Method Details

values

public static UserCodeData[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static UserCodeData valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null

getKey

public String getKey()

Returns:

the key with which this entry is represented.

getUserCodePairFrom

public static it.unibo.ds.chainvote.utils.Pair<String,String> getUserCodePairFrom(Map<String,byte[]> transientData)

Parameters:

transientData - the Map containing the transient data

Returns:

a 2-dimensional tuple where the first element is the user identifier and the second the one-time-code.

Throws:

org.hyperledger.fabric.shim.ChaincodeException - if the given map not contains both CODE and USER_ID entries.
