javax.smartcardio.CardPermission

All Implemented Interfaces:

Serializable, Guard

public class CardPermission
extends Permission

A permission for Smart Card operations. A CardPermission consists of the name of the card terminal the permission applies to and a set of actions that are valid for that terminal.

A CardPermission with a name of * applies to all card terminals. The actions string is a comma separated list of the actions listed below, or * to signify "all actions."

Individual actions are:

connect

connect to a card using CardTerminal.connect()

reset

reset the card using Card.disconnect(true)

exclusive

establish exclusive access to a card using Card.beginExclusive() and endExclusive()

transmitControl

transmit a control command using Card.transmitControlCommand()

getBasicChannel

obtain the basic logical channel using Card.getBasicChannel()

openLogicalChannel

open a new logical channel using Card.openLogicalChannel()

Constructor Detail

CardPermission

public CardPermission(String terminalName,
                      String actions)

Constructs a new CardPermission with the specified actions. terminalName is the name of a CardTerminal or * if this permission applies to all terminals. actions contains a comma-separated list of the individual actions or * to signify all actions. For more information, see the documentation at the top of this class.

Parameters:

terminalName - the name of the card terminal, or *

actions - the action string (or null if the set of permitted actions is empty)

Throws:

NullPointerException - if terminalName is null

IllegalArgumentException - if actions is an invalid actions specification

Method Detail

getActions

public String getActions()

Returns the canonical string representation of the actions. It is * to signify all actions defined by this class or the string concatenation of the comma-separated, lexicographically sorted list of individual actions.

Specified by:

getActions in class Permission

Returns:

the canonical string representation of the actions.

implies

public boolean implies(Permission permission)

Checks if this CardPermission object implies the specified permission. That is the case, if and only if

• permission is an instance of CardPermission,

• permission's actions are a proper subset of this object's actions, and

• this object's getName() method is either * or equal to permission's name.

Specified by:

implies in class Permission

Parameters:

permission - the permission to check against

Returns:

true if and only if this CardPermission object implies the specified permission.

equals

public boolean equals(Object obj)

Compares the specified object with this CardPermission for equality. This CardPermission is equal to another Object object, if and only if

• object is an instance of CardPermission,

• this.getName() is equal to ((CardPermission)object).getName(), and

• this.getActions() is equal to ((CardPermission)object).getActions().

Specified by:

equals in class Permission

Parameters:

obj - the object to be compared for equality with this CardPermission

Returns:

true if and only if the specified object is equal to this CardPermission

Object.hashCode(), HashMap

hashCode

public int hashCode()

Returns the hash code value for this CardPermission object.

Specified by:

hashCode in class Permission

Returns:

the hash code value for this CardPermission object.
