Method Detail

values

public static Bytes.LexicographicalComparerHolder.UnsafeComparer[] 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 (Bytes.LexicographicalComparerHolder.UnsafeComparer c : Bytes.LexicographicalComparerHolder.UnsafeComparer.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Bytes.LexicographicalComparerHolder.UnsafeComparer 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

compareTo

public int compareTo(byte[] buffer1,
                     int offset1,
                     int length1,
                     byte[] buffer2,
                     int offset2,
                     int length2)

Lexicographically compare two arrays.

Specified by:

compareTo in interface Bytes.Comparer<byte[]>

Parameters:

buffer1 - left operand

buffer2 - right operand

offset1 - Where to start comparing in the left buffer

offset2 - Where to start comparing in the right buffer

length1 - How much to compare from the left buffer

length2 - How much to compare from the right buffer

Returns:

0 if equal, < 0 if left is less than right, etc.
