Constructor Detail

Authorizations

public Authorizations(Collection<byte[]> authorizations)

A convenience constructor that accepts a collection of string authorizations that have each already been encoded as UTF-8 bytes.

Authorizations(String...)

Authorizations

public Authorizations(byte[] authorizations)

Constructs an authorizations object a serialized form. This is NOT a constructor for a set of authorizations of size one.

Parameters:

authorizations - a serialized authorizations string produced by getAuthorizationsArray() or serialize() (converted to UTF-8 bytes)

Authorizations

public Authorizations()

Constructs an empty set of authorizations.

Authorizations(String...)

Authorizations

public Authorizations(String... authorizations)

Constructs an authorizations object from a set of human-readable authorizations.

Parameters:

authorizations - array of authorizations

Method Detail

getAuthorizationsArray

public byte[] getAuthorizationsArray()

Retrieve a serialized form of the underlying set of authorizations.

See Also:

Authorizations(byte[])

getAuthorizations
