This class provides access to set of Symbols. This is an optimised geometry group that is drawn with the same set of rendering at the same time.
Rendering attributes can be set directly to this geometry using the inherited TSLEntityBase::setRendering method. This is called 'Entity Rendering'.
Rendering can be applied to a large range of geometry using 'Feature Rendering' which is set by the datalayer using TSLDataLayer::addFeatureRendering which creates a featureID. The featureID can then have attributes applied to it using TSLDataLayer::setFeatureRendering.
A featureID can be applied to geometry on creation, or it can be added later using TSLEntityBase::featureID.
Valid Rendering Attributes for TSLMultiPoint:
The above is not a complete list, see TSLRenderingAttributeInt, TSLRenderingAttributeDouble and TSLRenderingAttributeBool for more details.

| bool TSLMultiPoint::addPart | ( | const TSLCoord & | coord, |
| int | pos = -1 ) |
Add a coordinate to the TSLMultiPoint.
| coord | the coordinate to add. |
| pos | the position at which to add the coordinate. By default the coordinate will be added after the current last coordinate. If the position entered is greater than the existing number of parts the coordinate is also added after the current last coordinate. |

static |
Creates a TSLMultiPoint containing the given coordinates.
Returns a pointer to the TSLMultiPoint or NULL on error.
featureID: the ID of the feature code to assign to the TSLMultiPoint. This is used when rendering map features if no specific attribute set has been created for the entity.
parts: a pointer to the TSLCoords the TSLMultiPoint will contain
numParts: the number of coordinates
