Package org.springframework.data.mongodb

Class BindableMongoExpression

java.lang.Object

org.springframework.data.mongodb.BindableMongoExpression

All Implemented Interfaces:

MongoExpression

public class BindableMongoExpression
extends Object
implements MongoExpression

A MongoExpression using the ParameterBindingDocumentCodec for parsing a raw (json) expression. The expression will be wrapped within { ... } if necessary. The actual parsing and parameter binding of placeholders like ?0 is delayed upon first call on the the target Document via toDocument().

 $toUpper : $name                -> { '$toUpper' : '$name' }

 { '$toUpper' : '$name' }        -> { '$toUpper' : '$name' }

 { '$toUpper' : '?0' }, "$name"  -> { '$toUpper' : '$name' }
 

Some types might require a special Codec. If so, make sure to provide a CodecRegistry containing the required codec via withCodecRegistry(CodecRegistry).
