### Public constructors
`FontVariationAxis(String tagString, float styleValue)` Construct FontVariationAxis.

`boolean` | `equals(Object o)` Indicates whether some other object is "equal to" this one.
`static FontVariationAxis[]` | `fromFontVariationSettings(String settings)` Construct FontVariationAxis array from font variation settings.
`float` | `getStyleValue()` Returns the style value associated to the given axis for this font.
`String` | `getTag()` Returns the variable font axis tag associated to this axis.
`int` | `hashCode()` Returns a hash code value for the object.
`static String` | `toFontVariationSettings(FontVariationAxis[] axes)` Stringify the array of FontVariationAxis.
`String` | `toString()` Returns a valid font variation setting string for this object.

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

## Public constructors

### FontVariationAxis

    public FontVariationAxis (String tagString,
                    float styleValue)

Construct FontVariationAxis. The axis tag must contain four ASCII characters. Tag string that are longer or shorter than four characters, or contains characters outside of U+0020..U+007E are invalid.

Parameters
`tagString` | `String`: This value cannot be `null`.
`styleValue` | `float`

Throws
`IllegalArgumentException` | If given tag string is invalid.

## Public methods

### equals

    public boolean equals (Object o)

Indicates whether some other object is "equal to" this one.

The `equals` method implements an equivalence relation on non-null object references:

- It is reflexive: for any non-null reference value `x`, `x.equals(x)` should return `true`.
- It is symmetric: for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`.
- It is transitive: for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.
- It is consistent: for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified.
- For any non-null reference value `x`, `x.equals(null)` should return `false`.

The `equals` method for class `Object` implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values `x` and `y`, this method returns `true` if and only if `x` and `y` refer to the same object (`x == y` has the value `true`).

Note that it is generally necessary to override the `hashCode` method whenever this method is overridden, so as to maintain the general contract for the `hashCode` method, which states that equal objects must have equal hash codes.

Parameters
`o` | `Object`: This value may be `null`.

Returns
`boolean` | `true` if this object is the same as the obj argument; `false` otherwise.

### fromFontVariationSettings

    public static FontVariationAxis[] fromFontVariationSettings (String settings)

Construct FontVariationAxis array from font variation settings. The settings string is constructed from multiple pairs of axis tag and style values. The axis tag must contain four ASCII characters and must be wrapped with single quotes (U+0027) or double quotes (U+0022). Axis strings that are longer or shorter than four characters, or contain characters outside of U+0020..U+007E are invalid. If a specified axis name is not defined in the font, the settings will be ignored.

       FontVariationAxis.fromFontVariationSettings("'wdth' 1.0");
       FontVariationAxis.fromFontVariationSettings("'AX  ' 1.0, 'FB  ' 2.0");

Parameters
`settings` | `String`: font variation settings. This value may be `null`.

Returns
`FontVariationAxis[]` | FontVariationAxis[] the array of parsed font variation axis. `null` if settings has no font variation settings.

Throws
`IllegalArgumentException` | If given string is not a valid font variation settings format.

### getStyleValue

    public float getStyleValue ()

Returns the style value associated to the given axis for this font.

Returns
`float` |

### getTag

    public String getTag ()

Returns the variable font axis tag associated to this axis.

Returns
`String` |

### hashCode

    public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by `HashMap`.

The general contract of `hashCode` is:

- Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the `equals(Object)` method, then calling the `hashCode` method on each of the two objects must produce the same integer result.
- It is not required that if two objects are unequal according to the `equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class `Object` does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
`int` | a hash code value for this object.

### toFontVariationSettings

    public static String toFontVariationSettings (FontVariationAxis[] axes)

Stringify the array of FontVariationAxis.

Parameters
`axes` | `FontVariationAxis`: an array of FontVariationAxis. This value may be `null`.

Returns
`String` | String a valid font variation settings string. This value cannot be `null`.

### toString

    public String toString ()

Returns a valid font variation setting string for this object.

Returns
`String` | This value cannot be `null`.
