Method and device for hiding messages
View Patent ↗Based on user configuration, a main messaging user interface screen on a messaging device either presents a list of references to messages stored on the device based on a complete index of references to the stored messages or based on a filtered index of references to the stored messages. References to stored messages of a predetermined type are not maintained in the filtered index.
1. A method of presenting a user interface on a communication device on which device are stored a plurality of messages, said method comprising:
maintaining a master index of references to a plurality of message objects, said plurality of message objects including a plurality of received message objects, a plurality of sent message objects and a plurality of other message objects, where said other message objects are neither received message objects nor sent message objects;
receiving an indication of a filtering criterion, wherein said filtering criterion specifies that references to said sent message objects are to be omitted from said filtered index;
creating, based on said master index, a filtered index of references to a plurality of message objects that satisfy said filtering criterion, where said creating said filtered index includes:
selecting a given reference from said master index;
determining whether a given message object corresponding to said given reference satisfies said filtering criterion; and
if said given message object satisfies said filtering criterion, adding said given reference to said filtered index;
forming a display list based on said filtered index; and
presenting said display list.
2. The method of claim 1 wherein said determining whether said given message object satisfies said filtering criterion comprises:
sending a status query to said given message object;
receiving, from said given message object, a communication responsive to said status query; and
determining, from said communication, whether said given message object satisfies said filtering criterion.
3. The method of claim 2 wherein said communication includes a plurality of status bits and said determining whether said given message object satisfies said filtering criterion comprises determining a value for a given bit among said plurality of bits, where said given bit indicates whether said given message object is a sent message object.
4. A mobile communication device comprising:
memory for storing a plurality of message objects, said plurality of message objects including a plurality of received message objects, a plurality of sent message objects and a plurality of other message objects, where said other message objects are neither received message objects nor sent message objects;
a processor adapted to:
maintain a master index of references to said plurality of message objects;
receive an indication of a filtering criterion, wherein said filtering criterion specifies that references to said sent message objects are to be omitted from said filtered index;
create, based on said master index, a filtered index of references to a plurality of message objects that satisfy said filtering criterion, where said creating said filtered index includes:
selecting a given reference from said master index;
determining whether a given message object corresponding to said given reference satisfies said filtering criterion; and
if said given message object satisfies said filtering criterion, adding said given reference to said filtered index;
form a display list based on said filtered index; and
present said display list.
5. A non-transitory computer readable medium containing computer-executable instructions that, when performed by processor in a mobile communication device, cause said processor to:
maintain a master index of references to a plurality of message objects, said plurality of message objects including a plurality of received message objects, a plurality of sent message objects and a plurality of other message objects, where said other message objects are neither received message objects nor sent message objects;
receive an indication of a filtering criterion, wherein said filtering criterion specifies that references to said sent message objects are to be omitted from said filtered index;
create, based on said master index, a filtered index of references to a plurality of message objects that satisfy said filtering criterion, where said creating said filtered index includes:
selecting a given reference from said master index;
determining whether a given message object corresponding to said given reference satisfies said filtering criterion; and
if said given message object satisfies said filtering criterion, adding said given reference to said filtered index;
form a display list based on said filtered index; and
present said display list.
