Detailed Description

template<typename B>
class iceberg::UnboundAggregateImpl< B >

Template for unbound aggregates that carry a term and operation.

Member Function Documentation

Bind()

template<typename B >

Result< std::shared_ptr< Expression > > iceberg::UnboundAggregateImpl< B >::Bind ( const Schema &  schema, bool  case_sensitive  ) const

overridevirtual

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

Implements iceberg::Unbound< Expression >.

reference()

template<typename B >

std::shared_ptr< NamedReference > iceberg::UnboundAggregateImpl< B >::reference ( )

inlineoverridevirtual
