Method Detail

getReducer

public BinaryOperator<T> getReducer()

Specified by:

getReducer in interface ArrayReducerOperator<T>

Returns:

The value of the reducer attribute

getArrayExpression

public Expression getArrayExpression()

Specified by:

getArrayExpression in interface ArrayReducerOperator<T>

Returns:

The value of the arrayExpression attribute

getPlaceholderValue

@Nullable
public @Nullable Object getPlaceholderValue()

Specified by:

getPlaceholderValue in interface ArrayReducerOperator<T>

Returns:

The value of the placeholderValue attribute

withReducer

public final ImmutableArrayReducerOperator<T> withReducer(BinaryOperator<T> value)

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

Parameters:

value - A new value for reducer

Returns:

A modified copy of the this object

withArrayExpression

public final ImmutableArrayReducerOperator<T> withArrayExpression(Expression value)

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

Parameters:

value - A new value for arrayExpression

Returns:

A modified copy of the this object

withPlaceholderValue

public final ImmutableArrayReducerOperator<T> withPlaceholderValue(@Nullable
                                                                   @Nullable Object value)

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

Parameters:

value - A new value for placeholderValue (can be null)

Returns:

A modified copy of the this object

equals

public boolean equals(@Nullable
                      Object another)

This instance is equal to all instances of ImmutableArrayReducerOperator 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: reducer, arrayExpression, placeholderValue.

Overrides:

hashCode in class Object

Returns:

hashCode value

toString

public String toString()

Prints the immutable value ArrayReducerOperator with attribute values.

Overrides:

toString in class Object

Returns:

A string representation of the value

of

public static <T> ImmutableArrayReducerOperator<T> of(BinaryOperator<T> reducer,
                                                      Expression arrayExpression)

Construct a new immutable ArrayReducerOperator instance.

Type Parameters:

T - generic parameter T

Parameters:

reducer - The value for the reducer attribute

arrayExpression - The value for the arrayExpression attribute

Returns:

An immutable ArrayReducerOperator instance

copyOf

public static <T> ImmutableArrayReducerOperator<T> copyOf(ArrayReducerOperator<T> instance)

Creates an immutable copy of a ArrayReducerOperator value. Uses accessors to get values to initialize the new immutable instance. If an instance is already immutable, it is returned as is.

Type Parameters:

T - generic parameter T

Parameters:

instance - The instance to copy

Returns:

A copied immutable ArrayReducerOperator instance

builder

public static <T> ImmutableArrayReducerOperator.Builder<T> builder()

Creates a builder for ImmutableArrayReducerOperator.

 ImmutableArrayReducerOperator.<T>builder()
    .reducer(function.BinaryOperator<T>) // required reducer
    .arrayExpression(io.dialob.program.model.Expression) // required arrayExpression
    .placeholderValue(Object | null) // nullable placeholderValue
    .build();
 

Type Parameters:

T - generic parameter T

Returns:

A new ImmutableArrayReducerOperator builder
