CircularMapping class

class laygo2.object.grid.CircularMapping(elements=array([0]), dtype=<class 'int'>)

Bases: object

Basic circular mapping class (index number expands infinitely).

Example

>>> from laygo2.object.grid import Circularmapping
>>> map = CircularMapping(elements=[100, 200, 300])
>>> print(map[0])
100
>>> print(map[2])
300
>>> print(map[4])
200
>>> print(map[-3])
100
>>> print(map[[2, 3, -2])
[300, 100, 200]
>>> print(map[2:7])
[300, 100, 200, 300, 100]

Public Data Attributes:

elements	getter of elements.
shape	The shape of circular mapping.

Public Methods:

dtype

alias of int

__init__(elements=array([0]), dtype=<class 'int'>)

Constructor function of CircularMapping class.

Parameters:

• elements (list) – elements.

• dtype (type) – data type of elements.

Example

>>> from laygo2.object.grid import CircularMapping
>>> elements = [0, 35, 85, 130, 180]
>>> cm = CircularMapping(elements)
>>> cm.shape
[5]
>>> cm[5]
35
>>> cm[0:10]
[0, 35, 85, 130, 0, 35, 85, 130, 0, 35]

append(elem)

Append elements to the mapping.

concatenate(obj)

copy()

Copy the object.

flip()

Flip the elements of the object.

get_elements()

numpy.ndarray: getter of elements.

set_elements(value)

numpy.ndarray: setter of elements.

summarize()

Return the summary of the object information.

_elements = None

Array consisting of the elements of circular mapping.

Example

>>> from laygo2.object.grid import CircularMapping
>>> elements = [0, 35, 85, 130, 180]
>>> cm = CircularMapping(elements)
>>> cm.elements
[0, 35, 85, 130, 180]

Type:
