Enum LittleEndianByteArray.UnsafeByteArray
- java.lang.Object
-
- java.lang.Enum<LittleEndianByteArray.UnsafeByteArray>
-
- com.google.common.hash.LittleEndianByteArray.UnsafeByteArray
-
- All Implemented Interfaces:
LittleEndianByteArray.LittleEndianBytes
,java.io.Serializable
,java.lang.Comparable<LittleEndianByteArray.UnsafeByteArray>
- Enclosing class:
- LittleEndianByteArray
private static enum LittleEndianByteArray.UnsafeByteArray extends java.lang.Enum<LittleEndianByteArray.UnsafeByteArray> implements LittleEndianByteArray.LittleEndianBytes
The only reference to Unsafe is in this nested class. We set things up so that if Unsafe.theUnsafe is inaccessible, the attempt to load the nested class fails, and the outer class's static initializer can fall back on a non-Unsafe version.

values
public static LittleEndianByteArray.UnsafeByteArray[] 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 (LittleEndianByteArray.UnsafeByteArray c : LittleEndianByteArray.UnsafeByteArray.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static LittleEndianByteArray.UnsafeByteArray valueOf(java.lang.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:
java.lang.IllegalArgumentException
- if this enum type has no constant with the specified namejava.lang.NullPointerException
- if the argument is null
-
getUnsafe
private static sun.misc.Unsafe getUnsafe()
Returns a sun.misc.Unsafe. Suitable for use in a 3rd party package. Replace with a simple call to Unsafe.getUnsafe when integrating into a jdk.- Returns:
- a sun.misc.Unsafe instance if successful
