Class Point2DPropertyType

java.lang.Object

dk.heick.properties.PropertyType<Point2D>

dk.heick.properties.types.Point2DPropertyType

All Implemented Interfaces:

Serializable

public class Point2DPropertyType
extends PropertyType<Point2D>

PropertyType that validates to a dk.heick.properties.types.custom.Point2D value.
The string must contain two double and/or integer values seperated by a ",".
The Point2D contains the most common operations which exists on a point, but also invlude convertion method to easy get the point as java.awt.Point or a java.awt.geom.Point2D.Double.

Constructor Example			Comments
Property<Point2D> A_PROPERTY = new Property<Point2D>("name", new Point2DPropertyType());			Creates Point2DPropertyType with no default value.
Property<Point2D> A_PROPERTY = new Property<Point2D>("name", new Point2DPropertyType(new Point2D(-3.5,999,22));			Creates Point2DPropertyType with a a default value .
Type of value(s)	Examples	Result	Comments
Valid	3,4	new Point2D(3,4)	Validate successfully.
Valid	-3.453E-23,99.88	new Point2D(-3.453E-23,99.88)	Validate successfully.
Invalid	cow	null	Validate will throw an exception. The resulting value is null.
Invalid	«empty string»	null
Invalid	«empty string after trim»	null
Invalid	555,33,44	null

Method Detail

getRestrictions

public List<String> getRestrictions()

Description copied from class: PropertyType

Gets a detailed description of the PropertyType with any constraints that might influence the validation.
This includes a description for the default value, if the default do not it self parse the validation of the type, the exception is appended to the description.

Specified by:

getRestrictions in class PropertyType<Point2D>

Returns:

the restrictions of the PropertyType as a list of strings.

validateValue

public Point2D validateValue(String propertyName,
                             String value)
                      throws PropertyException

Description copied from class: PropertyType

Converts the string representation of to a typed value.
Including validation of any restrictions the PropertyType might have.
See the individual property type class description for details on how it convert to a typed value.

IMPORTANT: This only validates the value not the constraints of the PropertyType, which is at this point assumed to be valid.

Specified by:

validateValue in class PropertyType<Point2D>

Parameters:

propertyName - the name of the property used for logging purposes. To uniquely identify the Property with validation issues.

value - the string representation of the property

Returns:

the typed converted value.

Throws:

PropertyException - if the conversion failed.

toString

public String toString(String propertyName,
                       Point2D t)
                throws PropertyException

Description copied from class: PropertyType

Converts a typed to the string representation. This must be associative, so the string generate here will successful validate. This is enforced, so the converted string is sub sequencetially validate with the validate method. In some of the property sub types, this method is overridden to ensure above rule.

Overrides:

toString in class PropertyType<Point2D>

Parameters:

propertyName - the name of the property used for logging purposes.

t - the type T.

Returns:

The string representation of the type.

Throws:

PropertyException - if conversion failed in validation.
