Method Details

nullable

public boolean nullable()

Returns:

The value of the nullable attribute

elementType

public Type elementType()

Specified by:

elementType in class Expression.EmptyListLiteral

Returns:

The value of the elementType attribute

withNullable

public final ImmutableExpression.EmptyListLiteral 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 ImmutableExpression.EmptyListLiteral withElementType(Type 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 EmptyListLiteral 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 EmptyListLiteral with attribute values.

Overrides:

toString in class Object

Returns:

A string representation of the value

copyOf

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

Creates an immutable copy of a Expression.EmptyListLiteral 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 EmptyListLiteral instance

builder

public static ImmutableExpression.EmptyListLiteral.Builder builder()

Creates a builder for EmptyListLiteral.

 ImmutableExpression.EmptyListLiteral.builder()
    .nullable(boolean) // optional nullable
    .elementType(io.substrait.type.Type) // required elementType
    .build();
 

Returns:

A new EmptyListLiteral builder
