Improved BSONObj Builder Macros
BSONS

A macro to build a BSONObj of custom initial buffer size from a stream to reduce memory allocation times.

e.g.,

BSONS(32, "name" << "joe" << "age" << 33 )

with auto-generated object id:

BSONS(64, GENOID << "name" << "joe" << "age" << 33 )

when size is 64, it is the same as:

BSON(GENOID << "name" << "joe" << "age" << 33 )

The labels GT, GTE, LT, LTE, NE can be helpful for stream-oriented construction of a BSONObj, particularly when assembling a Query. For example,

BSONS(96, "a" << GT << 23.4 << NE << 30 << "b" << 2 ) produces the object { a: { $gt: 23.4, $ne: 30 }, b: 2 }.
QUERYS

QUERY's custom initsize version.
BSONS_ARRAY

Use BSONS_ARRAY macro like BSONS macro, but without keys

BSONArray arr = BSONS_ARRAY(128, "hello" << 1 <<
        BSON("foo" << BSONS_ARRAY(32, "bar" << "baz" << "qux" ) ) );
Debug Helpers
SHOW_BSON_BOB Print bson::bob object content in DEBUG mode.
SHOW_BSON_BO Print bson::bo object content in DEBUG mode.
SHOW_BSON_BE Print bson::be object content in DEBUG mode.
SHOW_MONGODB_LASTERR Print a mongodb connection's last error in DEBUG mode.
