CkoMessageSet

The number of message UIDs (or sequence numbers) in this message set.

If YES then the message set contains UIDs, otherwise it contains sequence numbers.

Indicate whether the last method call succeeded or failed. A value of YES indicates success, a value of NO indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:

• Any method that returns a string.
• Any method returning a Chilkat object, binary bytes, or a date/time.
• Any method returning a standard boolean status value where success = YES and failure = NO.
• Any method returning an integer where failure is defined by a return value less than zero.

Note: Methods that do not fit the above requirements will always set this property equal to YES. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

Returns YES if the msgId is contained in the message set.

Loads the message set from a compact-string representation. Here are some examples:

Returns the message ID of the Nth message in the set. (indexing begins at 0). Returns 0xFFFFFFFF if the index is out of range.

Inserts a message ID into the set. If the ID already exists, a duplicate is not inserted.

Loads the message set from a completed asynchronous task.

Returns YES for success, NO for failure.

Removes a message ID from the set.

Returns a string of comma-separated message IDs. (This is the non-compact string format.)

Returns nil on failure

Returns the set of message IDs represented as a compact string. Here are some examples:

Returns nil on failure
