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 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 DDS_DomainParticipant. 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 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_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 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 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.
[default] 2048
[range] [0,0xffff]
| DDS_Long 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 3072 bytes. This field allows you to specify a larger value.
[default] 3072
[range] [0,0x7fffffff]
| DDS_Long DDS_DomainParticipantResourceLimitsQosPolicy::type_object_max_deserialized_length |
The maximum number of bytes that a deserialized TypeObject can consume.
This parameter limits the size of the TypeObject that a DomainParticipant is able to store.
[default] DDS_LENGTH_UNLIMITED
[range] [0,0x7fffffff] or DDS_LENGTH_UNLIMITED
| DDS_Long DDS_DomainParticipantResourceLimitsQosPolicy::deserialized_type_object_dynamic_allocation_threshold |
A threshold, in bytes, for dynamic memory allocation for the deserialized TypeObject.
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.
[default] 4096
[range] [0,0x7fffffff] <= DDS_DomainParticipantResourceLimitsQosPolicy::type_object_max_deserialized_length
| DDS_Long DDS_DomainParticipantResourceLimitsQosPolicy::contentfilter_property_max_length |
This field is the maximum length of all data related to a Content-filtered topic.
This is the sum of the length of the ContentFilteredTopic name, the length of the related topic name, the length of the filter expression, the length of the filter parameters, and the length of the filter name. The maximum number of combined characters should account for a terminating NULL ('\0') character for each string.

[range] [0,0xffff]
| DDS_Long DDS_DomainParticipantResourceLimitsQosPolicy::participant_property_string_max_length |
Maximum string length of the properties associated with the DDS_DomainParticipant.
The string length is defined as the cumulative length in bytes, including the null terminating characters, of all the pair (name,value) associated with the DDS_DomainParticipant properties.
[default] 2048
[range] [0,0xffff]
| DDS_Long DDS_DomainParticipantResourceLimitsQosPolicy::writer_property_list_max_length |
| DDS_Long DDS_DomainParticipantResourceLimitsQosPolicy::writer_property_string_max_length |
Maximum string length of the properties associated with a DDS_DataWriter.
