public class ChoiceGeometryTypeImpl extends AttributeTypeImpl implements ChoiceGeometryType, GeometryType
This is temporary and only for use by the parser. It should never be public or in common use.

Best to explain by Example.
Consider a choice between Polygon and MultiPolygon. It doesn't make sense to be a Geometry Attribute Type since normal attribute type inspection will allow users/clients to set Points and lines as legal attribute. For parsing purposes, this make the FeatureType a little more accurate. It is not perfect of course since The choice Line, Polygon and MultiPolygon still has to be of Type Geometry but it is a little better.

GeometryTypeThis method may return null, but this should only occur in cases where the
actual crs is not known. A common case is when a shapefile does not have an accompanied .prj
file.

public Object getDefaultValue()
AttributeDescriptorThis value is used when an attribute is created and no value for it is specified.
This value may be null. If it is non-null it should be an instance of of the
class specified by getType().getBinding().
public String getLocalName()
AttributeDescriptor
getName().getLocalPart().public int getMaxOccurs()
PropertyDescriptorThis value is a positive integer. A value of -1 means that the max number of
occurrences is unbounded.
public int getMinOccurs()
PropertyDescriptorThis value is always an integer greater than or equal to zero.
public boolean isNillable()
PropertyDescriptornull is an allowable value for the property.true if the property is allowed to be null, otherwise
false.Copyright © 1996–2021 Geotools. All rights reserved.
