    • Method Detail

      • setNull

        public void setNull()
        Description copied from interface: TokenSettable
        Sets the contained value to be null valued.
        Specified by:
        setNull in interface TokenSettable
      • setZero

        public void setZero()
        Description copied from interface: TokenSettable
        Sets the contained value to be zero valued.
        Specified by:
        setZero in interface TokenSettable
      • set

        public void set​(boolean value)
        Description copied from interface: BooleanSettable
        Sets the container to the given boolean value.
        Specified by:
        set in interface BooleanSettable
        Parameters:
        value - boolean value to which to set the container
      • set

        public void set​(TokenValued value)
        Description copied from interface: TokenSettable
        Sets the contained value to the given token value. The given value must have a type compatible with this object.
        Specified by:
        set in interface TokenSettable
        Parameters:
        value - the value to which to set the container
      • isZero

        public final boolean isZero()
        Description copied from interface: ScalarValued
        Indicates whether the value is the zero value for the type. Zero values are not stored in sparse representation formats.
        Specified by:
        isZero in interface ScalarValued
        Returns:
        true if the value is the zero value, false otherwise.
      • asBoolean

        public final boolean asBoolean()
        Description copied from interface: BooleanValued
        Gets the contained boolean value.
        Specified by:
        asBoolean in interface BooleanValued
        Returns:
        the contained value as a boolean. If null valued, as indicated by TokenValued.isNull(), false is returned.
      • isNull

        public final boolean isNull()
        Description copied from interface: TokenValued
        Indicates whether the token is null valued. Tokens support null values analogous to SQL. Before accessing the value of the container, it is usually best to ensure it is not null valued using this method.
        Specified by:
        isNull in interface TokenValued
        Returns:
        true if the token is null valued, false otherwise
