatically registered when a DomainParticipant is created using the type_name returned by DDS_KeyedStringTypeSupport_get_type_name. Therefore, the usage of this function is optional and it is only required when the automatic built-in type registration is disabled using the participant property "dds.builtin_type.auto_register".
This function can also be used to register the same DDS_KeyedStringTypeSupport with a DDS_DomainParticipant using different values for the type_name.
If register_type is called multiple times with the same DDS_DomainParticipant and type_name, the second (and subsequent) registrations are ignored by the operation.
| participant | <<in>> the DDS_DomainParticipant to register the data type DDS_KeyedString with. Cannot be NULL. |
| type_name | <<in>> the type name under with the data type DDS_KeyedString is registered with the participant; this type name is used when creating a new DDS_Topic. (See DDS_DomainParticipant_create_topic.) The name may not be NULL or longer than 255 characters. |
| DDS_ReturnCode_t DDS_KeyedStringTypeSupport_unregister_type | ( | DDS_DomainParticipant * | participant, |
| const char * | type_name | ||
| ) |
Allows an application to unregister the DDS_KeyedString data type from RTI Connext. After calling unregister_type, no further communication using this type is possible.
type_name is registered with the participant and all DDS_Topic objects referencing the type have been destroyed. If the type is not registered with the participant, or if any DDS_Topic is associated with the type, the operation will fail with DDS_RETCODE_ERROR. | participant | <<in>> the DDS_DomainParticipant to unregister the data type DDS_KeyedString from. Cannot be NULL. |
| type_name | <<in>> the type name under with the data type DDS_KeyedString is registered with the participant. The name should match a name that has been previously used to register a type with the participant. Cannot be NULL. |
