Class ImmutableType.VarChar

java.lang.Object
io.substrait.type.Type.VarChar
io.substrait.type.ImmutableType.VarChar
All Implemented Interfaces:
FunctionArg, NullableType, ParameterizedType, TypeExpression, Type
Enclosing class:
ImmutableType
public static final class ImmutableType.VarChar extends Type.VarChar
Immutable implementation of Type.VarChar.

Use the builder to create immutable instances: ImmutableType.VarChar.builder().

  • Method Details

    • nullable

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

    • length

      public int length()
      Specified by:
      length in class Type.VarChar
      Returns:
      The value of the length attribute

    • withNullable

      public final ImmutableType.VarChar 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

    • withLength

      public final ImmutableType.VarChar withLength(int value)
      Copy the current immutable object by setting a value for the length attribute. A value equality check is used to prevent copying of the same value by returning this.
      Parameters:
      value - A new value for length
      Returns:
      A modified copy or the this object

    • equals

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

    • toString

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

    • copyOf

      public static ImmutableType.VarChar copyOf(Type.VarChar instance)
      Creates an immutable copy of a Type.VarChar 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 VarChar instance

    • builder

      public static ImmutableType.VarChar.Builder builder()
      Creates a builder for VarChar. 
       ImmutableType.VarChar.builder()
    .nullable(boolean) // required nullable
    .length(int) // required length
    .build();
      Returns:
      A new VarChar builder
