Constructor Detail

AbstractPermission

protected AbstractPermission(String name)

Construct a new instance.

Parameters:

name - the permission name

Method Detail

implies

public final boolean implies(Permission permission)

Determine whether this permission implies another permission.

Specified by:

implies in interface PermissionVerifier

Specified by:

implies in class Permission

Parameters:

permission - the other permission

Returns:

true if this permission implies the other; false otherwise

implies

public abstract boolean implies(This permission)

Determine whether this permission implies another permission.

Parameters:

permission - the other permission

Returns:

true if this permission implies the other; false otherwise

equals

public final boolean equals(Object obj)

Determine whether this permission object is equal to another object.

Specified by:

equals in class Permission

Parameters:

obj - the object to compare to

Returns:

true if the object is a permission equal to this one; false otherwise

equals

public abstract boolean equals(This other)

Determine whether this permission object is equal to another object of this permission type.

Parameters:

other - the permission to compare to

Returns:

true if the object is a permission equal to this one; false otherwise

hashCode

public abstract int hashCode()

Get the hash code of this permission. The result must be consistent with the defined equals(AbstractPermission) result.

Specified by:

hashCode in class Permission

Returns:

the hash code of this permission

getActions

public String getActions()

Get the actions string. The default implementation always returns an empty string.

Specified by:

getActions in class Permission

Returns:

the actions string (not null)

newPermissionCollection

public AbstractPermissionCollection newPermissionCollection()

Get an empty permission collection which is capable of holding instances of this permission type.

The default implementation returns a SimplePermissionCollection.

Overrides:

newPermissionCollection in class Permission

Returns:

the permission collection to use

requireEmptyActions

protected static void requireEmptyActions(String actions)
                                   throws IllegalArgumentException

Check to ensure that the given action string is empty or null; otherwise, throw an exception.

Parameters:

actions - the actions string

Throws:

IllegalArgumentException - if the actions string is not empty
