Package net.pincette.mongo

Class Match

java.lang.Object
net.pincette.mongo.Match
public class Match extends Object
You can match JSON objects with MongoDB queries using this class. The following operators are not supported: $jsonSchema, $text, $where and the geospatial operators. The operator $expr should contain only expressions which yield a boolean or aggregation expressions. The operator $all doesn't work with the $elemMatch operator.

If you wrap an expression in the $trace operator then tracing will be done for it in the logger "net.pincette.mongo.expressions" at level INFO.
