Field Documentation

DDS_Long DDS_DataWriterResourceLimitsQosPolicy::max_remote_readers

The maximum number of remote readers for which the writer will maintain state and communication.

[default] 16

[range] [1, 100000000]

DDS_Long DDS_DataWriterResourceLimitsQosPolicy::max_routes_per_reader

The maximum number of routes the writer will send to per matched reader.

[default] 2

[range] [1, 2147483647]

DDS_Long DDS_DataWriterResourceLimitsQosPolicy::writer_loaned_sample_allocation

Represents the amount of loanable samples managed by a DDS_DataWriter.

The number of samples loaned by a DDS_DataWriter via FooDataWriter_get_loan is limited by DDS_DataWriterResourceLimitsQosPolicy::writer_loaned_sample_allocation. FooDataWriter_get_loan returns NULL if and only if DDS_ResourceLimitsQosPolicy::max_samples samples have been loaned, and none of those samples has been written with FooDataWriter_write or discarded via FooDataWriter_discard_loan.

[default] (DDS_ResourceLimitsQosPolicy::max_samples + 1);

[range] [1, 1000000]

DDS_Boolean DDS_DataWriterResourceLimitsQosPolicy::initialize_writer_loaned_sample

Whether or not to initialize loaned samples returned by a DDS_DataWriter.

[default] DDS_BOOLEAN_FALSE
