Method Details

nullable

public boolean nullable()

Returns:

The value of the nullable attribute

fields

public List<Expression> fields()

Specified by:

fields in class Expression.NestedStruct

Returns:

The value of the fields attribute

withNullable

public final ImmutableExpression.NestedStruct 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

withFields

public final ImmutableExpression.NestedStruct withFields(Expression... elements)

Copy the current immutable object with elements that replace the content of fields.

Parameters:

elements - The elements to set

Returns:

A modified copy of this object

withFields

public final ImmutableExpression.NestedStruct withFields(Iterable<? extends Expression> elements)

Copy the current immutable object with elements that replace the content of fields. A shallow reference equality check is used to prevent copying of the same value by returning this.

Parameters:

elements - An iterable of fields elements to set

Returns:

A modified copy or this if not changed

equals

public boolean equals(Object another)

This instance is equal to all instances of NestedStruct 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, fields.

Overrides:

hashCode in class Object

Returns:

hashCode value

toString

public String toString()

Prints the immutable value NestedStruct with attribute values.

Overrides:

toString in class Object

Returns:

A string representation of the value

copyOf

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

Creates an immutable copy of a Expression.NestedStruct 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 NestedStruct instance

builder

public static ImmutableExpression.NestedStruct.Builder builder()

Creates a builder for NestedStruct.

 ImmutableExpression.NestedStruct.builder()
    .nullable(boolean) // optional nullable
    .addFields|addAllFields(io.substrait.expression.Expression) // fields elements
    .build();
 

Returns:

A new NestedStruct builder
