Class AbstractBoolean2ObjectFunction<V>

  • All Implemented Interfaces:
    Boolean2ObjectFunction<V>, Function<Boolean,​V>, Serializable, Function<Boolean,​V>

    public abstract class AbstractBoolean2ObjectFunction<V>
    extends Object
    implements Boolean2ObjectFunction<V>, Serializable
    An abstract class providing basic methods for functions implementing a type-specific interface.

    This class handles directly a default return value (including methods to access it). Instances of classes inheriting from this class have just to return defRetValue to denote lack of a key in type-specific methods. The value is serialized.

    Implementing subclasses have just to provide type-specific get(), type-specific containsKey(), and size() methods.

        public V defaultReturnValue()
        Description copied from interface: Boolean2ObjectFunction
        Gets the default return value.

        This default implementation just return the default null value of the type (null for objects, 0 for scalars, false for Booleans).

        Specified by:
        defaultReturnValue in interface Boolean2ObjectFunction<V>
        Returns:
        the current default return value.
