Class ImmutableConstant<T>

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

    • Method Detail

      • getValue

        public T getValue()
        Specified by:
        getValue in interface Constant<T>
        Returns:
        The value of the value attribute

      • withValue

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

      • withValueType

        public final ImmutableConstant<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

      • equals

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

      • toString

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

      • copyOf

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

      • builder

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