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")
