Method Detail

values

public static EC2MetadataKeys[] 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 (EC2MetadataKeys c : EC2MetadataKeys.values())
    System.out.println(c);

Returns:

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

valueOf

public static EC2MetadataKeys 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

getName

public String getName()

Returns:

The name of key

getURL

public URL getURL(String prepend,
                  String append)
           throws MalformedURLException

The URL for metadata information. Override to apply prepend and append.

Parameters:

prepend - Building the URL endpoints

append - Region

Returns:

The URL for the Metadata information of specific name.

Throws:

MalformedURLException - If the URL is invalid

toString

public String toString()

Returns the name of this enum constant, as contained in the declaration. This method may be overridden, though it typically isn't necessary or desirable. An enum type should override this method when a more "programmer-friendly" string form exists.

Overrides:

toString in class Enum<EC2MetadataKeys>

Returns:

the name of this enum constant
