Detailed Description

Various settings that configure how a DDSDomainParticipant allocates and uses physical memory for internal resources, including the maximum sizes of various properties.

This QoS policy sets maximum size limits on variable-length parameters used by the participant and its contained Entities. It also controls the initial and maximum sizes of data structures used by the participant to store information about locally-created and remotely-discovered entities (such as DataWriters/DataReaders), as well as parameters used by the internal database to size the hash tables it uses.

By default, a DDSDomainParticipant is allowed to dynamically allocate memory as needed as users create local Entities such as DDSDataWriter and DDSDataReader objects or as the participant discovers new applications. By setting fixed values for the maximum parameters in this QoS policy, you can bound the memory that can be allocated by a DDSDomainParticipant. In addition, by setting the initial values to the maximum values, you can prevent DomainParticipants from allocating memory after the initialization period.

The maximum sizes of different variable-length parameters such as the number of partitions that can be stored in the DDS_PartitionQosPolicy, the maximum length of data store in the DDS_UserDataQosPolicy and DDS_GroupDataQosPolicy, and many others can be changed from their defaults using this QoS policy. However, it is important that all DomainParticipants that need to communicate with each other use the same set of maximum values. Otherwise, when these parameters are propagated from one DDSDomainParticipant to another, a DDSDomainParticipant with a smaller maximum length may reject the parameter, resulting in an error.

An important parameter in this QoS policy that is often changed by users is DDS_DomainParticipantResourceLimitsQosPolicy::type_code_max_serialized_length.

This QoS policy is an extension to the DDS standard.

DDS_Long DDS_DomainParticipantResourceLimitsQosPolicy::type_code_max_serialized_length

Maximum size of serialized string for type code.

This parameter limits the size of the type code that a DDSDomainParticipant is able to store and propagate for user data types. Type codes can be used by external applications to understand user data types without having the data type predefined in compiled form. However, since type codes contain all of the information of a data structure, including the strings that define the names of the members of a structure, complex data structures can result in type codes larger than the default maximum of 2048 bytes. So it is common for users to set this parameter to a larger value. However, as with all parameters in this QoS policy defining maximum sizes for variable-length elements, all DomainParticipants in the same domain should use the same value for this parameter.
