Method Detail

values

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

Returns:

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

valueOf

public static LockClientUtils 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

millisecondTime

public long millisecondTime()

Calls System.nanoTime() and converts it to milliseconds. This is used by the lock client, since the lock client uses milliseconds as its base unit instead of nanoseconds.

Returns:

the current time in milliseconds, but not since epoch. It is only useful for elapsed time, not absolute time.
