All Implemented Interfaces:

SimpleFeatureType, AttributeType, ComplexType, FeatureType, PropertyType
```
public class VPFFeatureType
extends Object
implements SimpleFeatureType
```
A VPF feature type. Note that feature classes may contain one or more feature types. However, all of the feature types of a feature class share the same schema. A feature type will therefore delegate its schema related operations to its feature class.

  - isInline
```
public boolean isInline()
```
    Description copied from interface: ComplexType
    Indicates ability of XPath to notice this attribute.
    This facility is used to "hide" an attribute from XPath searches, while the compelx contents will still be navigated no additional nesting will be considered. It will be as if the content were "folded" inline resulting in a flatter nesting structure.
    Construct described using Java Interfaces:
```
 interface TestSample {
     String name;
     List measurement;
 }
 interface Measurement {
     long timestamp;
     Point point;
     long reading;
 }
 
```
    The above is can hold the following information:
```
 [ name="survey1",
   measurements=(
       [timestamp=3,point=(2,3), reading=4200],
       [timestamp=9,point=(2,4), reading=445600],
   )
 ]
 
```
    Out of the box this is represented to XPath as the following tree:
```
 root/name: survey1
 root/measurement[0]/timestamp:3
 root/measurement[0]/point: (2,3)
 root/measurement[0]/reading: 4200
 root/measurement[1]/timestamp:9
 root/measurement[2]/point: (2,4)
 root/measurement[3]/reading: 445600
 
```
    By inlining Measurement we can achive the following:
```
 root/name: survey1
 root/timestamp[0]:3
 root/point[0]: (2,3)
 root/reading[0]: 4200
 root/timestamp[1]:9
 root/point[1]: (2,4)
 root/reading[1] 445600
 
```
    Specified by:
    
    isInline in interface ComplexType
    
    Returns:
    
    true if attribute is to be considered transparent by XPath queries
  - getRestrictions
```
public List<Filter> getRestrictions()
```
    Description copied from interface: PropertyType
    
    List of restrictions used define valid values for properties of this property type.
    Each restriction is a Filter object in which the property is passed through. If Filter.evaluate(Object) returns true the restriction is met. If false is returned then the restriction has not been met and the property should be considered invalid. Remember to check getSuper().getRestrictions() as well.
    This method returns an empty set in the case of no restrictions and should not return null.
    
    Specified by:
    
    getRestrictions in interface PropertyType
    
    Returns:
    
    List used to validate allowable values.

    Specified by:
    
    isIdentified in interface FeatureType
    
    Returns:
    
    true
    
    See Also:

    Description copied from interface: PropertyType
    
    Human readable description of this property type.
    
    Specified by:
    
    getDescription in interface PropertyType
    
    Returns:
    
    Human readable description of this property type.
  - getName
```
public Name getName()
```
    Description copied from interface: PropertyType
    
    The name of the property type.
    Note that this is not the same name as Property.getName(), which is the name of the instance of the type, not the type itself.
    The returned name is a qualified name made up of two parts. The first a namespace uri (Name.getNamespaceURI(), and the second a local part (Name.getLocalPart().
    This value is never null.
    
    Specified by:
    
    getName in interface PropertyType
    
    Returns:
    
    The name of the property type.
  - getUserData
```
public Map<Object,Object> getUserData()
```
    Description copied from interface: PropertyType
    A map of "user data" which enables applications to store "application-specific" information against a property type.
    As an example, consider an application that builds a PropertyType from an xml schema. A useful bit of information to attach to the PropertyType is the original schema itself, in whatever construct it might be stored in:
```
 
 XSDComplexTypeDefinition complexTypeDef = ...;
 PropertyType type = buildPropertyType( complexTypeDef );

 type.getUserData().put( XSDComplexTypeDefintion.class, complexTypeDef );
 
 
```
    Specified by:
    
    getUserData in interface PropertyType
    
    Returns:
    
    A map of user data.
  - indexOf
```
public int indexOf(String name)
```
    Description copied from interface: SimpleFeatureType
    
    Returns the index of the attribute which matches the specified name.
    -1 is returned in the instance there is no attribute matching the specified name.
    
    Specified by:
    
    indexOf in interface SimpleFeatureType
    
    Parameters:
    
    name - The name of the attribute whose index to return.
    
    Returns:
    
    index of named attribute, or -1 if not found.
  - indexOf
```
public int indexOf(Name name)
```
    Description copied from interface: SimpleFeatureType
    
    Returns the index of the attribute which matches the specified name.
    -1 is returned in the instance there is no attribute matching the specified name.
    
    Specified by:
    
    indexOf in interface SimpleFeatureType
    
    Parameters:
    
    name - The name of the attribute whose index to return.
    
    Returns:
    
    index of named attribute, or -1 if not found.
