Attributes Documentation
num_parameters
The number of parameter values this node requires at sampling time.
outgoing_register_type
The virtual gate type of outgoing registers.
parameter_idxs
Which evaluated parameter expressions this node needs access to at sampling time.
trace_info
Debug trace information linking this node back to its originating box(es).
Populated only when the samplex was built with debug=True. Contains annotation metadata such as tag and inject-noise refs from the box(es) that produced this node. This information is not serialized.
Methods Documentation
get_style
instantiates
instantiates() → dict[str, tuple[int, VirtualType]]
Return a manifest of new virtual registers that this node instantiates.
- To change the type or size of a register, both instantiate and remove it.
- Do not specify
reads_from()orwrites_to()for an instantiated register, these powers are implicit.
outputs_to
reads_from
reads_from() → dict[str, tuple[set[int], VirtualType]]
Return a manifest of which virtual register values this node needs to read from.
removes
removes() → set[str]
Return a manifest of virtual registers that this node removes.
It is assumed that registers are removed as a last step; it is not ill-defined to read and write from a removed register.
validate_and_update
validate_and_update(register_descriptions: dict[str, tuple[int, VirtualType]])
Validate provided register descriptions are compatible, update with changes.
This method can be used by a samplex to determine when a node execution order has well-defined dependencies before sampling begins.
Parameters
register_descriptions – A map from existing register names to their size and type.
writes_to
writes_to() → dict[str, tuple[set[int], VirtualType]]
Return a manifest of which virtual register values this node needs to write to.
