# Enum Class Priority

java.lang.Object
java.lang.Enum<Priority>
javafx.scene.layout.Priority

All Implemented Interfaces:
  `Serializable`, `Comparable<Priority>`, `Constable`

public enum Priority extends Enum<Priority>
Enumeration used to determine the grow (or shrink) priority of a given node's layout area when its region has more (or less) space available and multiple nodes are competing for that space.

Since:
  JavaFX 2.0

  Enum Constants
  Enum Constant
  Description
  `ALWAYS`
  Layout area will always try to grow (or shrink), sharing the increase (or decrease) in space with other layout areas that have a grow (or shrink) of ALWAYS.
  `NEVER`
  Layout area will never grow (or shrink) when there is an increase (or decrease) in space available in the region.
  `SOMETIMES`
  If there are no other layout areas with grow (or shrink) set to ALWAYS or those layout areas didn't absorb all of the increased (or decreased) space, then will share the increase (or decrease) in space with other layout area's of SOMETIMES.

  - ### ALWAYS

    public static final Priority ALWAYS
    Layout area will always try to grow (or shrink), sharing the increase (or decrease) in space with other layout areas that have a grow (or shrink) of ALWAYS.

  - ### SOMETIMES

    public static final Priority SOMETIMES
    If there are no other layout areas with grow (or shrink) set to ALWAYS or those layout areas didn't absorb all of the increased (or decreased) space, then will share the increase (or decrease) in space with other layout area's of SOMETIMES.

  - ### NEVER

    public static final Priority NEVER
    Layout area will never grow (or shrink) when there is an increase (or decrease) in space available in the region.

- ## Method Details

  - ### values

    public static Priority[] values()
    Returns an array containing the constants of this enum class, in the order they are declared.
    Returns:
      an array containing the constants of this enum class, in the order they are declared

  - ### valueOf

    public static Priority valueOf(String name)
    Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
    Parameters:
      `name` - the name of the enum constant to be returned.
    Returns:
      the enum constant with the specified name
    Throws:
      `IllegalArgumentException` - if this enum class has no constant with the specified name
      `NullPointerException` - if the argument is null

  - ### max

    public static Priority max(Priority a, Priority b)
    Convenience method for returning the higher of two priorities.
    Parameters:
      `a` - first priority
      `b` - second priority
    Returns:
      the highest of the two priorities

  - ### min

    public static Priority min(Priority a, Priority b)
    Convenience method for returning the lower of two priorities.
    Parameters:
      `a` - first priority
      `b` - second priority
    Returns:
      the lower of the two priorities
