    • HEAP

      public static final MemoryType HEAP
      Heap memory type.

      The Java virtual machine has a heap that is the runtime data area from which memory for all class instances and arrays are allocated.

    • NON_HEAP

      public static final MemoryType NON_HEAP
      Non-heap memory type.

      The Java virtual machine manages memory other than the heap (referred as non-heap memory). The non-heap memory includes the method area and memory required for the internal processing or optimization for the Java virtual machine. It stores per-class structures such as a runtime constant pool, field and method data, and the code for methods and constructors.

  • Method Details

    • values

      public static MemoryType[] 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 MemoryType 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

    • toString

      public String toString()
      Returns the string representation of this MemoryType.
      Overrides:
      toString in class Enum<MemoryType>
      Returns:
      the string representation of this MemoryType.
