Abstract Value Members

  1. abstract def column: Int

    The index of the character relative to the beginning of the line, as a 16 bit java character.

    The index of the character relative to the beginning of the line, as a 16 bit java character. (0 based)

  2. abstract def consume(n: Int): Unit

    Consume n code points.

  3. abstract def consume(): Unit

    Consume and advance to the next code point.

  4. abstract def countSpaces(offset: Int = 0, max: Int = MAX_VALUE): Int
  5. abstract def countWhiteSpaces(offset: Int = 0): Int

    Count the number of whiteSpaces from the specified offset

  6. abstract def createMark(): Mark

    Create a mark in the Input so you can reset the input to it later

  7. abstract def current: Int

    The current code point character in the input (or LexerInput#Eof if the EoF was reached).

  8. abstract def line: Int

    The current Line number (0 based).

  9. abstract def lookAhead(i: Int): Int

    Return the character i characters ahead of the current position, (or LexerInput#Eof if the EoF was reached).

  10. abstract def nonEof: Boolean

    We're not at the Eof

  11. abstract def offset: Int

    The absolute offset (0..n) of the current character.

  12. abstract def position: Position

    the triple (line, column, offset)

  13. abstract def reset(mark: Mark): Unit

    Reset the input to the specified offset

  14. abstract def subSequence(start: Int, end: Int): CharSequence

    Return the sub-sequence of characters between the specified positions
