Class nokia.maps.util.Strip

Class Summary

This class represents a special array that contains objects, all of the same type, and each with the same properties. The objects are not added to the array as objects, but instead the array contains just the values of the properties of the objects. Each object is allocated one slot in the array for every property it contains. For example, if each object in the array has two properties called "x" and "y", then the length of the array is twice the number of objects added to it.

new nokia.maps.util.Strip (names, [data])

Method Summary

static stencil (template, [data]) This method creates a new instance of Strip by reusing the meta data of an existing strip object and an optional data array.

Field Summary

static nokia.maps.util.Strip LAT_LNG This property is a template for ["latitude", "longitude"] strips.

static nokia.maps.util.Strip X_Y This property is a template for ["x", "y"] strips.

Object[] data This property holds the array values.

String[] names This property holds an array of the names of the properties defined on each of the objects in the strip.

Object offsets This hashtable holds the relative offset of each object property held in the array (from 0 to n-1).

Constructor Detail

new nokia.maps.util.Strip(names, [data])

Parameters:

{String[]}	names	Array of names which are used to name objects in data array parameter.
{Object[]}	[data]: []	Array of values which are named repetitively according to names array parameter

Method Detail

static stencil (template, [data])

This method creates a new instance of Strip by reusing the meta data of an existing strip object and an optional data array.

Examples:

		strip1 = new Strip(["foo", "bar"], foobar1);
		strip2 = Strip.stencil(strip1, foobar2);

Parameters:

{nokia.maps.util.Strip}	template	A `Strip` to be used as a template for creating a new instance of `Strip`
{Object[]}	[data]: []	An array of data with which to populate the new instance

Field Detail

static nokia.maps.util.Strip LAT_LNG

This property is a template for ["latitude", "longitude"] strips.

static nokia.maps.util.Strip X_Y

This property is a template for ["x", "y"] strips.

Object[] data

This property holds the array values. To get the number of objects contained in the array, the length of the data array must be divided by the length of the names property, so:

		 size = arr.data.length / arr.names.length;

String[] names

This property holds an array of the names of the properties defined on each of the objects in the strip.

Object offsets

This hashtable holds the relative offset of each object property held in the array (from 0 to n-1).
