    • Method Detail

      • getObject

        public O getObject​(int i)
        Description copied from interface: ObjectTokenSequence
        Gets the value of the specified token as an object.

        This is a reference to the object representing the value. If the object is mutable, changing it modifies the value of the token in the sequence.

        Specified by:
        getObject in interface ObjectTokenSequence<O>
        Parameters:
        i - the position of the token in the sequence
        Returns:
        the value of the token. If the token is null valued, null is returned.

      • getValues

        public void getValues​(int index,
                      O[] values,
                      boolean[] nullFlags,
                      int offset,
                      int length)
        Description copied from interface: ObjectTokenSequence
        Gets the values and null indicators for a range of tokens.

        References to the objects representing the token values are returned. If these objects are mutable, changing any modifies the values of the tokens in the sequence.

        Specified by:
        getValues in interface ObjectTokenSequence<O>
        Parameters:
        index - the starting index of the range
        values - an array into which to place element values
        nullFlags - an array into which to place null indicator values
        offset - the starting offset into the target arrays. That is, elements[offset] and nulls[offset] will get the value and null indicator respectively of the token at position start, and so on.
        length - number of tokens to get

      • setObject

        public void setObject​(int index,
                      O value)
        Sets the token at the specified position to the given object value. If the object is mutable, subsequently modifying it will modify the token in the array.
        Specified by:
        setObject in interface MutableObjectTokenSequence<O>
        Parameters:
        index - the position of the token in the array
        value - the object value to which to set the token. Passing null is equivalent to calling setNull(index).
