Detailed Description
template<typename B>
class iceberg::Unbound< B >
class iceberg::Unbound< B >
Interface for unbound expressions that need schema binding.
Unbound expressions contain string-based references that must be resolved against a concrete schema to produce bound expressions that can be evaluated.
- Template Parameters
-
B The bound type this term produces when binding is successful
Member Function Documentation
◆ Bind()
template<typename B >
|
pure virtual |
Bind this expression to a concrete schema.
- Parameters
-
schema The schema to bind against case_sensitive Whether field name matching should be case sensitive
- Returns
- A bound expression or an error if binding fails
Implemented in iceberg::UnboundAggregateImpl< B >, iceberg::UnboundPredicateImpl< B >, iceberg::NamedReference, iceberg::UnboundTransform, and iceberg::UnboundPredicate.
◆ reference()
template<typename B >
|
pure virtual |
Returns the underlying named reference for this unbound term.
Implemented in iceberg::UnboundAggregateImpl< B >, iceberg::UnboundPredicateImpl< B >, iceberg::NamedReference, iceberg::UnboundTransform, and iceberg::UnboundPredicate.
