Hello Sergey, the ODATA 4.0 Filter parser is combined with the URI parser in order to parse the URI as a whole.
The filter expression tree itself is more or less the same as in ODATA 2.0 an can be accessed through an UriInfo object. The API for the URI parser is in package "org.apache.olingo.odata4.producer.api.uri" whereas the filter part is in "org.apache.olingo.odata4.producer.api.uri.queryoption.expression" Kind regards, Sven -----Original Message----- From: Bolz, Michael Sent: Mittwoch, 12.

At least the basic filter expressions (logic and arithmetic like Œeq¹, Œadd¹, Š). I think the functions have changed a little bit with naming and syntax. But I guess your question points more to the implementation in Olingo library for Odata 4. I think here we can give Sven a better answer. @Sven: Can you give an answer here?
