Package io.substrait.relation

Class ImmutableExpand.ConsistentField

java.lang.Object
io.substrait.relation.Expand.ConsistentField
io.substrait.relation.ImmutableExpand.ConsistentField
All Implemented Interfaces:
Expand.ExpandField
Enclosing class:
ImmutableExpand
public static final class ImmutableExpand.ConsistentField extends Expand.ConsistentField
Immutable implementation of Expand.ConsistentField.

Use the builder to create immutable instances: ImmutableExpand.ConsistentField.builder().

  • Method Details

    • getExpression

      public Expression getExpression()
      Returns the expression that defines the field value.
      Specified by:
      getExpression in class Expand.ConsistentField
      Returns:
      the defining expression

    • withExpression

      public final ImmutableExpand.ConsistentField withExpression(Expression value)
      Copy the current immutable object by setting a value for the expression attribute. A shallow reference equality check is used to prevent copying of the same value by returning this.
      Parameters:
      value - A new value for expression
      Returns:
      A modified copy or the this object

    • equals

      public boolean equals(Object another)
      This instance is equal to all instances of ConsistentField that have equal attribute values.
      Overrides:
      equals in class Object
      Returns:
      true if this is equal to another instance

    • hashCode

      public int hashCode()
      Computes a hash code from attributes: expression.
      Overrides:
      hashCode in class Object
      Returns:
      hashCode value

    • toString

      public String toString()
      Prints the immutable value ConsistentField with attribute values.
      Overrides:
      toString in class Object
      Returns:
      A string representation of the value

    • copyOf

      public static ImmutableExpand.ConsistentField copyOf(Expand.ConsistentField instance)
      Creates an immutable copy of a Expand.ConsistentField value. Uses accessors to get values to initialize the new immutable instance. If an instance is already immutable, it is returned as is.
      Parameters:
      instance - The instance to copy
      Returns:
      A copied immutable ConsistentField instance

    • builder

      public static ImmutableExpand.ConsistentField.Builder builder()
      Creates a builder for ConsistentField. 
       ImmutableExpand.ConsistentField.builder()
    .expression(io.substrait.expression.Expression) // required expression
    .build();
      Returns:
      A new ConsistentField builder
