How to process the 'filter' from QueryInfo in odata4j

Question

My RESTful web service is passing my Producer some filter information in their request. For example their URL includes :- /ACCOUNT-LIST?$filter=Id eq '45012'

How do I process this in odata4j?

From the odata4j JavaDoc I can see that the filter is of type BoolCommonExpression, but can't see any documentation or examples on how I process this.

Also how do I process more than 1 filter option being passed?

Thanks

BoolCommonExpression is the base type of an expression hierarchy (including compound expressions).

You can do instanceof checks or use .visit(ExpressionVisitor) to handle each expression type differently.

Hope that helps,
