Various settings that configure how a DDS::DomainParticipant 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 DDS::DomainParticipant is allowed to dynamically allocate memory as needed as users create local Entities such as DDS::DataWriter and DDS::DataReader or as the participant discovers new applications to store their information. By setting fixed values for the maximum parameters in this QosPolicy, you can bound the memory that can be allocated by a DomainParticipant. In addition, by setting the initial values to the maximum values, you can reduce the amount of memory allocated by DomainParticipants after the initialization period. Notice that memory can still be allocated dynamically after the initialization period. For example, when a new local DDS::DataWriter or DDS::DataReader is created, the initial memory required for its queue is allocated dynamically.
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 DDS::DomainParticipant to another, a DDS::DomainParticipant 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_object_max_serialized_length.
This QoS policy is an extension to the DDS standard.

[default] 256
[range] [0,256]
System::Int32 DDS::DomainParticipantResourceLimitsQosPolicy::type_code_max_serialized_length |
Maximum size of serialized string for type code.
This parameter is an alternative to DDS::DomainParticipantResourceLimitsQosPolicy::type_object_max_serialized_length for limiting the size of the type code that a DDS::DomainParticipant 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 large type codes. So it is common for users to set this parameter to a large value, if used (by default, it is set to 0). 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. Note: TypeObject is now the standard method of exchanging type information in RTI Connext. It is recommended to use DDS::DomainParticipantResourceLimitsQosPolicy::type_object_max_serialized_length to configure the maximum serialized type object string.

[range] [0,0xffff]
System::Int32 DDS::DomainParticipantResourceLimitsQosPolicy::type_object_max_serialized_length |
The maximum length, in bytes, that the buffer to serialize a TypeObject can consume.
This parameter limits the size of the TypeObject that a DomainParticipant is able to propagate. Since TypeObjects 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 TypeObjects larger than the default maximum of 8192 bytes. This field allows you to specify a larger value. The desired size for a given DDS::TypeCode can be obtained using DDS::TypeCode::get_type_object_serialized_size.
[default] 8192
[range] [0,0x7fffffff]
System::Int32 DDS::DomainParticipantResourceLimitsQosPolicy::serialized_type_object_dynamic_allocation_threshold |

Above this threshold, the memory for a TypeObject is allocated dynamically. Below it, the memory is obtained from a pool of fixed-size buffers. The size of the buffers is equal to this threshold.
In case DDS::DomainParticipantResourceLimitsQosPolicy::type_object_max_serialized_length is different than DDS::ResourceLimitsQosPolicy::LENGTH_UNLIMITED and is smaller than DDS::DomainParticipantResourceLimitsQosPolicy::serialized_type_object_dynamic_allocation_threshold: DDS::DomainParticipantResourceLimitsQosPolicy::serialized_type_object_dynamic_allocation_threshold will be adjusted to DDS::DomainParticipantResourceLimitsQosPolicy::type_object_max_serialized_length.

Settings applied to the allocation of information about DDS::TopicQuery objects created by other participants and discovered by this participant.
When the participant receives a new topic query that would make the current count go above max_count
, it is not processed until the current count drops (i.e. another topic query is cancelled). The topic query stays in the Built-in ServiceRequest DataReader queue until it can be processed or it is cancelled.
[default] initial_count = 1; max_count = DDS::ResourceLimitsQosPolicy::LENGTH_UNLIMITED; incremental_count = -1
[range] See allowed ranges in struct DDS::AllocationSettings_t
System::Int32 DDS::DomainParticipantResourceLimitsQosPolicy::remote_topic_query_hash_buckets |
Number of hash buckets for remote TopicQueries.
[default] 1
[range] [1, 10000]
System::Int32 DDS::DomainParticipantResourceLimitsQosPolicy::writer_data_tag_list_max_length |
System::Int32 DDS::DomainParticipantResourceLimitsQosPolicy::writer_data_tag_string_max_length |
Maximum string length of the data tags associated with a DDS::DataWriter.
The string length is defined as the cumulative length in bytes, including the null terminating characters, of all the pairs (name, value) associated with the DDS::DataWriter data tags.
[default] 0
[range] [0,0xffff]
System::Int32 DDS::DomainParticipantResourceLimitsQosPolicy::reader_data_tag_list_max_length |
System::Int32 DDS::DomainParticipantResourceLimitsQosPolicy::reader_data_tag_string_max_length |
Maximum string length of the data tags associated with a DDS::DataReader.
The string length is defined as the cumulative length in bytes, including the null terminating characters, of all the pairs (name, value) associated with the DDS::DataReader data tags.
[default] 0
