ATTRIBUTES
"looks_like_number"
$MongoDB::BSON::looks_like_number = 1;
$collection->insert({age => "4"}); # stores 4 as an int
If this is set, the driver will be more aggressive about converting
strings into numbers. Anything that Scalar::Util's looks_like_number
would approve as a number will be sent to MongoDB as its numeric value.
Defaults to 0 (for backwards compatibility).
If you do not set this, you may be using strings more often than you
intend to. See the MongoDB::DataTypes section for more info on the
behavior of strings vs. numbers.
char
$MongoDB::BSON::char = ":";
$collection->query({"x" => {":gt" => 4}});
Can be used to set a character other than "$" to use for special
operators.
Turn on/off UTF8 flag when return strings
# turn off utf8 flag on strings
$MongoDB::BSON::utf8_flag_on = 0;
Default is turn on, that compatible with version before 0.34.
If set to 0, will turn of utf8 flag on string attribute and return on
bytes mode, meant same as :
utf8::encode($str)
Currently MongoDB return string with utf8 flag, on character mode ,
some people wish to turn off utf8 flag and return string on byte mode,
it maybe help to display "pretty" strings.
NOTE:
If you turn off utf8 flag, the string length will compute as bytes,
and is_utf8 will return false.
Return boolean values as booleans instead of integers
$MongoDB::BSON::use_boolean = 1
By default, booleans are deserialized as integers. If you would like
them to be deserialized as "true" in boolean and "false" in boolean,
set $MongoDB::BSON::use_boolean to 1.
