mongo.timestamp: The mongo.timestamp class

Description

Objects of class "mongo.timestamp" are an extension of the POSIXct class. They have their increment value stored in the "increment" attribute of the object.

Details

See http://www.mongodb.org/display/DOCS/Timestamp+Data+Type

mongo.timestamp objects have "mongo.timestamp", "POSIXct" & "POSIXt" as their class so that mongo.bson.buffer.append() may detect them and append the appropriate BSON code-typed value to a buffer.

These mongo.timestamp values may also be present in a list and will be handled properly by mongo.bson.buffer.append.list() and mongo.bson.from.list().

Examples

mongo <- mongo.create()
if (mongo.is.connected(mongo)) {
    buf <- mongo.bson.buffer.create()
    # special Null timestamp -- automatically filled in
    # if one of first two fields in a record
    ts <- mongo.timestamp.create(0,0)
    mongo.bson.buffer.append(buf, "InsertTime", ts)
    mongo.bson.buffer.append(buf, "name", "Joe")
    b <- mongo.bson.from.buffer(buf)
    mongo.insert(mongo, "test.people", b)

    # create using a POSIXlt
    ts <- mongo.timestamp.create(strptime("05-12-2012",
        "%m-%d-%Y"), increment=1)
}
