holoscan.executors

This module provides a Python API for the C++ API Executor classes.

class holoscan.executors.GXFExecutor

Bases: holoscan.core._core.Executor

GXF-based executor class.

Attributes

context	The corresponding GXF context.
context_uint64	The corresponding GXF context represented as a 64-bit unsigned integer address
fragment	The fragment that the executor belongs to.

Methods

run(self, arg0)

Method that can be called to run the executor.

__init__(self: holoscan.executors._executors.GXFExecutor, app: holoscan.core._core.Fragment) → None

GXF-based executor class.

Parameters

appholoscan.core.Fragment

The fragment associated with the executor.

property context

The corresponding GXF context. This will be an opaque PyCapsule object.

property context_uint64

The corresponding GXF context represented as a 64-bit unsigned integer address

property fragment

The fragment that the executor belongs to.

Returns

nameholoscan.core.Fragment

run(self: holoscan.core._core.Executor, arg0: holoscan.graphs._graphs.Graph) → None

Method that can be called to run the executor.

holoscan.executors.create_input_port(fragment: holoscan.core._core.Fragment, gxf_context: capsule, eid: int, io_spec: holoscan.core._core.IOSpec) → None

Create and setup GXF components for an input port.

For a given input port specification, create a GXF Receiver component for the port and create a GXF SchedulingTerm component that is corresponding to the Condition of the port.

If there is no condition specified for the port, a default condition (MessageAvailableCondition) is created. It currently supports ConditionType::kMessageAvailable and ConditionType::kNone condition types.

Parameters

fragmentFragment

The fragment that this operator belongs to.

gxf_contextPyCapsule object

The operator’s associated GXF context.

eidint

The GXF entity ID.

io_specIOSpec

Input port specification.

holoscan.executors.create_output_port(fragment: holoscan.core._core.Fragment, gxf_context: capsule, eid: int, io_spec: holoscan.core._core.IOSpec) → None

Create and setup GXF components for an output port.

For a given output port specification, create a GXF Transmitter component for the port and create a GXF SchedulingTerm component that is corresponding to the Condition of the port.

If there is no condition specified for the port, a default condition (DownstreamMessageAffordableCondition) is created. It currently supports ConditionType::kDownstreamMessageAffordable and ConditionType::kNone condition types.

Parameters

fragmentFragment

The fragment that this operator belongs to.

gxf_contextPyCapsule object

The operator’s associated GXF context.

eidint

The GXF entity ID.

io_specIOSpec

Output port specification.
