Class AbstractBoolean2ShortFunction

  • All Implemented Interfaces:
    Boolean2ShortFunction, Function<java.lang.Boolean,​java.lang.Short>, java.io.Serializable, java.util.function.Function<java.lang.Boolean,​java.lang.Short>

    public abstract class AbstractBoolean2ShortFunction
    extends java.lang.Object
    implements Boolean2ShortFunction, 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 void defaultReturnValue​(short rv)
        Description copied from interface: Boolean2ShortFunction
        Sets the default return value (optional operation). This value must be returned by type-specific versions of get(), put() and remove() to denote that the map does not contain the specified key. It must be 0/false/null by default.
        Specified by:
        defaultReturnValue in interface Boolean2ShortFunction
        Parameters:
        rv - the new default return value.

        public short defaultReturnValue()
        Description copied from interface: Boolean2ShortFunction
        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 Boolean2ShortFunction
        Returns:
        the current default return value.
