Method Details

type

public Type type()

Specified by:

type in class Expression.NullLiteral

Returns:

The value of the type attribute

withType

public final ImmutableExpression.NullLiteral withType(Type value)

Copy the current immutable object by setting a value for the type attribute. A shallow reference equality check is used to prevent copying of the same value by returning this.

Parameters:

value - A new value for type

Returns:

A modified copy or the this object

equals

public boolean equals(Object another)

This instance is equal to all instances of NullLiteral 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: type.

Overrides:

hashCode in class Object

Returns:

hashCode value

toString

public String toString()

Prints the immutable value NullLiteral with attribute values.

Overrides:

toString in class Object

Returns:

A string representation of the value

copyOf

public static ImmutableExpression.NullLiteral copyOf(Expression.NullLiteral instance)

Creates an immutable copy of a Expression.NullLiteral 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 NullLiteral instance

builder

public static ImmutableExpression.NullLiteral.Builder builder()

Creates a builder for NullLiteral.

 ImmutableExpression.NullLiteral.builder()
    .type(io.substrait.type.Type) // required type
    .build();
 

Returns:

A new NullLiteral builder
