Package io.substrait.function

Class ImmutableTypeExpression.Struct.Builder

java.lang.Object

io.substrait.function.ImmutableTypeExpression.Struct.Builder

Enclosing class:

ImmutableTypeExpression.Struct

public static final class ImmutableTypeExpression.Struct.Builder
extends Object

Builds instances of type Struct. Initialize attributes and then invoke the build() method to create an immutable instance.

Builder is not thread-safe and generally should not be stored in a field or collection, but instead used immediately to create instances.

final ImmutableTypeExpression.Struct.Builder	addFields(TypeExpression element)	Adds one element to fields list.
final ImmutableTypeExpression.Struct.Builder	addFields(TypeExpression... elements)	Adds elements to fields list.
ImmutableTypeExpression.Struct	build()	Builds a new Struct.
final ImmutableTypeExpression.Struct.Builder	fields(Iterable<? extends TypeExpression> elements)	Sets or replaces all elements for fields list.
final ImmutableTypeExpression.Struct.Builder	from(NullableType instance)	Fill a builder with attribute values from the provided io.substrait.function.NullableType instance.
final ImmutableTypeExpression.Struct.Builder	from(TypeExpression.Struct instance)	Fill a builder with attribute values from the provided io.substrait.function.TypeExpression.Struct instance.
final ImmutableTypeExpression.Struct.Builder	nullable(boolean nullable)	Initializes the value for the nullable attribute.
