Method Detail

setPermission

void setPermission(int bitmask,
                   boolean value)
Set or reset all the permission bits from the given bitmask.

Parameters:
bitmask - the permission(s) bits to modify
value - whether to turn on off of the permission(s) Example: setPermission(PERM_USER_WRITE | PERM_GROUP_WRITE, true);

getPermission

boolean getPermission(int bitmask)
Test if any of the permission bits from the bitmask are set.

Parameters:
bitmask - the permission(s) to check for
Returns:
true if one of the permission bits is set Example: getPermission(PERM_USER_WRITE | PERM_GROUP_WRITE)

getPermissionBits

int getPermissionBits()
Get the set of permission bits.

Returns:
set of permission bits

setPermissionBits

void setPermissionBits(int bits)
Set the permission bits

Parameters:
bits - the set of permission bits

toAlphaString

String toAlphaString()
return permissions in rwxrwxrwx form


getUserOwner

String getUserOwner()
returns the user owner of the file

Returns:
the user owner

getGroupOwner

String getGroupOwner()
returns the group owner of the file

Returns:
the group owner

setUserOwner

void setUserOwner(
String user)
Sets the user owner attribute

Parameters:
user - the user owner attribute

setGroupOwner

void setGroupOwner(
String group)
Sets the group owner attribute

Parameters:
group - the group owner attribute

clone

Object clone()
             throws 
CloneNotSupportedException
Creates and returns a copy of this object, as specified by the Object.clone() contract. Each implementer of the IHostFilePermission API must properly implement this method and implement the Cloneable interface.

Returns:
the cloned object
Throws:
CloneNotSupportedException - if an instance cannot be cloned for any reason, e.g. because its state contains complex objects that cannot be cloned.
