MessageSet Node.js Reference Documentation

MessageSet

Current Version: 9.5.0.73

Represents a collection of email message sequence numbers or UIDs on an IMAP server.

Object Creation

var obj = new chilkat.MessageSet();

Properties

Count
Count
· integer, read-only

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

top
HasUids
HasUids
· boolean

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

top
LastMethodSuccess
LastMethodSuccess
· boolean

Indicate whether the last method call succeeded or failed. A value of true indicates success, a value of false 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 = true and failure = false.
  • 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 true. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

· Returns a Boolean.
· str String

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

Non-Compact String

1,3:5,8:10

top
GetId
var retInt = GetId(index);
· Returns a Number.
· index Number

Returns the message ID of the Nth message in the set. (indexing begins at 0). Returns -1 if the index is out of range.

top
InsertId
InsertId(id);
· Does not return anything (returns Undefined).

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

Returns null on failure

top
ToCompactString
var retStr = ToCompactString();
· Returns a String.

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