Class ImmutableTypeExpression.ListType

java.lang.Object
io.substrait.function.TypeExpression.BaseTypeExpression
io.substrait.function.TypeExpression.ListType
io.substrait.function.ImmutableTypeExpression.ListType
All Implemented Interfaces:
NullableType, TypeExpression
Enclosing class:
ImmutableTypeExpression
public static final class ImmutableTypeExpression.ListType extends TypeExpression.ListType
Immutable implementation of TypeExpression.ListType.

Use the builder to create immutable instances: ImmutableTypeExpression.ListType.builder().

  • Method Details

    • nullable

      public boolean nullable()
      Returns:
      The value of the nullable attribute

    • elementType

      public TypeExpression elementType()
      Specified by:
      elementType in class TypeExpression.ListType
      Returns:
      The value of the elementType attribute

    • withNullable

      public final ImmutableTypeExpression.ListType withNullable(boolean value)
      Copy the current immutable object by setting a value for the nullable attribute. A value equality check is used to prevent copying of the same value by returning this.
      Parameters:
      value - A new value for nullable
      Returns:
      A modified copy or the this object

    • withElementType

      public final ImmutableTypeExpression.ListType withElementType(TypeExpression value)
      Copy the current immutable object by setting a value for the elementType attribute. A shallow reference equality check is used to prevent copying of the same value by returning this.
      Parameters:
      value - A new value for elementType
      Returns:
      A modified copy or the this object

    • equals

      public boolean equals(Object another)
      This instance is equal to all instances of ListType 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: nullable, elementType.
      Overrides:
      hashCode in class Object
      Returns:
      hashCode value

    • toString

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

    • copyOf

      public static ImmutableTypeExpression.ListType copyOf(TypeExpression.ListType instance)
      Creates an immutable copy of a TypeExpression.ListType 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 ListType instance

    • builder

      public static ImmutableTypeExpression.ListType.Builder builder()
      Creates a builder for ListType. 
       ImmutableTypeExpression.ListType.builder()
    .nullable(boolean) // required nullable
    .elementType(io.substrait.function.TypeExpression) // required elementType
    .build();
      Returns:
      A new ListType builder
