Class ImmutableRoot.Builder

java.lang.Object
io.substrait.plan.ImmutableRoot.Builder
Enclosing class:
ImmutableRoot
public static final class ImmutableRoot.Builder extends Object
Builds instances of type ImmutableRoot. 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.
