Member Function Documentation

◆ Bind()

Result< std::shared_ptr< BoundTransform > > iceberg::UnboundTransform::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< B >.

◆ kind()

Kind iceberg::UnboundTransform::kind ( ) const

inlineoverridevirtual

Returns the kind of this term.

Implements iceberg::Term.

◆ Make()

Result< std::unique_ptr< UnboundTransform > > iceberg::UnboundTransform::Make	(	std::shared_ptr< NamedReference >	ref,
		std::shared_ptr< Transform >	transform
	)

static

Parameters

ref	The term to apply the transformation to
transform	The transformation function to apply

◆ reference()

std::shared_ptr< NamedReference > iceberg::UnboundTransform::reference ( )

inlineoverridevirtual

Implements iceberg::Unbound< B >.

◆ ToString()

std::string iceberg::UnboundTransform::ToString ( ) const

overridevirtual

Get a user-readable string representation.
