lattice module

Define LATTICE and LATTICE_END instructions.

class Lattice(line: DatLine, dat_idx: int | None = None, **kwargs: str)

Bases: Command

Used to get the number of elements per lattice.

is_implemented: bool = True

n_attributes: int | range | Collection = (1, 2)

__init__(line: DatLine, dat_idx: int | None = None, **kwargs: str) → None: Save lattice structure.

set_influenced_elements(instructions: list[Instruction], **kwargs: float) → None

Determine the index of the elements concerned by apply().

Here, this is all the elements between this command and the next LATTICE or LATTICE_END instruction.

apply(instructions: list[Instruction], **kwargs: float) → list[Instruction]: Set lattice section number of elements in current lattice.

_current_section_number(instructions: list[Instruction]) → int: Get section number of self.

_current_lattice_number(instructions: list[Instruction], index: int) → int

Get lattice number of current object.

We look for Element in instructions in reversed order, starting from self. We take the first non negative lattice index that we find, and return it + 1. If we do not find anything, this is because no Element had a defined lattice number before.

This approach allows for Element without a lattice number, as for examples drifts between a LatticeEnd and a Lattice.

_abc_impl = <_abc._abc_data object at 0x7f36fbb58fc0>

class LatticeEnd(line: DatLine, dat_idx: int | None = None, **kwargs: str)

Bases: Command

Define the end of lattice.

is_implemented: bool = True

n_attributes: int | range | Collection = 0

__init__(line: DatLine, dat_idx: int | None = None, **kwargs: str) → None: Call mother __init__ method.

set_influenced_elements(instructions: list[Instruction], **kwargs: float) → None

Determine the index of the elements concerned by apply().

Here, this is all the elements that are between this command and the next LATTICE instruction.

_abc_impl = <_abc._abc_data object at 0x7f36f9858d40>

apply(instructions: list[Instruction], **kwargs: float) → list[Instruction]: Reset the lattice index of every influenced element.

As for now, the effect of this command will be overriden by the _force_a_lattice_for_every_element. See how I should handle this…
