Member Function Documentation

void LocalProperty::addPropertyListener (  PropertyListener *  pl, bool  refresh = true )  [virtual]

Add a new property listener to this property. This listener's methods will be called when the property is modified. See also: PropertyListener Parameters: pl  The new property listener. If it is also a RefCounted object, references will be acquired correctly. Reimplemented from Property. Definition at line 343 of file localproperty.cc. Referenced by startListeningHandler().

void LocalProperty::getLengthHandler (  Message *  m  )  [protected]

Definition at line 137 of file localproperty.cc. Referenced by LocalProperty().

const deque< PropertyAccessControl * > & LocalProperty::getPropertyAccessControls (   )  [virtual]

Returns: the current access control policy list. See also: insertAccessControl Definition at line 405 of file localproperty.cc.

virtual const string LocalProperty::getSource (   )  [inline, virtual]

Definition at line 538 of file property.hh.

virtual void LocalProperty::initialize (   )  [inline, virtual]

Set a default access control policy. Reimplemented in ExtrapolatedLocalProperty. Definition at line 541 of file property.hh.

Definition at line 357 of file localproperty.cc. Referenced by COD::readCOD().

void LocalProperty::insertPropertyAccessControl (  int  pos, const string &  policyname )  [virtual]

Add a named policy. See also: VobjectAccessControl::getPolicy VobjectAccessControl::addPolicy Definition at line 371 of file localproperty.cc.

void LocalProperty::insertPropertyAccessControl (  int  pos, PropertyAccessControl *  ac )  [virtual]

Insert a new policy into the access policy list. The access policy list is traversed from beginning to end, calling each access control policy in order until either a policy returns false (deny) or the end of the list is reached. If access is denied, list traversal immediately stops and the requested action is denied. If the end of the list is reached without a denial, the requested action is permitted. Parameters: pos  The position to be inserted into. As with most other parts of VOS, a positive value counts from the beginning and a negative value counts from the end. In particular, a position of 0 will insert at the head of the list, making it the the first policy to be consulted. A position of -1 will insert at the end of the list, making it the last policy to be consulted. ac  the access control policy Definition at line 365 of file localproperty.cc.

Remove all policies matching this name. See also: VobjectAccessControl::addPolicy VobjectAccessControl::getPolicy Definition at line 395 of file localproperty.cc.

void LocalProperty::removePropertyAccessControl (  PropertyAccessControl *  m  )  [virtual]

void LocalProperty::replace (  const string &  newdata, const string &  newtype = "?" )  [virtual]

Completely change the value and type of data stored in this property. Parameters: newdata  New data. newtype  The type of the new datatype. If no type identifier was supplied, the previous one is kept. NOTE: the initial datatype (set by the constructor) is "?" which is (or should be) an invalid value for any application. Reimplemented from Property. Reimplemented in BufferedLocalProperty, DBProperty, ExtrapolatedLocalProperty, and FileProperty. Definition at line 132 of file localproperty.cc.
