Examples of org.geotools.feature.simple.SimpleFeatureTypeBuilder

org.geotools.feature.simple.SimpleFeatureTypeBuilder
e the builder SimpleTypeBuilder builder = new SimpleTypeBuilder(); //set global state builder.setName( "testType" ); builder.setNamespaceURI( "http://www.geotools.org/" ); builder.setSRS( "EPSG:4326" ); //add attributes builder.add( "intProperty", Integer.class ); builder.add( "stringProperty", String.class ); builder.add( "pointProperty", Point.class ); //add attribute setting per attribute state builder.minOccurs(0).maxOccurs(2).nillable(false).add("doubleProperty",Double.class); //build the type SimpleFeatureType featureType = builder.buildFeatureType();
This builder builds type by maintaining state. Two types of state are maintained: Global Type State and Per Attribute State. Methods which set global state are named set<property>(). Methods which set per attribute state are named <property>(). Furthermore calls to per attribute

Global state is reset after a call to {@link #buildFeatureType()}. Per attribute state is reset after a call to {@link #add}.

A default geometry for the feature type can be specified explictly via {@link #setDefaultGeometry(String)}. However if one is not set the first geometric attribute ( {@link GeometryType}) added will be resulting default. So if only specifying a single geometry for the type there is no need to call the method. However if specifying multiple geometries then it is good practice to specify the name of the default geometry type. For instance:
```
 builder.add( "pointProperty", Point.class ); builder.add( "lineProperty", LineString.class ); builder.add( "polygonProperty", Polygon.class ); builder.setDefaultGeometry( "lineProperty" ); 
```
