--------------------------------------
Summary: [RelJson] create a new public toRex method which can
override makeInputRef
Key: CALCITE-4996
URL: https://issues.apache.org/jira/browse/CALCITE-4996
Project: Calcite
Issue Type: Improvement
Components: core
Reporter: Marieke Gueye
In the case of our project, the environment that generates a JSON from a
RexNode and the environment that reads it are different. We need to "translate"
the inputs into their aliases in the new cluster.
This method will permit to give more freedom to the JSON RexNode parser if
needed.
```
/**
* Transforms a RexNode tree defined in a map (from a JSON) into a RexNode
* @param cluster: The optimization Environment
* @param o the map derived from a RexNode transformed into a JSON
* @param InputMapToRex is a BiFunction that transform the map representing
input references into RexNode.
* it has two parameters: the map of the references and the RexBuilder
* @return the RexNode
*/
public RexNode toRex(RelOptCluster cluster, Object o, BiFunction<Map,
RexBuilder, RexNode> InputMapToRex)
```
Make sure that `RexNode toRex(RelInput relInput, @PolyNull Object o) ` is still
working
