BuiltInMetadata.AllPredicates (Apache Calcite API)

All Known Subinterfaces:

BuiltInMetadata.All

Enclosing class:

BuiltInMetadata
```
public static interface BuiltInMetadata.AllPredicates
extends Metadata
```
Metadata about the predicates that hold in the rows emitted from a relational expression.
The difference with respect to BuiltInMetadata.Predicates provider is that this provider tries to extract ALL predicates even if they are not applied on the output expressions of the relational expression; we rely on RexTableInputRef to reference origin columns in TableScan for the result predicates.
