Method Details

nullable

public boolean nullable()

Returns:

The value of the nullable attribute

keyType

public Type keyType()

Specified by:

keyType in class Expression.EmptyMapLiteral

Returns:

The value of the keyType attribute

valueType

public Type valueType()

Specified by:

valueType in class Expression.EmptyMapLiteral

Returns:

The value of the valueType attribute

withNullable

public final ImmutableExpression.EmptyMapLiteral 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

withKeyType

public final ImmutableExpression.EmptyMapLiteral withKeyType(Type value)

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

Parameters:

value - A new value for keyType

Returns:

A modified copy or the this object

withValueType

public final ImmutableExpression.EmptyMapLiteral withValueType(Type value)

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

Parameters:

value - A new value for valueType

Returns:

A modified copy or the this object

equals

public boolean equals(Object another)

This instance is equal to all instances of EmptyMapLiteral 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, keyType, valueType.

Overrides:

hashCode in class Object

Returns:

hashCode value

toString

public String toString()

Prints the immutable value EmptyMapLiteral with attribute values.

Overrides:

toString in class Object

Returns:

A string representation of the value

copyOf

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

Creates an immutable copy of a Expression.EmptyMapLiteral 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 EmptyMapLiteral instance

builder

public static ImmutableExpression.EmptyMapLiteral.Builder builder()

Creates a builder for EmptyMapLiteral.

 ImmutableExpression.EmptyMapLiteral.builder()
    .nullable(boolean) // optional nullable
    .keyType(io.substrait.type.Type) // required keyType
    .valueType(io.substrait.type.Type) // required valueType
    .build();
 

Returns:

A new EmptyMapLiteral builder
