Array

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 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.
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")
