Array

Synthèse

The array object can contain points and arrays and is used to construct geometry objects.

Syntaxe

 Array  ({items})

Paramètre	Explication	Type de données
items	Items can include a Point object, another Array object, or any iterable object that returns Point objects.	Object

Propriétés

Propriété	Explication	Type de données
count (Lecture seule)	The element count of the array.	Integer

Vue d’ensemble des méthodes

Méthode	Explication
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.

Méthodes

Exemple de code

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")
