java.lang.Object
io.substrait.expression.ImmutableExpression.Lambda.Builder
Enclosing class:
ImmutableExpression.Lambda
public static final class ImmutableExpression.Lambda.Builder extends Object
Builds instances of type Lambda. 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.
