Member Data Documentation

◆ mask

int mask

Describes the type of thread.

The meaning of each bit of the mask are defined by com.rti.dds.infrastructure.ThreadSettingsKind.

[default] 0, use default options of the OS

◆ priority

int priority

Thread priority.

Important: The interpretation of numeric thread priority values is different based on whether the priority is specified in your application code or in an XML QoS profile document. This is because QoS profile documents are intended to be usable across programming languages.

[range] java.lang.Thread.MIN_PRIORITY to MAX_PRIORITY if set programmatically in Java code [range] Platform-dependent - Consult Platform Notes for additional details. if set in a QoS profile document

◆ stack_size

int stack_size

The thread stack-size.

[range] Platform-dependent. Consult Platform Notes for additional details.

◆ cpu_list

final IntSeq cpu_list = new IntSeq()

The list of processors on which the thread(s) may run.

A sequence of integers that represent the set of processors on which the thread(s) controlled by this QoS may run. An empty sequence (the default) means the middleware wlll make no CPU affinity adjustments.

Note: This feature is currently only supported on a subset of architectures (see the Platform Notes). The API may change as more architectures are added in future releases.

This value is only relevant to the com.rti.dds.infrastructure.ReceiverPoolQosPolicy. It is ignored within other QoS policies that include com.rti.dds.infrastructure.ThreadSettings_t.

[default] Empty sequence

◆ cpu_rotation

ThreadSettingsCpuRotationKind cpu_rotation

Initial value:

=

ThreadSettingsCpuRotationKind.THREAD_SETTINGS_CPU_NO_ROTATION

Determines how processor affinity is applied to multiple threads.
