public class Range extends Input
The type of the values (which will be derived from the value restrictions)
must be a subclass of either
ComparableIndividual (only those with
ordinal characteristics that do not return null in the implementation of
related methods) or a number (double, float, int or long). However, numbers
can be used only if the value restrictions are specified with the help of
BoundedValueRestriction. Other classes
that implement Comparable are not supported because there
is no straightforward solution to determine the next or previous values based
on a step.

a positive number (defaults to 1) for determining a next or previous
value relative to a given value.

| Modifier and Type | Method and Description |
|---|---|
int |
getMaxLength()
Overrides
FormControl.getMaxLength() by returning always -1,
because no standard string representation of a range control exists. |
Comparable |
getMaxValue() |
Comparable |
getMinValue() |
int |
getRangeLength()
Using the value of
PROP_STEP, returns the number of steps
between the min and max values. |
Number |
getStep() |
int |
getStepsValue()
Using the current value stored in this range control and the value of
PROP_STEP, tries to calculate the number of steps that separate
the current value and minimun value. |
boolean |
setProperty(String propURI,
Object value)
For usage by de-serializers.
|
boolean |
setStep(Number step) |
Comparable |
shiftValue(int numberOfSteps)
Using the current value stored in this range control and the value of
PROP_STEP, tries to calculate a new value that is then stored to
substitute the current value. |
Comparable |
stepValue(int numberOfStepsFormMin)
Using the current value stored in this range control and the value of
PROP_STEP, tries to calculate a new value form the steps from
min value. |

public Range(Group parent, Label label, PropertyPath ref, MergedRestriction valueRestriction, Object initialValue)
parent - The mandatory parent group as the direct container of this
input field. See FormControl.PROP_PARENT_CONTROL.label - The optional Label to be associated with this input
field. See FormControl.PROP_CONTROL_LABEL.ref - See FormControl.PROP_REFERENCED_PPATH; mandatory.valueRestriction - See FormControl.PROP_VALUE_RESTRICTION; optional.initialValue - The optional initial value to be stored in form data under the
path given for the above ref parameter.public int getMaxLength()
FormControl.getMaxLength() by returning always -1,
because no standard string representation of a range control exists.getMaxLength in class FormControlpublic Comparable getMaxValue()
public Comparable getMinValue()
public Comparable shiftValue(int numberOfSteps)
PROP_STEP, tries to calculate a new value that is then stored to
substitute the current value.numberOfSteps - Number of sttp. Will be multiplied by the value of
PROP_STEP in oer to calculate theamount o requied
shift. If positive, the shift will be towards max value;
otherwise towards min value.public int getStepsValue()
PROP_STEP, tries to calculate the number of steps that separate
the current value and minimun value.getRangeLength()).getRangeLength(),
stepValue(int)public Comparable stepValue(int numberOfStepsFormMin)
PROP_STEP, tries to calculate a new value form the steps from
min value. Helper method for UIHandlers.numberOfStepsFormMin - Number of steps. Will be multiplied by the value of
PROP_STEP in oder to calculate the new amount, it
must be between 0 and getRangeLength() -1.getRangeLength(),
