Class ImmutableVariableReference<T>

  • All Implemented Interfaces:
    VariableReference<T>, Expression, Serializable
    @ParametersAreNonnullByDefault
@Generated("org.immutables.processor.ProxyProcessor")
@Immutable
@CheckReturnValue
public final class ImmutableVariableReference<T>
extends Object
implements VariableReference<T>
    Immutable implementation of VariableReference.

    Use the builder to create immutable instances: ImmutableVariableReference.builder(). Use the static factory method to create immutable instances: ImmutableVariableReference.of().

    • Method Detail

      • withValueType

        public final ImmutableVariableReference<T> withValueType​(ValueType 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 of the this object

      • withItemId

        public final ImmutableVariableReference<T> withItemId​(ItemId value)
        Copy the current immutable object by setting a value for the itemId attribute. A shallow reference equality check is used to prevent copying of the same value by returning this.
        Parameters:
        value - A new value for itemId
        Returns:
        A modified copy of the this object

      • equals

        public boolean equals​(@Nullable
                      Object another)
        This instance is equal to all instances of ImmutableVariableReference 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: valueType, itemId.
        Overrides:
        hashCode in class Object
        Returns:
        hashCode value

      • toString

        public String toString()
        Prints the immutable value VariableReference with attribute values.
        Overrides:
        toString in class Object
        Returns:
        A string representation of the value

      • of

        public static <T> ImmutableVariableReference<T> of​(ItemId itemId,
                                                   ValueType valueType)
        Construct a new immutable VariableReference instance.
        Type Parameters:
        T - generic parameter T
        Parameters:
        itemId - The value for the itemId attribute
        valueType - The value for the valueType attribute
        Returns:
        An immutable VariableReference instance

      • copyOf

        public static <T> ImmutableVariableReference<T> copyOf​(VariableReference<T> instance)
        Creates an immutable copy of a VariableReference 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 VariableReference instance

      • builder

        public static <T> ImmutableVariableReference.Builder<T> builder()
        Creates a builder for ImmutableVariableReference. 
         ImmutableVariableReference.&lt;T&gt;builder()
    .valueType(io.dialob.rule.parser.api.ValueType) // required valueType
    .itemId(io.dialob.executor.model.ItemId) // required itemId
    .build();
        Type Parameters:
        T - generic parameter T
        Returns:
        A new ImmutableVariableReference builder
