Method Detail

values

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

Returns:

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

valueOf

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

getValue

public byte getValue()

Returns the byte value of the enumerations value

Returns:

byte representation

getReadTier

public static ReadTier getReadTier(byte value)

Get ReadTier by byte value.

Parameters:

value - byte representation of ReadTier.

Returns:

ReadTier instance or null.

Throws:

java.lang.IllegalArgumentException - if an invalid value is provided.
