Class AbstractBoolean2BooleanFunction

  • All Implemented Interfaces:
    Boolean2BooleanFunction, Function<java.lang.Boolean,​java.lang.Boolean>, java.io.Serializable, java.util.function.Function<java.lang.Boolean,​java.lang.Boolean>

    public abstract class AbstractBoolean2BooleanFunction
    extends java.lang.Object
    implements Boolean2BooleanFunction, java.io.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 boolean defaultReturnValue()
        Description copied from interface: Boolean2BooleanFunction
        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 Boolean2BooleanFunction
        Returns:
        the current default return value.
