Runtime type of an interpreted value, carrying its JVM slot category.

Enum Constant Summary

Enum Constants
Enum Constant	Description
`DOUBLE`	A 64-bit floating point value occupying two slots.
`FLOAT`	A 32-bit floating point value occupying one slot.
`INT`	A 32-bit signed integer occupying one slot.
`LONG`	A 64-bit signed integer occupying two slots.
`NULL`	The null reference occupying one slot, tagged apart from `REFERENCE` so an absent instance needs no heap object.
`REFERENCE`	A non-null pointer to an object or array on the interpreter heap, occupying one slot.
`RETURN_ADDRESS`	A jsr return address occupying one slot; produced only by the legacy subroutine opcodes.

  - REFERENCE
```
public static final ValueTag REFERENCE
```
    A non-null pointer to an object or array on the interpreter heap, occupying one slot.
  - NULL
```
public static final ValueTag NULL
```
    The null reference occupying one slot, tagged apart from REFERENCE so an absent instance needs no heap object.

- Method Detail
  - values
```
public static ValueTag[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (ValueTag c : ValueTag.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static ValueTag valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - getCategory
```
public int getCategory()
```
    Returns:
    
    the category
  - isWide
```
public boolean isWide()
```
    Returns:
    
    true for the category 2 types long and double, which occupy two slots
