Built-in Geometry Builders

This section describes the built-in geometry builders available to the XML Reader. These custom geometry builders are format-specific and are described in their own sections. The XML Reader comes with the following built-in geometry builders:

• xml-point or xml-point-xy: is a non-composite builder that constructs a point geometry.
• xml-line: is non-composite builder that constructs a line geometry.
• xml-area: is a composite builder that constructs an area geometry.
• xml-donut: is a composite builder that constructs a donut area geometry.
• xml-aggregate: is a composite builder that constructs an aggregate geometry.
• xml-box: is a non-composite builder that constructs a polygon geometry from two coordinates.
• xml-text: is a composite builder that constructs a text geometry.
• xml-path: is a composite builder that constructs a path from line segments.
• xml-arc, xml-arc-by-center-point, and xml-elliptical-arc: are non-composite/composite builders that constructs arc geometry.
• xml-clothoid: is a non-composite/composite builder that constructs a clothoid geometry.
• xml-circle: is a non-composite builder that constructs an arc geometry based on a circle definition.
• xml-polygon: is a composite builder that constructs a polygon geometry.
• xml-face: is a composite builder that constructs a simple surface geometry.
• xml-composite-surface: is a composite builder that constructs a composite surface geometry

• xml-triangulated-surface: is a composite builder that constructs a mesh surface geometry

• xml-enclosed-surface: is a composite builder that constructs a simple solid geometry.
• xml-composite-solid: is a composite builder that constructs a composite solid geometry.
• xml-multi-point: is a composite builder that constructs a homogenous point aggregate geometry.
• xml-multi-curve: is a composite builder that constructs a homogenous curve aggregate geometry.
• xml-multi-area: is a composite builder that constructs a homogenous area aggregate geometry.
• xml-multi-text: is a composite builder that constructs an aggregate of text.
• xml-multi-surface: is a composite builder that constructs a homogenous surface geometry
• xml-multi-solid: is a composite builder that constructs a homogenous solid aggregate geometry.
• xml-null: is a non-composite builder that constructs the null geometry.
• xml-reverse-geometry: is a composite builder that reverses the order of coordinates.
• xml-geodesic-string: is non-composite builder that interpolates a sequence of geodesic control points into a line geometry.
• fme-geometry: is a non-composite builder that constructs various type of geometries from various types of geometry serialization.

The following sections describe each built-in builder and its data parameters.
