All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Options.ChecksumCombineMode>

Enclosing class:

Options

public static enum Options.ChecksumCombineMode
extends java.lang.Enum<Options.ChecksumCombineMode>

Enum for indicating what mode to use when combining chunk and block checksums to define an aggregate FileChecksum. This should be considered a client-side runtime option rather than a persistent property of any stored metadata, which is why this is not part of ChecksumOpt, which deals with properties of files at rest.

Method Detail

values

public static Options.ChecksumCombineMode[] 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 (Options.ChecksumCombineMode c : Options.ChecksumCombineMode.values())
    System.out.println(c);

Returns:

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

valueOf

public static Options.ChecksumCombineMode 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 name

java.lang.NullPointerException - if the argument is null
