Detailed Description

Built-in topic reader's resource limits.

Defines the resources that can be used for a built-in-topic data reader.

A built-in topic data reader subscribes reliably to built-in topics containing declarations of new entities or updates to existing entities in the domain. Keys are used to differentiate among entities of the same type. RTI Data Distribution Service assigns a unique key to each entity in a domain.

Properties:

RxO = N/A
Changeable = NO

QoS:

DDS::DiscoveryConfigQosPolicy

Member Data Documentation

System::Int32 DDS::BuiltinTopicReaderResourceLimits_t::initial_samples

Initial number of samples.

This should be a value between 1 and initial number of instance of the built-in-topic reader, depending on how many instances are sending data concurrently.

[default] 64

[range] [1, 1 million], <= max_samples

System::Int32 DDS::BuiltinTopicReaderResourceLimits_t::max_samples

Maximum number of samples.

This should be a value between 1 and max number of instance of the built-in-topic reader, depending on how many instances are sending data concurrently. Also, it should not be less than initial_samples.

[default] DDS::LENGTH_UNLIMITED

[range] [1, 1 million] or DDS::LENGTH_UNLIMITED, >= initial_samples

System::Int32 DDS::BuiltinTopicReaderResourceLimits_t::initial_infos

Initial number of sample infos.

The initial number of info units that a built-in topic DDS::DataReader can have. Info units are used to store DDS::SampleInfo.

[default] 64

[range] [1, 1 million] <= max_infos

System::Int32 DDS::BuiltinTopicReaderResourceLimits_t::max_infos

Maximum number of sample infos.

The maximum number of info units that a built-in topic DDS::DataReader can use to store DDS::SampleInfo.

[default] DDS::LENGTH_UNLIMITED

[range] [1, 1 million] or DDS::LENGTH_UNLIMITED, >= initial_infos

System::Int32 DDS::BuiltinTopicReaderResourceLimits_t::initial_outstanding_reads

The initial number of outstanding reads that have not call finish yet on the same built-in topic DDS::DataReader.

[default] 2

[range] [1, 65536] or DDS::LENGTH_UNLIMITED <= max_outstanding_reads

System::Int32 DDS::BuiltinTopicReaderResourceLimits_t::max_outstanding_reads

The maximum number of outstanding reads that have not called finish yet on the same built-in topic DDS::DataReader.

[default] DDS::LENGTH_UNLIMITED

[range] [1, 65536] or DDS::LENGTH_UNLIMITED, >= initial_outstanding_reads

System::Int32 DDS::BuiltinTopicReaderResourceLimits_t::max_samples_per_read

Maximum number of samples that can be read/taken on a same built-in topic DDS::DataReader.

[default] 1024

[range] [1, 65536]
