Append a symbol value onto a mongo.bson.buffer.
1 | mongo.bson.buffer.append.symbol(buf, name, value)
|
buf |
(mongo.bson.buffer) The buffer object to which to append. |
name |
(string) The name (key) of the field appended to the buffer. |
value |
(string) The value of the symbol. Note that the value may simply be a string representing the symbol's value and not necessarily a mongo.symbol object. |
BSON has a special field type to indicate a symbol. This function appends such an indicator as the type of a field with its value.
TRUE if successful; otherwise, FALSE if an error occured appending the data.

mongo.bson.buffer.append.symbol(buf, "A", "Alpha")
b <- mongo.bson.from.buffer(buf)
# The above produces a BSON object of the form { "A" : (SYMBOL) "Alpha" }
# The same result can be produced by the following code:
buf <- mongo.bson.buffer.create()
sym <- mongo.symbol.create("Alpha")
mongo.bson.buffer.append(buf, "A", sym)
b <- mongo.bson.from.buffer(buf)
