Constructor Detail

AttributeTypeImpl

public AttributeTypeImpl(Name name,
                         Class<?> binding,
                         boolean identified,
                         boolean isAbstract,
                         List<Filter> restrictions,
                         AttributeType superType,
                         InternationalString description)

Method Detail

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:

Attribute#getID()

parse

public Object parse(Object value)
             throws IllegalArgumentException

Allows this AttributeType to convert an argument to its prefered storage type. If no parsing is possible, returns the original value. If a parse is attempted, yet fails (i.e. a poor decimal format) throw the Exception. This is mostly for use internally in Features, but implementors should simply follow the rules to be safe.

Parameters:

value - the object to attempt parsing of.

Returns:

value converted to the preferred storage of this AttributeType. If no parsing was possible then the same object is returned.

Throws:

IllegalArgumentException - if parsing is attempted and is unsuccessful.

createDefaultValue

public Object createDefaultValue()

getSuper

public AttributeType getSuper()

Description copied from interface: PropertyType

The parent type of the property type.

This method returns null if no super type is defined.

The super type may contain additional restrictions to be considered against properties of the the property type.

Specified by:

getSuper in interface AttributeType

Specified by:

getSuper in interface PropertyType

Overrides:

getSuper in class PropertyTypeImpl

Returns:

The parent or super type, or null.

See Also:

PropertyType.getSuper()

hashCode

public int hashCode()

Override of hashcode.

Specified by:

hashCode in interface PropertyType

Overrides:

hashCode in class PropertyTypeImpl

Returns:

getName().hashCode()

equals

public boolean equals(Object other)

Override of equals.

Specified by:

equals in interface PropertyType

Overrides:

equals in class PropertyTypeImpl

Parameters:

other - the object to be tested for equality.

Returns:

whether other is equal to this attribute Type.

toString

public String toString()

Overrides:

toString in class PropertyTypeImpl
