Method Details

parameters

public Type.Struct parameters()

Specified by:

parameters in class Expression.Lambda

Returns:

The value of the parameters attribute

body

public Expression body()

Specified by:

body in class Expression.Lambda

Returns:

The value of the body attribute

withParameters

public final ImmutableExpression.Lambda withParameters(Type.Struct value)

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

Parameters:

value - A new value for parameters

Returns:

A modified copy or the this object

withBody

public final ImmutableExpression.Lambda withBody(Expression value)

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

Parameters:

value - A new value for body

Returns:

A modified copy or the this object

equals

public boolean equals(Object another)

This instance is equal to all instances of Lambda 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: parameters, body.

Overrides:

hashCode in class Object

Returns:

hashCode value

toString

public String toString()

Prints the immutable value Lambda with attribute values.

Overrides:

toString in class Object

Returns:

A string representation of the value

copyOf

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

Creates an immutable copy of a Expression.Lambda 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 Lambda instance

builder

public static ImmutableExpression.Lambda.Builder builder()

Creates a builder for Lambda.

 ImmutableExpression.Lambda.builder()
    .parameters(io.substrait.type.Type.Struct) // required parameters
    .body(io.substrait.expression.Expression) // required body
    .build();
 

Returns:

A new Lambda builder
