public static DoubleProperty getInstance(String value)

checkRange

public void checkRange(Range range)
                throws ValidationException

Description copied from class: Element

Determine if the element satisfies the given range constraint. This is used in the validation of the element. By default, this method with throw a ValidationException indicating that range checking of this element is not appropriate.

Overrides:

checkRange in class Element

Parameters:

range - Range to check Element against

Throws:

ValidationException - if the element cannot be compared to a range or if the element doesn't meet the range requirement

doubleValue

public double doubleValue()

Description copied from class: NumberProperty

All number classes must implement this method which is used to facilitate type conversion in mixed-type, arithmetic expressions.

Specified by:

doubleValue in class NumberProperty

Returns:

value of this number as a double

getValue

public Double getValue()

Description copied from class: Property

Return the value of this property as an Object. Subclasses may override this method to provide a more specific return type. Subclasses will have to call this method to obtain the value because the value itself is private.

Overrides:

getValue in class Property

Returns:

value of this property as an Object

getTypeAsString

public String getTypeAsString()

Description copied from class: Element

All Elements must return a string describing its type. This value used in the serialization to machine profiles.

Specified by:

getTypeAsString in class Element

Returns:

String representation of Element's type
