  • Method Details

    • setNull

      void setNull(int index)
      Sets the token at the specified position to be null valued.
      Parameters:
      index - the position of the token in the array

    • setNull

      void setNull(int start, int length)
      Sets the tokens in the specified subsequence to be null valued.
      Parameters:
      start - the starting index of the subsequence in the array
      length - the length of the subsequence

    • setZero

      void setZero(int index)
      Sets the token at the specified position to be zero valued.
      Parameters:
      index - the position of the token in the array

    • setZero

      void setZero(int start, int length)
      Sets the tokens in the specified subsequence to be zero valued.
      Parameters:
      start - the starting index of the subsequence in the array
      length - the length of the subsequence

    • setValue

      void setValue(int index, TokenValued value)
      Sets the token at the specified position to the given value.
      Parameters:
      index - the position of the token in the array
      value - the value to which to set the token. This value must be of an appropriate type for the array.

    • fillValue

      void fillValue(int start, int length, TokenValued value)
      Sets the tokens in the specified subsequence to the given value.
      Parameters:
      start - the starting index of the subsequence in the array
      length - the length of the subsequence
      value - the value to which to set the tokens. This value must be of an appropriate type for the array

    • setValues

      void setValues(int start, TokenSequence values, int offset, int length)
      Sets the tokens in the specified subsequence of the array to the corresponding values from a subsequence of the given source sequence.
      Parameters:
      start - the starting index of the subsequence in the array
      values - the source sequence. This sequence must be of an appropriate type for the array.
      offset - the starting index in the source sequence. Corresponding values will be taken relative to this position. That is, the value of the token at position offset in values will be assigned to the token at position start, and so on.
      length - the number of tokens to copy

    • appendZero

      void appendZero()
      Appends a zero value to this sequence.

    • appendZero

      void appendZero(int count)
      Appends the specified number of zero values to this sequence.
      Parameters:
      count - the number of zero values to append

    • appendNull

      void appendNull()
      Appends a null value to this sequence.

    • appendNull

      void appendNull(int count)
      Appends the specified number of null values to this sequence.
      Parameters:
      count - the number of null values to append

    • reset

      void reset()
      Removes all elements from the sequence.

    • getTokenSetter

      TokenSettable getTokenSetter(int index)
      Returns a mutator for the given index.
      Parameters:
      index - the position
      Returns:
      a mutator for the given index.
