## de.jstacs.parameters.validation
Class NumberValidator<E extends Comparable<? extends Number>>

    java.lang.Object
      de.jstacs.parameters.validation.NumberValidator<E>

Type Parameters:
  `E` - the subclass of `Number` to be validated

All Implemented Interfaces:
  ParameterValidator, Storable, Cloneable

    public class NumberValidator<E extends Comparable<? extends Number>>

extends Object
implements ParameterValidator

Class that validates all subclasses of `Number` that implement `Comparable` (e.g. `Double, Long, Float`) for compliance with a specified lower and upper bound.

Author:
  Jan Grau

Constructor Summary
`NumberValidator(E lowerBound, E upperBound)` Constructs a `NumberValidator` for a given upper and lower bound.
`NumberValidator(StringBuffer representation)` The standard constructor for the interface `Storable`.

Method Summary
`boolean` | `checkValue(Object value)` Returns `true` if the value is valid and `false` otherwise.
`NumberValidator` | `clone()` This method returns a deep copy of the current instance.
`void` | `fromXML(StringBuffer representation)` Parses a `NumberValidator` from the XML representation as returned by `toXML()`.
`String` | `getErrorMessage()` Returns the error message if `ParameterValidator.checkValue(Object)` returned false.
`E` | `getLowerBound()` Returns the lower bound of the `NumberValidator`.
`String` | `toString()`
`StringBuffer` | `toXML()` This method returns an XML representation as `StringBuffer` of an instance of the implementing class.

Constructor Detail

### NumberValidator

    public NumberValidator(E lowerBound,
                           E upperBound)

  Constructs a `NumberValidator` for a given upper and lower bound.

  Parameters:
    `lowerBound` - the lower bound
    `upperBound` - the upper bound

### NumberValidator

    public NumberValidator(StringBuffer representation)
                    throws NonParsableException

  The standard constructor for the interface `Storable`. Constructs a `NumberValidator` out of a XML representation.

  Parameters:
    `representation` - the XML representation as `StringBuffer`
  Throws:
    `NonParsableException` - if the representation could not be parsed

Method Detail

### clone

    public NumberValidator clone()

  Description copied from interface: `ParameterValidator`
  This method returns a deep copy of the current instance.

  Specified by:
    `clone` in interface `ParameterValidator`
  Overrides:
    `clone` in class `Object`
  Returns:
    a deep copy of the current index
  See Also:
    `Cloneable`

### getLowerBound

    public E getLowerBound()

  Returns the lower bound of the `NumberValidator`.

  Returns:
    the lower bound of the `NumberValidator`

### getErrorMessage

    public String getErrorMessage()

  Description copied from interface: `ParameterValidator`
  Returns the error message if `ParameterValidator.checkValue(Object)` returned false.

  Specified by:
    `getErrorMessage` in interface `ParameterValidator`
  Returns:
    the error message

### checkValue

    public boolean checkValue(Object value)

  Description copied from interface: `ParameterValidator`
  Returns `true` if the value is valid and `false` otherwise.

  Specified by:
    `checkValue` in interface `ParameterValidator`
  Parameters:
    `value` - the `Object` to be checked
  Returns:
    if `value` is valid

### fromXML

    public void fromXML(StringBuffer representation)
                 throws NonParsableException

  Parses a `NumberValidator` from the XML representation as returned by `toXML()`.

  Parameters:
    `representation` - the XML representation
  Throws:
    `NonParsableException` - if the XML code could not be parsed

### toXML

    public StringBuffer toXML()

  Description copied from interface: `Storable`
  This method returns an XML representation as `StringBuffer` of an instance of the implementing class.

  Specified by:
    `toXML` in interface `Storable`
  Returns:
    the XML representation

### toString

    public String toString()

  Overrides:
    `toString` in class `Object`
