Range (Geotools modules 21.0 API)

Object
- Range<T>

Type Parameters:

T - The type of range elements, typically Date or some subclass of Number.

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

DateRange, NumberRange
```
public class Range<T extends Comparable<? super T>>
extends Object
implements Serializable
```
A range between a minimum and maximum comparable. The minimum/maximum may be included, excluded or unbounded. The later case is indicated by null values on one or both ends.
This class is a method compatible replacement for the Range class with the following differences:
- Unbounded ranges (i.e. null minimal or maximal values) are considered exclusive rather than inclusive, since an iteration over the values will never reach the infinite bound. This interpretation brings some simplification in implementation and usage (e.g. a loop over the values should not attempt to process the null value).
- subtract(org.geotools.util.Range<?>) returns an empty array if the whole range is subtracted.
The exact element class doesn't need to be known at compile time. Widening conversions are allowed as needed (subclasses like NumberRange do that). This class is weakly parameterized in order to allow this flexibility. If any constructor or method is invoked with an argument value of illegal class, then an IllegalArgumentException is thrown. The ClassCastException is thrown only in case of bug in the Range class or subclasses implementation.

  - getElementClass
```
public Class<T> getElementClass()
```
    Returns the class of elements in this range. The element class extends Comparable.
    
    Returns:
    
    The class of elements in this range.
    
    See Also:
    
    Range.getElementClass()
  - getMinValue
```
public T getMinValue()
```
    Returns the minimal value, or null if unbounded. If isMinIncluded is true, then the value is considered included in the set. Otherwise it is considered excluded.
    
    Returns:
    
    The minimal value.
    
    See Also:
    
    Range.getMinValue()
  - isMinIncluded
```
public boolean isMinIncluded()
```
    Indicates if getMinValue() is included in the range.
    
    Returns:
    
    true if the minimal value is inclusive.
    
    See Also:
    
    Range.isMinIncluded
  - getMaxValue
```
public T getMaxValue()
```
    Returns the maximal value, or null if unbounded. If isMaxIncluded is true, then the value is considered included in the set. Otherwise it is considered excluded.
    
    Returns:
    
    The maximal value.
    
    See Also:
    
    Range.getMaxValue()
  - isMaxIncluded

public boolean isMaxIncluded()
```
    Indicates if getMaxValue() is included in the range.

    See Also:
    
    Range.isMaxIncluded
  - isEmpty
```

    See Also:
    
    Range.isEmpty()
  - contains
```
public boolean contains(Comparable<?> value)
                 throws IllegalArgumentException
```
    Returns true if this range contains the given value. A range never contains the null value. This is consistent with the class javadoc stating that null minimum or maximum values are exclusive.
    
    Parameters:
    
    value - The value to check for inclusion in this range.
    
    Returns:
    
    true if the given value is included in this range.
    
    Throws:
    
    IllegalArgumentException - is the given value can not be converted to a valid type through widening conversion.
  - contains
```
public boolean contains(Range<?> range)
                 throws IllegalArgumentException
```
    Returns true if this range contains fully the given range.
    
    Parameters:
    
    range - The range to check for inclusion in this range.
    
    Returns:
    
    true if the given range is included in this range.
    
    Throws:
    
    IllegalArgumentException - is the given range can not be converted to a valid type through widening conversion.
  - intersects
```
public boolean intersects(Range<?> range)
                   throws IllegalArgumentException
```
    Returns true if this range intersects the given range.
    
    Parameters:
    
    range - The range to check for intersection with this range.
    
    Returns:
    
    true if the given range intersects this range.
    
    Throws:
    
    IllegalArgumentException - is the given range can not be converted to a valid type through widening conversion.
    
    See Also:
    
    Range.intersects(javax.media.jai.util.Range)
  - intersect
```
public Range<?> intersect(Range<?> range)
                   throws IllegalArgumentException
```
    Returns the intersection between this range and the provided range.
    
    Parameters:
    
    range - The range to intersect.
    
    Returns:
    
    The intersection of this range with the provided range.

public Range<?>[] subtract(Range<?> range)
                    throws IllegalArgumentException
```
    Returns the range of values that are in this range but not in the given range. This method returns an array of length 0, 1 or 2:
    - If the given range contains fully this range, returns an array of length 0.
    - If the given range is in the middle of this range, then the subtraction results in two disjoint ranges which will be returned as two elements in the array.
    - Otherwise returns an array of length 1.
    Parameters:
    
    range - The range to substract.
    
    Returns:
    
    This range without the given range.
    
    Throws:

    Returns a hash code value for this range.
