pygrenade_vx.common.PartitionedVertex

class pygrenade_vx.common.PartitionedVertex

Bases: pygrenade_common.Vertex

__init__(*args, **kwargs): Initialize self. See help(type(self)) for accurate signature.

Methods

`__init__`(args, *kwargs)	Initialize self.
`get_execution_instance_on_executor`(self)	Get execution instance on executor.
`get_strong_component_invariant`(self)	Get invariant of vertex which is required to be equal across its strong component.
`set_execution_instance_on_executor`(self, value)	Set execution instance on executor.
`valid_edge_from`(self, source, edge)	Get whether the edge from the source vertex to this vertex is valid.
`valid_edge_to`(self, target, edge)	Get whether the edge to the target vertex from this vertex is valid.

class StrongComponentInvariant

Bases: pygrenade_common.Vertex.StrongComponentInvariant

copy(self: pygrenade_common.PartitionedVertex.StrongComponentInvariant) → pygrenade_common.Vertex.StrongComponentInvariant

move(self: pygrenade_common.PartitionedVertex.StrongComponentInvariant) → pygrenade_common.Vertex.StrongComponentInvariant

get_execution_instance_on_executor(self: pygrenade_common.PartitionedVertex) → Optional[pygrenade_common.ExecutionInstanceOnExecutor]: Get execution instance on executor.

get_strong_component_invariant(self: pygrenade_common.PartitionedVertex) → pygrenade_common.Vertex.StrongComponentInvariant: Get invariant of vertex which is required to be equal across its strong component.

set_execution_instance_on_executor(self: pygrenade_common.PartitionedVertex, value: Optional[pygrenade_common.ExecutionInstanceOnExecutor]) → None: Set execution instance on executor. If a derived class is only conditionally partitionable, this method can be overwritten to throw an error if the vertex is not partitionable, but a non-null value is given.

valid_edge_from(self: pygrenade_common.PartitionedVertex, source: pygrenade_common.Vertex, edge: pygrenade_common.Edge) → bool: Get whether the edge from the source vertex to this vertex is valid. This is the case if the execution instance transition matches the expectation when the source vertex is a partitioned vertex (in addition to the common requirements of the Vertex).

valid_edge_to(self: pygrenade_common.PartitionedVertex, target: pygrenade_common.Vertex, edge: pygrenade_common.Edge) → bool: Get whether the edge to the target vertex from this vertex is valid. This is the case if the execution instance transition matches the expectation when the target vertex is a partitioned vertex (in addition to the common requirements of the Vertex).
