Method Detail

buildFromMask

public static Permission buildFromMask(int mask)

Dynamically creates a CumulativePermission or BasePermission representing the active bits in the passed mask.

Parameters:

mask - to build

Returns:

a Permission representing the requested object

buildFromMask

public static Permission[] buildFromMask(int[] masks)

buildFromName

public static Permission buildFromName(String name)

buildFromName

public static Permission[] buildFromName(String[] names)

equals

public boolean equals(Object arg0)

Overrides:

equals in class Object

getMask

public int getMask()

Description copied from interface: Permission

Returns the bits that represents the permission.

Specified by:

getMask in interface Permission

Returns:

the bits that represent the permission

getPattern

public String getPattern()

Description copied from interface: Permission

Returns a 32-character long bit pattern String representing this permission.

Implementations are free to format the pattern as they see fit, although under no circumstances may Permission.RESERVED_OFF or Permission.RESERVED_ON be used within the pattern. An exemption is in the case of Permission.RESERVED_OFF which is used to denote a bit that is off (clear). Implementations may also elect to use Permission.RESERVED_ON internally for computation purposes, although this method may not return any String containing Permission.RESERVED_ON.

The returned String must be 32 characters in length.

This method is only used for user interface and logging purposes. It is not used in any permission calculations. Therefore, duplication of characters within the output is permitted.

Specified by:

getPattern in interface Permission

Returns:

a 32-character bit pattern

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
