AbstractLazyAttributeTypeImpl (Geotools modules 27-SNAPSHOT API)

Object
- AbstractLazyAttributeTypeImpl

All Implemented Interfaces:

AttributeType, PropertyType

Direct Known Subclasses:

AbstractLazyComplexTypeImpl
```
public abstract class AbstractLazyAttributeTypeImpl
extends Object
implements AttributeType
```
A replacement for AttributeTypeImpl with lazy evaluation of super type, so types can be defined in any order. Note that type equality is defined by name, so do not allow different types with the same name to be put in any Collection.
Inspired by AttributeTypeImpl and PropertyTypeImpl.

```
public AbstractLazyAttributeTypeImpl(Name name,
                                     Class<?> binding,
                                     boolean identified,
                                     boolean isAbstract,
                                     List<Filter> restrictions,
                                     InternationalString description)
```
    Constructor arguments have the same meaning as in AttributeTypeImpl.
- Method Detail
  - buildSuper
```
public abstract AttributeType buildSuper()
```
    Subclasses must override this method to return the super type of this type or null if none. This method will only be called once at most.
    
    Returns:
    
    super type or null
  - isIdentified
```
public boolean isIdentified()
```
    Description copied from interface: AttributeType
    
    Indicates if the type is identified or not.
    If this method returns true, then the corresponding attribute must have a unique identifier, ie, Attribute#getID() must return a value, and cannot be null.
    
    Specified by:
    
    isIdentified in interface AttributeType
    
    Returns:
    
    true if the attribute is identified, otherwise false.
    
    See Also:
    
    AttributeType.isIdentified()
  - getSuper
```
public AttributeType getSuper()
```
    Description copied from interface: AttributeType
    
    Override of PropertyType.getSuper() which type narrows to AttributeType.
    
    Specified by:
    
    getSuper in interface AttributeType
    
    Specified by:
    
    getSuper in interface PropertyType
    
    Returns:
    
    The parent or super type, or null.
    
    See Also:
    
    AttributeType.getSuper()
  - 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.
    
    See Also:
    
    PropertyType.getName()
  - getBinding
```
public Class<?> getBinding()
```
    Description copied from interface: PropertyType
    
    The java class that values of properties of the property type are bound to.
    This value is never null.
    
    Specified by:
    
    getBinding in interface PropertyType
    
    Returns:
    
    The binding of the property type.
    
    See Also:
    
    PropertyType.getBinding()
  - isAbstract
```
public boolean isAbstract()
```
    Description copied from interface: PropertyType
    
    Flag indicating if the type is abstract or not.
    
    Specified by:
    
    isAbstract in interface PropertyType
    
    Returns:
    
    true if the type is abstract, otherwise false.
    
    See Also:
    
    PropertyType.isAbstract()
  - 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.
    
    See Also:
    
    PropertyType.getRestrictions()
  - getDescription
```
public InternationalString getDescription()
```
    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.
    
    See Also:
    
    PropertyType.getDescription()
  - 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.
    
    See Also:
    
    PropertyType.getUserData()
  - equals
```
public boolean equals(Object other)
```
    Equality by name. Yes, this may be a surprise to some client code, but how else do you define equality in the face of cyclic type definitions, without breaking encapsulation to analyse the full graph of types?
    
    Specified by:
    
    equals in interface PropertyType
    
    Overrides:
    
    equals in class Object
    
    Returns:
    
    true if other is a PropertyType with the same name
    
    See Also:
    
    Object.equals(java.lang.Object)
  - hashCode
```
public int hashCode()
```
    Description copied from interface: PropertyType
    
    Hashcode override based on PropertyType.getName().
    
    Specified by:
    
    hashCode in interface PropertyType
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    getName().hashCode()
    
    See Also:
    
    Object.hashCode()
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
    
    See Also:
    
    Object.toString()
