xml-box

This is a non-composite builder that construct a polygon geometry out of two coordinates.

builder type: non-composite.

geometry constructed: polygon geometry.

data parameters:

Data Name	Value	Required/ Optional
data-string	The string containing the coordinate data. Range: String	Required
axis-order	Indicates the axis for a coordinate. Range: A permutation of the numbers 1..N, where N is the number of dimensions. Each number is separated by a comma “,”. Default: “1,2,...,N”	Optional
dimension	The dimension of the coordinates. Range: String representing a positive integer, or the “implicit” literal, which forces the dimension to be automaticallly determined even if axis-order is specified. Default: When not specified the dimension will be automatically determined.	Optional
axis-separator	The string separating each axis of a coordinate in the data-string. Range: String | “whitespace” this includes the tab, newline, and space characters. Default: “,”	Optional
coord-separator	The string separating each coordinate in the data-string. Range: String Default: “whitespace” this includes the tab, newline, and space characters.	Optional
decimal	The string representing the decimal point for each real number in the data-string. Range: String Default: “.”	Optional
coordinate-system	Specifies the coordinate system name. If the expression sequence for the coordinate-system evaluates to the empty string, then the coordinate system for the feature being built will not be set. Range: String	Optional
name	Specifies the geometry’s name. Range: String	Optional

The following sequence of examples illustrates the usage of the xml-box builder.
