Detailed Description

Base class for bound terms.

Member Function Documentation

Equals()

virtual bool iceberg::BoundTerm::Equals ( const BoundTerm &  other ) const

pure virtual

Returns whether this term is equivalent to another.

Two terms are equivalent if they produce the same values when evaluated.

Parameters

other

Another bound term to compare against

Returns

true if the terms are equivalent, false otherwise

Implemented in iceberg::BoundReference, and iceberg::BoundTransform.

is_unbound()

bool iceberg::BoundTerm::is_unbound ( ) const

inlineoverridevirtual

Returns whether this term is unbound.

Implements iceberg::Term.

MayProduceNull()

virtual bool iceberg::BoundTerm::MayProduceNull ( ) const

pure virtual

Returns whether this term may produce null values.

Implemented in iceberg::BoundReference, and iceberg::BoundTransform.

type()

virtual std::shared_ptr< Type > iceberg::BoundTerm::type ( ) const

pure virtual

Returns the type produced by this term.

Implemented in iceberg::BoundReference, and iceberg::BoundTransform.
