Detailed Description

Bound predicates contain bound terms and can be evaluated.

Member Function Documentation

◆ Evaluate()

Result< Literal > iceberg::BoundPredicate::Evaluate ( const StructLike & data ) const

overridevirtual

Evaluate this expression against a row-based data.

Implements iceberg::Bound.

◆ is_bound_predicate()

bool iceberg::BoundPredicate::is_bound_predicate ( ) const

inlineoverridevirtual

Reimplemented from iceberg::Expression.

◆ kind()

virtual Kind iceberg::BoundPredicate::kind ( ) const

pure virtual

Returns the kind of this bound predicate.

Implemented in iceberg::BoundUnaryPredicate, iceberg::BoundLiteralPredicate, and iceberg::BoundSetPredicate.

◆ reference()

std::shared_ptr< BoundReference > iceberg::BoundPredicate::reference ( )

inlineoverridevirtual

Returns the underlying bound reference for this term.

Implements iceberg::Bound.

◆ Test()

virtual Result< bool > iceberg::BoundPredicate::Test ( const Literal & value ) const

pure virtual

Test a value against this predicate.

Parameters

value The literal value to test

Returns: true if the predicate passes, false otherwise

Implemented in iceberg::BoundUnaryPredicate, iceberg::BoundLiteralPredicate, and iceberg::BoundSetPredicate.
