Class 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

      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

      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
