概要
The array object can contain points and arrays and is used to construct geometry objects.
構文
Array ({items})| パラメーター | 説明 | データ タイプ |
items | Items can include a list, a Point object, or another Array object. | Object |
プロパティ
| プロパティ | 説明 | データ タイプ |
| count (読み取り専用) | The element count of the array. | Integer |
手法の概要
| 手法 | 説明 |
| add (value) | Adds a Point or Array object to the end of the array. |
| append (value) | Appends an object to the array in the last position. |
| clone (point_object) | Clone the Point object. |
| extend (items) | Extends the array by appending elements. |
| getObject (index) | Returns the object at the given index position in the array. The getObject method is equivalent to indexing an object; that is, obj.getObject(0) is equivalent to obj[0]. |
| insert (index, value) | Adds an object to the Array object at the specified index. |
| next () | Returns the next object at the current index. |
| remove (index) | Removes the object at the specified index position from the array. |
| removeAll () | Removes all values and creates an empty object. |
| replace (index, value) | Replaces the object at the specified index position in the Array object. |
| reset () | Sets the current enumeration index (used by the next method) back to the first element. |

コードのサンプル
Array example
Create a polyline feature class from scratch.
import arcpy
# A list of features and coordinate pairs
feature_info = [[[1, 2], [2, 4], [3, 7]],
[[6, 8], [5, 7], [7, 2], [9, 5]]]
# A list that will hold each of the Polyline objects
features = []
for feature in feature_info:
# Create a Polyline object based on the array of points
# Append to the list of Polyline objects
features.append(
arcpy.Polyline(
arcpy.Array([arcpy.Point(*coords) for coords in feature])))
# Persist a copy of the Polyline objects using CopyFeatures
arcpy.CopyFeatures_management(features, "c:/geometry/polylines.shp")
