Interface TokensManagement

public interface TokensManagement

Tokens API allows for manipulating generic tokens. Token is a piece of information which is:

• bound to an entity
• has unique identifier
• has type (e.g. OAuth access token)
• can have expiration time, when it is removed
• can contain additional, type specific data

Tokens are used by both engine and endpoint extension modules.

As this is a low level interface it allows for external transaction steering. All methods will join an existing transaction if it is present.

Method Details

addToken

void addToken(String type,
 String value,
 EntityParam owner,
 byte[] contents,
 Date created,
 Date expires)
       throws IllegalIdentityValueException,
IllegalTypeException

Adds a new token

Parameters:

type - type or category of the token

created - creation timestamp. It is guaranteed to be stored with second precision, though implementation might also store the full time.

expires - precision as in created case.

Throws:

IllegalIdentityValueException

IllegalTypeException

addToken

void addToken(String type,
 String value,
 byte[] contents,
 Date created,
 Date expires)
       throws IllegalTypeException

Adds a new token without owner

Parameters:

type - type or category of the token

created - creation timestamp. It is guaranteed to be stored with second precision, though implementation might also store the full time.

expires - precision as in created case.

Throws:

IllegalTypeException

removeToken

void removeToken(String type,
 String value)

Removes the token

updateToken

void updateToken(String type,
 String value,
 Date expires,
 byte[] contents)

Update the token. Only contents and expiration time can be updated - the type and value are used to look up a token for update.

Parameters:

expires - if null -> leave unchanged

contents - if null -> leave unchanged

getTokenById

pl.edu.icm.unity.base.token.Token getTokenById(String type,
 String value)

Returns a specified token

getOwnedTokens

List<pl.edu.icm.unity.base.token.Token> getOwnedTokens(String type,
 EntityParam entity)
                                                throws IllegalIdentityValueException,
IllegalTypeException

Returns all tokens of the entity

Throws:

IllegalIdentityValueException

IllegalTypeException

getAllTokens

List<pl.edu.icm.unity.base.token.Token> getAllTokens(String type)

Returns:

all tokens of a given type

getAllTokens

List<pl.edu.icm.unity.base.token.Token> getAllTokens()

Returns:

all tokens

addTokenExpirationListener

void addTokenExpirationListener(TokensManagement.TokenExpirationListener listener,
 String type)

Adds a new listenr which is notified about expired tokens of a specified type
