Feature (Groovy Documentation)

geoscript.feature.Feature

A Feature contains a set of named attributes with values.
A Feature is created from a Map of name value pairs and an identifier.

Without a Schema (see below) the data types are inferred).
```
 Feature f = new Feature(['name': 'anvil', 'price': 100.0], 'widgets.1')
 
```
A Feature can also be created from a list of values, an identifier, and a Schema
```
 Schema s = new Schema('widgets', [['name','string'],['price','float']])
 Feature f = new Feature(['anvil', 100.0], '1', s)
 
```
A Feature can also be created from a Map of name value pairs, an identifier, and a Schema
```
 Schema s = new Schema('widgets', [['name','string'],['price','float']])
 Feature f = new Feature(['name': 'anvil', 'price': 100.0], '1', s)
 
```
