Method Details

getType

public Type getType()

Returns:

The value of the type attribute

input

public Rel input()

Specified by:

input in class Expression.ScalarSubquery

Returns:

The value of the input attribute

withType

public final ImmutableExpression.ScalarSubquery 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

withInput

public final ImmutableExpression.ScalarSubquery withInput(Rel value)

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

Parameters:

value - A new value for input

Returns:

A modified copy or the this object

equals

public boolean equals(Object another)

This instance is equal to all instances of ScalarSubquery 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, input.

Overrides:

hashCode in class Object

Returns:

hashCode value

toString

public String toString()

Prints the immutable value ScalarSubquery with attribute values.

Overrides:

toString in class Object

Returns:

A string representation of the value

copyOf

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

Creates an immutable copy of a Expression.ScalarSubquery 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 ScalarSubquery instance

builder

public static ImmutableExpression.ScalarSubquery.Builder builder()

Creates a builder for ScalarSubquery.

 ImmutableExpression.ScalarSubquery.builder()
    .type(io.substrait.type.Type) // required type
    .input(io.substrait.relation.Rel) // required input
    .build();
 

Returns:

A new ScalarSubquery builder
