Append an logical (boolean) or vector of logical values onto a mongo.bson.buffer.

|
buf |
(mongo.bson.buffer) The buffer object to which to append. |
name |
(string) The name (key) of the field appended to the buffer. |
value |
(logical vector) the booleans(s) to append to the buffer. If value has a If value has a names attribute, a subobject is appended and the subfields are given the indicated names. Otherwise, if more than one element is present in value, the booleans are appended as a subarray. In the last case, a single as.boolean is appended as the value of the field. |
TRUE if successful; otherwise, FALSE if an error occured appending the data.
