Details

Public Constructors

public Permission(String name)

Constructs a new instance of this class with its name set to the argument.

Parameters

name String the name of the permission.

Public Methods

public void checkGuard(Object obj)

public abstract boolean equals(Object obj)

Compares the argument to the receiver, and returns true if they represent the same object using a class specific comparison. The implementation in Object returns true only if the argument is the exact same object as the receiver (==).

Parameters

obj Object the object to compare with this object.

Returns

  • boolean true if the object is the same as this object false if it is different from this object.

public abstract String getActions()

Returns the actions associated with the receiver. Subclasses should return their actions in canonical form. If no actions are associated with the receiver, the empty string should be returned.

Returns

  • String the receiver's actions.

public final String getName()

Returns the name of the receiver.

Returns

  • String the receiver's name.

public abstract int hashCode()

Returns an integer hash code for the receiver. Any two objects which answer true when passed to .equals must answer the same value for this method.

Returns

  • int the receiver's hash.

See Also

public abstract boolean implies(Permission permission)

Indicates whether the argument permission is implied by the receiver.

Parameters

permission Permission the permission to check.

Returns

  • boolean true if the argument permission is implied by the receiver, and false if it is not.

public PermissionCollection newPermissionCollection()

Returns a new PermissionCollection for holding permissions of this class. Answer null if any permission collection can be used.

Returns

  • PermissionCollection or null a suitable permission collection for instances of the class of the receiver.

public String toString()

Returns a string containing a concise, human-readable description of the receiver.

Returns

  • String a printable representation for the receiver.
